Allergic Rhinitis: Symptoms, Causes & Treatment

Allergic rhinitis is inflammation of the lining of the nose caused by the immune system overreacting to harmless substances such as dust or pollen. It is one of the most common conditions in Egypt, and although for most people it is not a dangerous illness, it wears a person down: broken sleep, bouts of sneezing, a nose that never quite clears, and trouble concentrating at work or at school.

This article explains what allergic rhinitis is, what causes it, the symptoms it produces, the complications it can lead to when it is left uncontrolled, and how it is assessed and managed by the ear, nose, and throat (ENT) team at Town Hospital in New Cairo. One point is worth making from the start: allergic rhinitis is controlled rather than cured. The underlying tendency stays with you, but with good control you can go for long stretches with few symptoms, or none at all.

What Is Allergic Rhinitis?

Allergic rhinitis is a common condition that develops when the immune system overreacts to everyday substances in the environment known as allergens, or triggers. These substances are not harmful in themselves, but in someone with an allergy the body treats them as a threat and releases chemicals such as histamine. It is these chemicals that produce the troublesome symptoms in the nose and airway.

Symptoms of Allergic Rhinitis

The symptoms of allergic rhinitis commonly include:

Repeated, disruptive sneezing, often in bouts
A blocked, congested nose
A runny nose, usually with thin, clear discharge
Itching in the nose and eyes
Watery, red, irritated eyes
Itching and irritation in the throat
Cough
Changes in the sound of the voice
Tiredness and a run-down feeling
Itching or redness of the skin

If these symptoms are persistent or keep coming back, it is important to be seen by a doctor for a proper assessment and an accurate diagnosis. The doctor may recommend allergy testing to confirm whether a specific allergy is present and to guide the treatment that suits your case.

Complications of Allergic Rhinitis

Allergic rhinitis, whether seasonal or year-round, is for most people a nuisance rather than a danger. In some cases, however, it can lead to more serious health problems, particularly when it is left uncontrolled for long periods. Possible complications include:

Chronic sinusitis: ongoing congestion and swelling of the nasal lining, together with the disturbed airflow that goes with it, trap secretions in the paranasal sinuses and interfere with their drainage, which can lead to long-standing sinus inflammation with facial pain and a feeling of pressure and congestion.
Asthma: in some people allergic rhinitis occurs alongside asthma, or is linked with a greater risk of asthma attacks.
Bronchitis: allergy may raise the risk of bronchitis, in which the airways in the chest become inflamed and irritated.
Disturbed sleep: constant congestion and irritation affect the quality of sleep and can lead to problems such as snoring and broken or lost sleep.
Effects on the middle ear: allergic rhinitis can affect the pressure and ventilation of the middle ear, leaving the ear feeling blocked.
Effects on the skin: some people develop itching or a rash as part of the allergic reaction.
Effects on mood and daily functioning: in some people, persistent symptoms and disturbed sleep go hand in hand with low mood and anxiety.

Anyone with severe or long-standing symptoms should be assessed by a doctor rather than trying to manage the problem alone. Management is decided after examination, and it usually combines reducing exposure to the trigger, keeping the home environment clean, and any medication the doctor chooses from the classes described later on this page. The aim is to keep the condition controlled and to prevent the complications described above.

Medications for Allergic Rhinitis: What Each Class Does and What It Does Not Do

No single medication suits every patient. Choosing the drug class, deciding the order in which classes are used, and judging how well the patient responds are all medical decisions. They rest on an examination of the nose, on how severe the symptoms are and how long they persist, on the patient's age and general health, and on any other medications being taken. Many mild, intermittent cases improve with reduced exposure to the allergen (the substance that triggers the allergy) and with simple measures, while moderate or persistent symptoms need medical evaluation. What follows is general educational information about the recognized drug classes and the limits of each. It describes classes only, with no brand names and no doses. It is not a plan for self-treatment, and it is not an order of use to be followed without a doctor.

Intranasal Corticosteroid Sprays

The most effective class: These are considered the single most effective drug class in moderate to severe or persistent allergic rhinitis, because they treat the inflammation in the lining of the nose itself, easing congestion, sneezing, runny nose, and itching together.
They are not oral cortisone, and they are not cortisone injections: They act locally on the lining of the nose in small amounts, and little of the drug is absorbed into the body as a whole, so they are not the same thing as cortisone tablets or injections. Confusing the two is a common reason a patient refuses the spray they were prescribed and turns to decongestant sprays instead, which is the more dangerous choice, as explained below.
The effect is gradual, not immediate: The full effect does not appear with the first use. It builds over days, and it may take around two weeks to reach the best response. Deciding that the spray "did not work" after a day or two is judging too soon.
Why the doctor insists on regular use: The benefit comes from using the spray regularly throughout the period of exposure to the allergen, not only when symptoms flare. Using it on and off is one of the most common reasons these sprays appear to fail. How long to use them, and when, is set by the doctor for each case.
What they do not do: They do not open a blocked nose within minutes. They are not an instant reliever for severe congestion.
Cautions: They may cause dryness or irritation inside the nose, or a minor nosebleed. Correct technique, which means aiming the spray away from the nasal septum, reduces this, and a doctor or pharmacist will explain it. Nosebleeds that keep coming back or do not settle are a reason to stop the spray and see the doctor, not to carry on.
Conditions to tell the doctor about before use: Narrow-angle glaucoma or cataracts, recent nasal surgery or injury, or an ulcer of the nasal septum. Long-term use in children requires supervision and follow-up that includes monitoring growth and height.
Check which type of spray is in your hand: Packages look alike on pharmacy shelves, and a corticosteroid spray is not a decongestant spray and not a saline spray. Read the class written on the package, and ask the pharmacist if you have any doubt at all, because many cases of dependence on a decongestant spray began with two packages being mixed up. It is also never appropriate to use a spray that was prescribed for someone else.

Oral Antihistamines

What they do: They ease sneezing, runny nose, and itching of the nose and eyes, and they begin to work fairly quickly.
What they do not do: Their effect on nasal congestion is limited compared with corticosteroid sprays, so they may not be enough on their own for someone whose main complaint is a blocked nose.
The older, sedating generation: Many of its forms are sold without a prescription, and being easy to obtain is not evidence that it is the most suitable choice. It crosses the blood-brain barrier, so it causes drowsiness, slowed reactions, and poor concentration. That is a real danger for drivers and machine operators, and a known cause of reduced attention and poorer schoolwork in students. Its sedating effect may also carry over into the following morning, even without any clear feeling of sleepiness.
The older generation, further cautions: It has anticholinergic effects, among them dry mouth, difficulty passing urine or urinary retention, and worsening of narrow-angle glaucoma. Older people are affected more strongly, and may experience dizziness, mental confusion, or falls. It must never be given to a child in order to make the child sleep or to keep the child calm. For these reasons, current treatment guidelines no longer place this generation first in line.
The newer generation (non-sedating or less sedating): It is less likely to cause drowsiness and lasts longer, and it is what treatment guidelines generally prefer when this class is needed, with the choice still resting with the doctor. Even so, some people feel a degree of sluggishness with it, so it is wise to watch for that in the first days before driving or operating machinery.
A practical warning: Many combination products marketed for the common cold already contain an older-generation antihistamine or a decongestant, so a patient can end up taking two products carrying the same ingredient without realizing it.

Intranasal Antihistamines (Spray)

What they do: They are given locally inside the nose, they work faster than tablets taken by mouth, and they help nasal symptoms in particular, such as sneezing, runny nose, and itching.
Where they fit: They are used on their own in some cases, and combined with a corticosteroid spray in other moderate or severe persistent cases. That combination is a medical decision, not a personal judgment call.
Cautions: They may leave a bitter taste in some patients, which is one of the most common reasons people stop them. More importantly, they may cause drowsiness in some patients even though they act locally, so it is a mistake to assume that a spray cannot sedate, and the same caution about driving and operating machinery applies to them.

Decongestants: The Most Important Warning on This Page

Two different categories, not one: A topical spray applied into the nose, and tablets or syrup taken by mouth. Each has its own problem, and the warning below about rebound applies specifically to the topical spray.
What they do: They narrow the blood vessels in the lining of the nose, and so they open the airway noticeably quickly.
What they do not do: They do not treat the allergy itself, and they do not ease sneezing, itching, or allergic eye symptoms. All they give is temporary relief of congestion.
Rebound congestion (rhinitis medicamentosa), specific to the topical spray: These sprays are sold without a prescription and are used very widely, and continuous use for as little as a few days is enough to set up a pattern in which the congestion returns worse than before every time the spray wears off. The patient then uses more of it and the condition worsens further, in a vicious cycle that may last for months and make breathing through the nose almost impossible without the spray. This is why the length of time they are used is a medical decision and is not left to the patient's own judgment.
It is not limited to allergy patients: The same cycle takes hold in someone who uses the spray for a passing cold, and that is where the problem starts for many people.
Breaking the cycle: If a patient reaches this point, getting out of it requires medical supervision and an alternative plan. Staying on the spray and waiting for things to settle on their own is not appropriate.
Children: Decongestant sprays are not given to young children except by a medical decision.
Oral decongestants: These carry their own cautions in patients with high blood pressure, heart disease, heart rhythm disorders, an overactive thyroid, narrow-angle glaucoma, and an enlarged prostate or difficulty passing urine, and they may cause insomnia, nervousness, and palpitations. They too are not given to young children except by a medical decision.

Leukotriene Receptor Antagonists

Where they fit: They are a supporting option rather than a first-line treatment for allergic rhinitis, and they are less effective in it than corticosteroid sprays.
When they are considered: They are considered particularly in people who have both allergic rhinitis and asthma, because the two conditions share a common pathway, or in people for whom the other options have not been enough.
An important safety warning: Psychiatric and neurological effects have been seen in some patients, including insomnia, nightmares, anxiety, agitation, and mood swings, and, in rare cases, thoughts of self-harm. Official drug warnings about this have been issued in several countries. For this reason they are dispensed by a medical decision and with follow-up, and the doctor must be told immediately if any change of this kind appears, in an adult or in a child.

Saline Nasal Irrigation: A Supportive Nondrug Measure

What it does: It clears mucus, pollen, and trapped dust from the lining of the nose, eases irritation and congestion, and, used beforehand, may help the nose get more benefit from a medicated spray.
Who it suits: It is among the lowest-risk options and suits many children and pregnant women, but it is best to ask the doctor in special situations and after nasal surgery.
Safety conditions: Use sterile water, or water that has been boiled and then cooled, never tap water straight from the faucet, because tap water may carry organisms that treating it to drinking standard does not remove. Clean and dry the irrigation device after every use, and never share it with another person.
Its limits: It does not replace drug treatment in moderate and severe cases, but it is a useful addition to it.

Allergen Immunotherapy (Desensitization)

What it is: The patient is given gradually increasing amounts of the allergen that testing has confirmed they are sensitive to, either by injection under the skin or as a preparation given under the tongue, until the immune system grows accustomed to it and reacts to it less strongly. It is not like ordinary vaccines, and it has nothing to do with the cortisone injections that some people call "the allergy shot."
What sets it apart: It is the only treatment that changes the course of the allergy itself rather than relieving its symptoms, and its effect may continue for a period after the treatment ends.
It is not a quick fix: It runs for years and calls for patience and for keeping to appointments, and the benefit appears gradually over the course of treatment rather than in its first weeks.
A specialist decision: It begins with identifying the allergen precisely, it is decided on by a specialist physician, and it is given in a facility equipped to treat a severe allergic reaction immediately, not merely to observe the patient afterward. It also cannot be used in some conditions, among them unstable asthma, or alongside certain medications.

What Is Not Used to Treat Allergic Rhinitis

Bronchodilators: They act on the lower airways in asthma and bronchospasm, and they have no role in treating allergic rhinitis, because the problem lies in the lining of the nose and not in the airways of the lungs. If the patient also has asthma, the asthma is treated separately under its own medical plan, and not as a treatment for the nose.
Oral cortisone and long-acting depot injections: Some patients turn to what they call "the allergy shot," which is usually a long-acting steroid that acts on the whole body (a systemic steroid). Steroids of this kind are not a routine treatment for allergic rhinitis, and treatment guidelines advise avoiding depot injections in particular, because their effect spreads through the entire body for weeks and cannot be taken back if a complication appears. Their effects include raised blood sugar, raised blood pressure, thinning of the bones, and joint damage when they are repeated. A steroid that acts on the whole body is used only as an exception, for a short period, by a doctor's decision, and in very limited cases.
Nonsteroidal anti-inflammatory drugs, the anti-inflammatory painkillers: They are not a treatment for allergic rhinitis, and they do not act on the allergic mechanism. Their role goes no further than relieving pain or lowering fever when needed, in conditions such as sinusitis. They carry stomach, kidney, and heart cautions, and, most important of all, patients who have both asthma and nasal polyps (fleshy growths inside the nose) can develop a severe respiratory or nasal attack on taking them. Anyone whose symptoms have flared after a painkiller of this type should tell their doctor and avoid it and drugs like it.
Antibiotics: They do not treat allergy. They are meant for proven bacterial infection, and taking them when they are not needed does harm rather than good.

Who Should Ask a Doctor Before Using Any of These Classes

Children: The suitable classes and formulations differ with age, and not everything sold for adults is suitable for a child, especially decongestants and older-generation antihistamines.
Pregnant and breastfeeding women: Some classes are avoided or restricted during pregnancy and breastfeeding, and the decision is made case by case.
Patients with narrow-angle glaucoma, and those with an enlarged prostate or difficulty passing urine: Some classes may make their symptoms worse, particularly older-generation antihistamines and decongestants.
Patients with high blood pressure, heart disease, heart rhythm disorders, diabetes, or an overactive thyroid: Decongestants call for particular caution in these patients, and steroids that act on the whole body raise blood sugar and blood pressure.
Patients with asthma and nasal polyps, and anyone with a previous reaction to painkillers: These groups have special considerations, as set out above.
Anyone taking other medications regularly: Drug interactions are possible, including with sedatives, some neurological and antidepressant medications, and blood pressure medications, so the full list of medications must be shown to the doctor.
Anyone whose symptoms do not improve despite treatment, or whose complaint is a blocked nose on one side only, repeated nosebleeds, loss of the sense of smell, or persistent facial pain: These are signs that call for medical evaluation, not for increasing doses or switching products on your own.
What calls for urgent evaluation: Swelling or redness around the eye, a change in vision or double vision, or a severe headache accompanied by fever.

A closing note: This information is for general awareness only. Determining the appropriate drug class and the appropriate duration for each patient is a medical decision made after examination. This explanation is not a substitute for consulting a specialist physician, and it must not be relied on for self-treatment or for passing one person's medication on to another.

Managing Allergic Rhinitis When Symptoms Persist or Do Not Respond to Treatment

Most mild or seasonal allergic rhinitis improves with reduced exposure to allergens (the substances that set off the allergy) and with the treatment a physician prescribes, and it does not call for the steps described below. What follows is about the cases in which symptoms carry on, or fail to improve, even though the treatment is being followed correctly.

Medications: What Each Class Does and What It Does Not Do

Antihistamines: these ease sneezing, itching, a runny nose, and itchy eyes by blocking the effect of histamine, but they do little for a blocked nose. Someone whose main complaint is congestion may get little relief from them, and that is a common reason people conclude that "the treatment didn't work." Not all antihistamines are alike. The older ones cross into the brain and cause drowsiness, slowed reactions, and poor concentration — which makes them a poor choice for anyone who drives or operates machinery — and they have anticholinergic effects such as dry mouth, urinary retention (difficulty passing urine), and more confusion in older adults. These older, sedating antihistamines are inexpensive and widely sold in Egypt, which is part of why they are still taken so often, including by drivers, machine operators, and schoolchildren. The newer ones cross into the brain far less and cause less drowsiness while working just as well on allergy symptoms, although some people still feel drowsy on them. Some antihistamines also come as nasal sprays that act on the lining of the nose itself.
Intranasal corticosteroid sprays: these act on the inflammation itself in the lining of the nose. They are the most effective class in persistent allergic rhinitis and the only one with a meaningful effect on congestion. They do not work instantly, however: the effect builds gradually over days and reaches its full strength only with regular use. Judging them a failure after a day or two — or reaching for them only on bad days instead of using them regularly — is the most common reason they appear not to work, and the reason many people give up on them early, assuming they do nothing. The usual side effects are dryness in the nose and slight bleeding, and both are less likely when the spray is aimed away from the nasal septum (the wall between the two nostrils). They are very different from steroid (cortisone) injections: the spray acts on the lining of the nose, and only a small amount is absorbed into the body.
A warning that must not be missed — topical decongestants, the sprays and drops sold as "nose openers": they open the nose within minutes, and that is exactly what makes them dangerous. They are sold over the counter in Egypt and are bought freely, with no advice attached. Using them continuously for more than a few days leads to rebound congestion (rhinitis medicamentosa): the blockage comes back worse than before every time the spray wears off, so the person uses more, and a vicious cycle sets in that can last for months, leaving irritation and swelling of the turbinates (the structures inside the nose that warm, humidify, and regulate the air passing through) that looks like allergy getting worse but is not allergy at all. A great deal of what gets called "allergy that does not respond to treatment" is in fact dependence on these sprays, and breaking out of the cycle needs medical supervision. This warning applies to decongestant sprays and drops alone; intranasal corticosteroid sprays and saline do not cause it, and the caution should not be stretched to cover them.
Oral decongestants: these relieve a blocked nose for a while by narrowing blood vessels. They do not treat the allergy and do not stop symptoms from coming back, and they act on the whole body: raising blood pressure, speeding up the heart rate, causing sleeplessness, and making it harder to pass urine in men with an enlarged prostate. They are not suitable for a number of people, among them anyone with high blood pressure, heart disease, an overactive thyroid, or glaucoma.
Leukotriene receptor antagonists: these do less for allergic rhinitis than intranasal corticosteroid sprays, and they are usually considered when the allergy comes together with asthma. Concerns have been raised about possible psychiatric and neurological effects — mood changes, disturbed sleep, and anxiety among them — which makes this a class where the physician weighs benefit against risk, rather than one that is reached for automatically.
Saline nasal irrigation: this is not a medication, but it is a simple, low-risk measure that washes away mucus and trapped allergens and makes the nose more comfortable. It works as support alongside the rest of the treatment, not as a replacement for it. If it is used, it should be made up with sterile water, or with water that has been boiled and then left to cool; using water straight from the tap carries a rare but serious risk of microorganisms getting through the lining of the nose.
The limits of this information: these classes are described here for information only, and they are not a basis for choosing a medication on your own. Which one is used, in what order, and for how long all depend on the pattern and severity of the symptoms, other illnesses, other medications, pregnancy, and age — a medical decision that is made only after an examination.

When Symptoms Persist Despite Correct Treatment

Specialist assessment for cases that do not respond: managing a difficult case starts with an examination by an ear, nose, and throat specialist, including a review of the medical history and nasal endoscopy (a look inside the nose with a thin scope), to confirm that the symptoms really are due to allergy and to rule out the conditions that resemble it: a deviated nasal septum, enlarged turbinates, chronic sinusitis, nasal polyps (fleshy growths), non-allergic (vasomotor) rhinitis, medication-induced rhinitis — most often rebound congestion from decongestant sprays — or the rhinitis that goes with pregnancy. Going over how faithfully the treatment has been taken, and how the spray is actually being used, is an essential part of this assessment, because what gets blamed on "treatment failure" is very often a mistake in how the treatment was used.
Signs that should not be put down to allergy before an examination: some symptoms call for prompt medical assessment rather than being treated as allergic rhinitis. Among them are congestion that persists in one nostril but not the other, repeated nosebleeds from the same side or blood-stained discharge, a lasting loss of the sense of smell, pain or swelling or numbness in the face, a change in vision or swelling around the eye, and a severe headache with fever. Having one of these signs does not necessarily mean a serious illness, but it does need a medical examination to find the cause.
Identifying allergens with allergy testing: when they are needed, allergy tests — the skin prick test, or a blood test for specific IgE antibodies — help narrow down the substances under suspicion. They show that sensitization to a substance is present; they do not by themselves prove that it is what is causing the symptoms. That is why their results are always read alongside the medical history and never on their own: a positive result that does not match what the patient describes is not enough to establish that substance as the cause, and a negative result does not conclusively rule out allergic rhinitis, since there are forms of it confined to the lining of the nose. Before a skin test, the physician will ask for certain medications to be stopped for a time because they make the result unreliable — and that is done on the physician's instruction, not on the patient's own initiative — and the test is carried out somewhere equipped to handle any reaction. A blood test is used when a skin test is not possible: with widespread eczema, for instance, or medications that cannot be stopped, or a previous severe allergic reaction. The value of these tests is that they guide the plan for cutting down exposure and show who may benefit from immunotherapy.

Immunotherapy and Surgical Options

Immunotherapy where there are indications for it: this is the only available treatment that targets the cause of the allergy itself — the immune system's response to the allergen — instead of only relieving symptoms, and it is reserved for selected cases, once the responsible allergen has been identified and shown to fit the symptoms. It is worth being clear that it is not a quick treatment and is not right for every patient. It is given in gradually increasing doses under medical supervision, somewhere equipped to manage a severe allergic reaction, and the patient stays under observation after each dose. Its effect does not become clear for months, and the full course runs for years, with the treating physician deciding how long it should continue in each individual case; stopping early loses the benefit it was started for. It is given either as injections under the skin of the arm or as preparations placed under the tongue. There are situations in which starting it is not advised, asthma that is not under control among them, which is why it is preceded by a full medical assessment.
Surgery for structural causes only: if the assessment shows a structural obstruction in the nose — persistent enlargement of the inferior turbinates, say, or a deviated nasal septum — surgery may be suggested to correct it, after suitable medical treatment has been given for an adequate period. Turbinate swelling caused by overusing decongestant sprays is an exception: it usually settles once the cause is removed and does not call for surgery. Such surgery improves the airway and eases congestion, but it does not treat the allergy itself; sneezing, itching, and a runny nose still need medical follow-up.

An Important Clarification About "Allergy Injections"

There is no injection into the nose that cures allergic rhinitis on the spot: steroid injections into the nasal turbinates are no longer accepted practice, after documented reports of sudden loss of vision caused by embolism (blockage) of the vessels that supply the retina of the eye. Long-acting cortisone injections into the muscle are likewise not advised, because of their effects on the whole body: raised blood sugar, effects on bone including avascular necrosis (the death of part of the bone from an inadequate blood supply), and suppression of the body's own production of cortisol (its natural steroid hormone). Immunotherapy is a different matter: it is given as injections under the skin of the arm or in forms taken under the tongue, it is not given inside the nose, and its effect is slow and cumulative — measured in months and years, not minutes.
Telling these injections apart from intranasal corticosteroid sprays: all of the above is about injections, and none of it extends to the topical intranasal corticosteroid sprays a physician prescribes as part of a treatment plan. The spray acts on the lining of the nose, only a small amount is absorbed into the body, and it does not carry the risks of injections. Choosing the right treatment is a medical decision made after an examination, and not something to start on your own.

Finding the Best Doctor for Allergic Rhinitis Treatment in Egypt

Allergic rhinitis is one of the most common conditions people live with. Its symptoms may show up as nasal congestion, repeated sneezing, red and itchy eyes, and excessive mucus production.

Town Hospital cares for people living with allergic rhinitis, and the plan the medical team puts together may include:

Pinpointing what triggers your allergy: a clinical examination helps identify the likely triggers behind your nasal allergy, whether that is dust, pollen, pets, or something else.
Allergy medication: the doctor may prescribe medication such as an antihistamine to ease symptoms like sneezing and itching. The older sedating antihistamines and the newer non-sedating ones behave very differently, so choosing between them is a clinical decision; the medications section below explains the difference.
An intranasal corticosteroid spray: used to reduce swelling and congestion inside the nose, when the doctor judges it suitable for your case. Sprays of this kind work gradually, building up over days of regular use rather than acting instantly, so they should not be judged after a day or two.
Treatment for the eyes: if your eyes are affected, the doctor may prescribe a topical eye treatment to relieve itching and redness.
Changes to your surroundings and daily habits: these can include staying away from your triggers as much as you can, keeping the home clean, and cleaning the filter in your air conditioner.
Complementary approaches: some patients feel they benefit from complementary remedies such as herbal preparations, but check with your doctor before using any complementary treatment.

What Is the Difference Between Sinusitis and Allergy?

Sinusitis and allergy are two different conditions that affect the respiratory system, and people often ask how to tell them apart. They differ in their causes, their symptoms, and their treatment. Here are the main differences.

Sinusitis

Causes: sinusitis comes from a bacterial or viral infection affecting the sinuses.
Symptoms: nasal congestion, headache, nasal discharge that may be yellow or green, and pain in the face.
Treatment: when the cause is bacterial, the doctor may prescribe an antibiotic, along with pain relief and a decongestant. Decongestants are a short-term measure only. Decongestant nasal sprays and drops open the nose within minutes, and that is exactly what makes them risky: used for more than a few consecutive days they cause rhinitis medicamentosa, in which the blockage comes back worse every time the spray wears off, driving still more use. They are sold over the counter in Egypt, and the medications section below explains this in full. Severe cases sometimes need surgery.

Allergy

Causes: an allergy is an exaggerated reaction of the immune system to particular substances called allergens, such as dust, pollen, and animal dander.
Symptoms: allergic rhinitis can cause a runny nose, itching in the eyes and nose, repeated sneezing, and nasal congestion, and it can affect both the upper airway and the eyes.
Treatment: treatment depends on the cause and is decided by the doctor after an examination. It may include saline nasal irrigation, and pain relief where that is needed. Antihistamines ease allergy symptoms, but they are not a treatment for sinusitis.

In short, sinusitis is inflammation caused by an infection, while an allergy is driven by an overreaction of the immune system. Seeing a doctor matters here, because the right treatment depends on getting the diagnosis right.

Treating Allergic Rhinitis at Town Hospital

Alongside steering clear of the substances that set off your allergy, Town Hospital offers a range of options for treating allergic rhinitis and easing its symptoms. Those options include the following.

Medication Tailored to the Patient

The medical team at Town Hospital tailors medication to the type and severity of each patient's allergic rhinitis. The doctor decides which kind of medication is appropriate after examining you and assessing how severe your symptoms are and how long they last. The medications section below explains these options in more detail.

Improving Your Surroundings and Daily Habits

Town Hospital also advises on practical changes to your home environment and daily routine that reduce how much you are exposed to your triggers, such as using an air purifier and adjusting the way you clean.

Ways to Prevent Allergic Rhinitis Symptoms

Stay away from the substances that set off your allergy, such as dust, pollen, and pet dander and fur, if you know they cause a reaction in you.
Wash bedding and curtains and clean floors regularly to clear away dust and other triggers.
Use air conditioning at home and in the car to filter allergy-causing particles out of the air.
Eat a healthy diet that supports the immune system and may help reduce your body's response to potential triggers.
Avoid smoking and secondhand smoke, since smoking raises the risk of nasal allergy.
In spring, or whenever you are around your triggers, medical nasal filters can help filter the air you breathe.
Try to keep away from places heavy with dust, exhaust fumes, or strong odors, which can make symptoms worse.
If you already have a history of allergic rhinitis, it is worth seeing an allergy specialist to assess your situation and guide you toward the right treatment.
If your doctor has prescribed treatment to control your symptoms, follow it regularly and exactly as prescribed.
Stress can make allergy symptoms worse, so try to ease it with relaxation techniques such as yoga or meditation.

With an assessment by the specialist team at Town Hospital, the symptoms of allergic rhinitis can be brought under control and your quality of life improved. Allergy is controlled rather than cured, and the plan that fits your case is the one a specialist identifies after examining you.

Frequently Asked Questions

What types of allergy pills are used for nasal allergy and sneezing, and how do they differ?

The medications most often taken by mouth for nasal allergy are the antihistamines, and they come in two generations worth telling apart. The older, sedating generation settles sneezing, runny nose, and itching well, but it causes drowsiness and slows concentration, and that sedation can carry over into the next day even when you do not feel sleepy, which is a real risk if you drive, take exams, or operate machinery. It can also cause dry mouth and difficulty passing urine (urinary retention), make glaucoma and an enlarged prostate worse, and cause confusion and falls in older adults. The newer, non-sedating generation is far less likely to make you drowsy and lasts through the day, but less is not the same as none. A separate class, the leukotriene receptor antagonists, is usually kept for people whose allergy comes alongside asthma; it is not the first choice for nasal allergy on its own because it is weaker than an intranasal corticosteroid spray, and it carries an official warning about changes in mood, behavior, and sleep, and in some cases thoughts of self-harm, so it is not something to take without follow-up. There are also tablets that combine an antihistamine with a decongestant; these raise blood pressure and speed up the heart rate, and they are not an option for many people. And all of these pills do very little for a blocked nose. Which one fits you is a medical decision, not a guess.

What is the best medicine for allergic rhinitis?

The honest answer is that no single medicine suits everyone, and anyone who tells you otherwise is oversimplifying. Your doctor builds the plan around several things: which symptom dominates for you, sneezing with a runny, itchy nose, or constant blockage with a change in your voice and a weaker sense of smell; whether the allergy lasts a short season or runs all year; your age; whether you are pregnant or breastfeeding; whether you have asthma, high blood pressure, a heart condition, glaucoma, or an enlarged prostate; and what other medicines you take, because of interactions. Some people need allergen immunotherapy rather than a daily medicine, and that is not a quick fix: a specialist decides on it after allergy testing, it takes years of regular treatment, and it carries a risk of an allergic reaction, so it is given under medical supervision and not at home. Saline nasal irrigation is a gentle, safe support, as long as you use a ready-made solution or water that has been boiled and left to cool, not water from the tap. All of this is worked out with an ENT doctor, especially if you have blockage on one side only that will not clear, blood in the discharge, a loss of smell that does not come back, facial pain with fever, or shortness of breath, because those may not be ordinary allergy. Straightforward seasonal allergy, on the other hand, is usually easy to bring under control.

When are nasal sprays used, and what is the difference between the types?

An important warning first: decongestant nasal sprays open the nose within minutes, which is exactly what tempts people into leaning on them, and exactly why they are dangerous. Used beyond a few consecutive days, they cause rhinitis medicamentosa: the nose blocks up again, and worse, the moment the effect wears off. That is called rebound congestion, and it can go as far as damaging the lining of the nose. People misread it as the allergy getting worse, so they use more spray, and they end up in a cycle of dependence that is hard to break out of alone and that can run for months. They are sold over the counter here, which is why this happens so often; whether this type is used at all, and for how long, is a decision for the doctor. This warning is about that type only, not about the steroid nasal spray and not about saline. The steroid nasal spray, an intranasal corticosteroid, is the backbone of treatment for persistent allergic rhinitis: it calms the inflammation inside the nose itself. Its effect is not immediate; it takes days to weeks before it shows fully, which is why it is used regularly, on a plan the doctor sets, and not only on bad days. Many people stop it early and decide it is not working when in fact it was still taking effect. Its most common side effects are dryness and light bleeding, and both become less likely when the spray is aimed outward, away from the nasal septum. There are also intranasal antihistamine sprays and combination sprays, and the doctor is the one who decides what suits you. Saline spray is simply a rinse, a safe support. Children, pregnant and breastfeeding women, and anyone with raised pressure inside the eye must ask a doctor before using any spray.

What is the difference between allergic rhinitis and sinusitis?

Both cause cold-like symptoms and a blocked nose, which is what confuses people, but there are practical differences you can notice. Allergic rhinitis brings itching in the nose, the eyes, and the roof of the mouth, sneezing in bursts, and clear watery discharge, and it usually starts quickly once you are exposed to the trigger, such as house dust, pollen, or animal dander, and eases when you get away from it; but if the trigger is around you all year, as house dust is, the symptoms can stay continuous. Sinusitis, by contrast, brings pain or pressure in the face, around the eye or in the cheeks or forehead, thick discharge, a temporary drop in the sense of smell while the inflammation lasts, and fever and exhaustion, especially with an acute infection, and it often follows a cold and then fails to improve after about ten days, or improves and gets worse again. Note that yellow or green discharge is not on its own proof of a bacterial infection, because it happens in ordinary viral colds too. The two also occur together very often, because uncontrolled allergy leaves the lining of the nose swollen and blocks sinus drainage. The real distinction is made by examination, looking inside the nose and asking about the pattern and duration of the symptoms, not from a page on the internet.

When does allergic rhinitis become chronic, and when is it a reason to see a doctor?

Doctors classify it by duration: intermittent, meaning symptoms on fewer than four days a week or for less than four weeks in a row; and persistent, meaning chronic, anything beyond that. There is also a classification by severity, based on the effect on your sleep, your concentration, and your work. If your case is persistent, or it is affecting your sleep and your work, or it is not responding to the plan you are following, that alone is reason to be examined rather than treat yourself. And some signs call for an ear, nose, and throat doctor: blockage of one nostril only that will not clear, repeated bleeding from the same nostril or discharge mixed with blood, or a complete loss of smell or a clear reduction that persists even after the nose opens up, while the mild reduction you get while you are blocked does happen in ordinary allergy. These do not necessarily mean something serious, but they need an examination so the doctor can rule out other causes. And a few situations are rare but urgent: swelling or redness around the eye, a change in vision or double vision, or a severe headache with a high fever, and these need immediate assessment. A persistent cough, shortness of breath, or wheezing in the chest also needs assessment, because nasal allergy and asthma go together.

What types of treatment are used for allergic rhinitis, and what does each one do?

This is general education only, and the choice between these types is a medical decision built on the pattern of your symptoms, your age, your other conditions, and pregnancy if it applies; it is not something to try on your own. Antihistamines reduce itching, sneezing, and watery discharge, but they are weak at opening the blockage itself; the older generations bring on drowsiness and affect concentration, driving, and studying, and they carry warnings for people with glaucoma or an enlarged prostate, while the newer generations are far less sedating, though not sedation-free for everyone. Intranasal corticosteroid sprays work on the inflammation itself and help with the blockage as well, their full effect takes days rather than minutes, and they act in the nose itself, which is not the same as taking a corticosteroid by mouth or by injection; their side effects include dryness or slight bleeding if the spray is aimed toward the nasal septum. Leukotriene receptor antagonists are a medical choice in particular situations, especially when asthma is present, and they carry a known warning about changes in mood, sleep, and behavior. Saline nasal irrigation is safe, cleans the nose, and helps the rest of the treatment work better, provided the water is sterile or has been boiled and left to cool, never straight from the tap, and provided the device is cleaned properly.

Why can't I keep using a spray or drops that open the nose?

This is the most important practical point in the whole subject. Topical decongestants, the spray or drops that open the nose within minutes, narrow the blood vessels in the lining of the nose and so clear the blockage quickly, but they do not treat the allergy at all, and they do nothing for the itching or the sneezing. The problem is that continuing to use them makes the blockage worse rather than better: the lining of the nose swells again, and more severely, as soon as the effect fades, so the person uses more and repeats it and enters a cycle called rebound congestion, or rhinitis medicamentosa, in which the blocked nose is now caused by the spray itself rather than by the allergy. Because they are sold over the counter here, this happens often, with people staying on them for months without follow-up. This warning is specific to the topical type, spray or drops. The type taken by mouth has a different problem: it raises blood pressure, speeds up the heart rate, and disturbs sleep, and it carries warnings for people with high blood pressure, heart disease, thyroid disease, an enlarged prostate, or glaucoma, and it is not suitable for young children. Both of these types are used only on a medical decision, and the doctor is the one who sets the duration.

Can I get rid of allergic rhinitis for good?

Let us be honest with you: allergic rhinitis is not a germ that a course of treatment kills off and finishes. It is a predisposition in the immune system that makes your body treat ordinary things as a danger, such as house dust, pollen, animal dander, cockroaches, and the mold that forms with damp. That predisposition is controlled, not eliminated, but good control can give you long stretches with almost no symptoms, and that is a realistic goal. In practice: find out what specifically sets your allergy off and cut down your exposure to it, bearing in mind that reducing exposure on its own is rarely enough, especially with house dust. Sticking to the plan the doctor has set matters, because some treatments are meant to continue and some are meant to stop early, and that difference is a medical decision. And if your symptoms come with a change in the weather or with strong smells but without itching or sneezing, it may not be allergy at all. Only one approach works on the root of the problem rather than on the symptoms, and that is allergen immunotherapy, but it takes years rather than months, it is done under medical supervision because an allergic reaction is possible, it does not suit every case, and the decision is made only after the type of allergy has been precisely identified. It is not something you start on your own.
