Allergic rhinitis, commonly known as hay fever, can cause persistent sneezing, a runny or blocked nose, nasal itching and watery eyes, affecting your sleep, concentration and daily comfort. It occurs when the immune system reacts to allergens such as dust mites, pollen, mould or animal dander. Although these symptoms may resemble a common cold, allergic rhinitis can continue for weeks or recur throughout the year.
At ENT Clinic of Excellence in Dubai Healthcare City, patients experiencing persistent nasal congestion, sneezing or difficulty breathing through the nose can receive an ENT assessment to help identify the cause of their symptoms and discuss appropriate treatment options.
In this guide, we explain allergic rhinitis symptoms, common triggers, diagnosis, treatment options and when to consult an ENT specialist in Dubai.
What Is Allergic Rhinitis?
Allergic rhinitis is inflammation of the lining inside the nose caused by an allergic response to substances in the environment. When a person with an allergy inhales a trigger, the immune system releases chemicals, including histamine, that cause irritation, swelling and increased mucus production.
This reaction can lead to repeated sneezing, nasal congestion, itching and a runny nose. Some people also experience itchy eyes, throat irritation or mucus dripping down the back of the throat, known as post-nasal drip.
Allergic rhinitis is not an infection and is not contagious. However, its symptoms can interfere with sleep, work, school and everyday activities.
For additional medical information, read the NHS guide to allergic rhinitis.
What Are the Common Symptoms of Allergic Rhinitis?
The symptoms of allergic rhinitis may begin within minutes of exposure to an allergen. Their severity varies depending on the individual, the trigger and the degree of inflammation.
Common allergic rhinitis symptoms include:
- Frequent sneezing: Repeated sneezing, particularly after exposure to dust or other allergens.
- Runny nose: Thin, watery nasal discharge.
- Nasal congestion: Swelling inside the nose that makes breathing difficult.
- Nasal itching: An itchy feeling inside the nose that may lead to repeated rubbing.
- Watery or itchy eyes: Eye irritation, redness and tearing.
- Post-nasal drip: Mucus running down the back of the throat, sometimes causing coughing or throat clearing.
- Reduced sense of smell: Persistent nasal inflammation may interfere with the ability to smell normally.
- Sleep disturbance and fatigue: Nasal blockage can make restful sleep more difficult.
Some patients experience several symptoms simultaneously, while others mainly notice a persistently blocked nose.
If nasal congestion continues despite treatment, an ENT examination can help determine whether allergies are the only cause or whether another problem, such as a deviated nasal septum, enlarged turbinates or nasal polyps, may also be contributing.
What Causes Allergic Rhinitis in Dubai?
Allergic rhinitis develops when a person’s immune system reacts to an otherwise harmless substance. In Dubai, exposure to indoor allergens and environmental irritants may contribute to nasal symptoms, although the specific trigger varies from person to person.
Common triggers include:
1. House Dust Mites
Dust mites are microscopic organisms commonly found in mattresses, pillows, upholstered furniture and carpets. Their particles can trigger allergic symptoms in sensitive individuals.
2. Dust and Airborne Particles
Dust and airborne particles may irritate the nose. Some people have a genuine allergic response to particular particles, while others experience non-allergic irritation. These conditions can produce similar symptoms but may require different management.
3. Mould
Mould releases microscopic spores that can trigger allergic reactions. Damp areas, water-damaged materials and poorly maintained indoor spaces may encourage mould growth.
4. Pollen
Pollen from trees, grasses and weeds is a common cause of seasonal allergic rhinitis. Symptoms depend on the types of pollen present and an individual’s sensitivity.
5. Pet Dander
Proteins found in animal skin flakes, saliva and other secretions can trigger symptoms in people who are allergic to cats, dogs or other animals.
6. Air Conditioning and Dry Indoor Air
Air conditioning is essential for comfort in Dubai, but poorly maintained filters, accumulated dust and dry indoor air can aggravate nasal irritation in some people.
Air conditioning itself does not necessarily cause an allergy. It is important to distinguish allergic rhinitis from irritation caused by dry air, strong fragrances, cleaning products or other environmental factors.
What Is the Difference Between Allergic Rhinitis and a Common Cold?
Allergic rhinitis and a common cold can both cause sneezing, nasal discharge and congestion. However, certain features can help distinguish them.
| Feature | Allergic rhinitis | Common cold |
|---|---|---|
| Main cause | Reaction to allergens | Viral infection |
| Sneezing | Often frequent | May occur |
| Nasal itching | Common | Less typical |
| Itchy, watery eyes | Common | Less typical |
| Fever | Not caused by allergic rhinitis itself | Sometimes present |
| Duration | Can persist or recur with exposure | Usually improves over several days to around 1–2 weeks |
| Pattern | May recur around specific triggers | Usually follows a temporary course |
These differences are not absolute. A clinical assessment may be needed when symptoms are persistent, unusual or difficult to distinguish.
How Is Allergic Rhinitis Diagnosed?
Diagnosing allergic rhinitis involves understanding the patient’s symptoms, medical history and possible exposure to allergens.
During an ENT consultation, Dr. Hatem Dalati, ENT Consultant and Rhinoplasty Surgeon at ENT Clinic of Excellence, can assess persistent nasal symptoms and investigate whether nasal inflammation or structural problems may be contributing to breathing difficulties.
Depending on the patient’s presentation, an assessment may include:
- Medical history: When symptoms occur, how long they last and whether they are associated with dust, pets, particular environments or other triggers.
- Nasal examination: Assessing the nasal lining, swelling, discharge and visible structural abnormalities.
- Nasal endoscopy: A small camera may be used when indicated to examine deeper areas of the nasal passages and look for conditions such as nasal polyps.
Not every patient requires every test. The appropriate investigation depends on the symptoms and clinical findings.

What Is the Best Treatment for Allergic Rhinitis?
The best allergic rhinitis treatment depends on symptom severity, the suspected triggers, the patient’s medical history and response to previous treatment. Management often combines reducing exposure to allergens with appropriate medication.
1. Reduce Exposure to Allergens
Avoiding or reducing exposure to identified triggers can help control symptoms.
Practical steps include:
- Wash bedding regularly and consider dust-mite-resistant mattress and pillow covers if dust mites are a suspected trigger.
- Clean surfaces using a damp cloth to reduce airborne dust.
- Vacuum regularly, preferably with a suitable high-efficiency particulate air (HEPA) filter.
- Address dampness and visible mould in indoor spaces.
- Keep bedroom windows closed when outdoor allergens are a problem.
- Clean and maintain air-conditioning filters according to the manufacturer’s recommendations.
- Avoid cigarette smoke, strong fragrances and other irritants that worsen symptoms.
It may not be possible to avoid every allergen, but identifying the most relevant triggers can make a difference.
2. Antihistamines
Antihistamines reduce the effects of histamine, a chemical involved in allergic reactions. Depending on the medication, they may help relieve sneezing, nasal itching, a runny nose and itchy eyes.
They are available in different forms, including tablets, liquids, eye drops and nasal sprays.
Some antihistamines can cause drowsiness. A healthcare professional or pharmacist can help you choose an appropriate option based on your symptoms, age, other medications and medical history.
3. Corticosteroid Nasal Sprays
Intranasal corticosteroids reduce inflammation inside the nose and are among the most effective treatments for persistent allergic rhinitis, particularly when nasal congestion is prominent.
They generally work best when used regularly as directed. Their full benefit may take several days or longer to develop, so correct technique and consistent use are important.
To use a nasal spray correctly, follow the product instructions and aim the nozzle slightly outward, away from the nasal septum. Avoid forceful sniffing after spraying.
Discuss persistent irritation, recurrent nosebleeds or uncertainty about the correct technique with your healthcare professional.
4. Saline Nasal Rinses
Saline sprays or nasal rinses may help remove mucus, dust and allergens from the nasal passages. They can be used as an additional measure alongside other treatments when appropriate.
For nasal irrigation, use sterile, distilled or previously boiled and cooled water, and follow the device’s cleaning instructions. Do not use untreated tap water for nasal rinsing.
5. Allergen Immunotherapy
For selected patients with confirmed allergies and persistent symptoms, allergen immunotherapy may be considered following specialist evaluation.
This treatment involves controlled exposure to specific allergens over time, usually through injections or selected sublingual products. It is designed to modify the allergic response rather than provide only temporary symptom relief.
Immunotherapy is not suitable for everyone and requires an individual assessment.
6. When Is Surgery Considered?
Allergic rhinitis is generally managed medically rather than with surgery because an operation does not remove the underlying allergic tendency.
However, some patients have additional structural problems that contribute to persistent nasal obstruction, such as a deviated septum, enlarged inferior turbinates or nasal polyps.
In these cases, an ENT specialist may discuss whether a procedure could help address the structural component of the blockage. Treatment of the allergy itself may still be necessary after surgery.

Can Allergic Rhinitis Cause a Blocked Nose All the Time?
Yes. Persistent allergic inflammation can cause swelling of the nasal lining and enlargement of the inferior turbinates, the structures inside the nose that help warm and humidify inhaled air.
When these tissues swell, the nasal passages become narrower, making breathing through the nose more difficult. Symptoms may be worse at night or after exposure to a trigger.
However, chronic nasal obstruction is not always caused by allergies. Other possible causes include a deviated septum, chronic rhinosinusitis, nasal polyps and non-allergic rhinitis.
If one side of your nose remains persistently blocked, symptoms are progressively worsening, or treatment does not help, arrange a medical assessment. Persistent one-sided blockage, particularly when accompanied by bleeding or bloody discharge, should be evaluated promptly.
When Should You See an ENT Specialist in Dubai?
Occasional sneezing or a mild runny nose may be manageable with appropriate advice and treatment. However, a specialist assessment is advisable if:
- Nasal congestion persists or repeatedly returns.
- Symptoms interfere with sleep, concentration or daily activities.
- You frequently breathe through your mouth because your nose feels blocked.
- You experience reduced smell or persistent post-nasal drip.
- You have recurrent sinus symptoms or pressure.
- Pharmacy treatments have not provided sufficient relief.
- You are unsure whether your symptoms are caused by allergies or a structural nasal problem.
- You have asthma and your respiratory symptoms are worsening.
Seek urgent medical attention for severe breathing difficulty or swelling of the lips, tongue or throat.

Frequently Asked Questions About Allergic Rhinitis
1. Is allergic rhinitis common in Dubai?
Allergic rhinitis can affect people living in Dubai, as in other regions. Indoor dust mites, mould, pollen and animal allergens may trigger symptoms. The relevant trigger varies between individuals, so persistent symptoms should be assessed rather than automatically attributed to dust or air conditioning.
2. Can allergic rhinitis be cured permanently?
There is no single treatment that permanently eliminates allergic rhinitis in every patient. Many people can control their symptoms with allergen avoidance, medication and appropriate follow-up. Allergen immunotherapy may provide longer-term benefits for selected patients.
3. What is the most effective treatment for allergic rhinitis?
Intranasal corticosteroid sprays are among the most effective options for persistent symptoms, particularly nasal congestion. Antihistamines and saline rinses may also help. The most appropriate treatment depends on symptom severity, medical history and individual response.
4. Can allergic rhinitis cause mouth breathing?
Yes. When allergic inflammation causes significant nasal congestion, a person may breathe through the mouth, especially during sleep. Persistent mouth breathing should be assessed because structural obstruction and other nasal conditions can produce similar symptoms.
5. Can allergic rhinitis cause sinusitis?
Allergic rhinitis and rhinosinusitis are different conditions, but they can coexist. Nasal inflammation may contribute to impaired nasal and sinus function in some patients. Persistent facial pain, reduced smell or prolonged symptoms may require further assessment to determine whether sinusitis is present.
6. Does air conditioning make allergic rhinitis worse?
Air conditioning does not automatically cause allergic rhinitis. However, accumulated dust in filters, dry air and other indoor irritants may aggravate symptoms in some people. Regular maintenance and identifying individual triggers may help.
7. Can surgery treat allergic rhinitis?
Surgery does not cure the underlying allergy. It may be considered when a separate structural problem, such as a deviated septum or enlarged turbinates, contributes to persistent nasal obstruction. Medical allergy management may still be needed.
8. When should I consult an ENT specialist?
Consider an ENT consultation if symptoms persist, affect sleep or daily life, cause ongoing nasal obstruction, or do not improve with appropriate treatment. Assessment can help identify whether allergies, structural abnormalities or another condition are responsible.
