Allergic Rhinitis & Runny Nose
Repeated sneezing and a blocked or runny nose deserve more than guessing which tablet to take. Identify the pattern and build a plan for better day-to-day control.
What is allergic rhinitis?
Allergic rhinitis is inflammation inside the nose triggered by an immune reaction to an allergen, such as dust mites, pollen, mould or animal dander. Typical symptoms include sneezing, a runny or blocked nose, nasal itching and itchy, watery eyes. Symptoms may be seasonal or recur throughout the year, depending on exposure.

Is a runny nose always an allergy?
No. A cold, irritants and non-allergic rhinitis can produce similar nasal symptoms. Repeated itching and sneezing after a particular exposure can suggest allergy, while fever and general illness make infection more likely. Smoke, temperature changes and some medicines can trigger non-allergic symptoms. The pattern over time is often more useful than one symptom alone.
How does a GP identify likely triggers?
Bring a short record of when symptoms occur: at home, at work, around pets or after cleaning. Mention sleep disturbance, wheezing and the medicines or nasal sprays you use. Kauri starts with your history and examination. Allergy blood testing can help answer a specific question when indicated, but a panel is not necessary for every runny nose and a positive result must fit your symptoms.

What treatments can improve control?
Depending on the cause, treatment may include reducing relevant exposure, antihistamines, a steroid nasal spray or saline care. The choice and technique matter: a spray used incorrectly may not help as expected. Some decongestant sprays can worsen congestion when used too long. Your doctor reviews what you have tried and explains how to use the selected treatment.
What if symptoms keep coming back?
Review persistent symptoms rather than repeatedly switching products. Ongoing triggers, technique, non-allergic inflammation or another nasal condition may explain incomplete relief. Follow-up can refine the diagnosis and treatment. Tell the clinician if symptoms mainly affect one side, disturb sleep or are accompanied by recurrent bleeding.

Common questions
Do I need an allergy blood panel before treatment?
Not always. Many nasal symptoms can first be assessed through history and examination. Testing is most useful when it answers a specific question that could change your management.
Can allergies be present all year in Bangkok?
Yes. Indoor exposures such as dust mites or animal allergens can occur year-round. Your personal exposure pattern matters more than assuming every episode is seasonal.
Can a nasal spray make a blocked nose worse?
Some decongestant sprays can cause rebound congestion if used longer than directed. This is not the same as every nasal spray. Bring the product so the doctor can check it.
