Overview
An allergy happens when the immune system overreacts to something usually harmless, such as pollen, dust mites, pet hair, certain foods or medicines. Common allergies include hay fever (allergic rhinitis), itchy skin rashes (hives) and allergic eye problems. In Lahore, spring pollen (paper mulberry) and winter smog make allergies very common.
Causes
- Pollen from trees and grass
- House dust mites
- Pet dander and mould

Diagnosis
Your doctor will ask about your symptoms and triggers. Skin prick tests or blood tests can help find the cause in some cases.
Management
- Avoiding known triggers; masks on high-pollen and smoggy days
- Antihistamines such as cetirizine, fexofenadine or desloratadine
- Steroid nasal sprays for a blocked nose
- Montelukast in some people, as prescribed
- Keeping windows closed during pollen season
When to see a doctor
See a doctor if allergy symptoms affect sleep or daily life or do not respond to usual medicines. Call emergency help for swelling of the face, lips or throat, difficulty breathing, or feeling faint: this can be anaphylaxis.
