Choosing the Right Antihistamine: A Doctor's Perspective
What are antihistamines?
There are two main groups: non-drowsy (cetirizine, loratadine, fexofenadine) and sedating (chlorphenamine, promethazine). Sedating types may also be used short-term for sleep or motion sickness.
When to seek medical advice
Speak to a pharmacist for everyday allergies. See a GP if symptoms are severe, not improving with standard doses, or if you need long-term treatment.
Available treatments
Most antihistamines are available without prescription. Higher-strength versions, such as fexofenadine 180 mg, require a prescription. They come as tablets, liquids, nasal sprays and eye drops.
What to expect
Non-drowsy options work within an hour and last 24 hours. Sedating types start within 30 minutes but cause drowsiness and may impair driving.
Self-care
Identify and avoid triggers, use saline nasal rinses, vacuum regularly if dust mite allergic, and start treatment before allergy season begins.
