Allergies can be a real struggle, but the right oral antihistamine can provide fast and effective relief. Based on pharmacist recommendations and sales data, here are the top antihistamines ranked from best to least recommended.
1. Cetirizine (Brand Name: Zyrtec)
Why it’s the best: Cetirizine is a second-generation antihistamine that works quickly (within 30 minutes) and lasts for 24 hours. While it is generally non-drowsy, some users may still experience mild sedation.
2. Loratadine (Brand Name: Claritin)
Why it’s great: Loratadine is a non-drowsy antihistamine effective against hay fever and chronic hives. It does not cross the blood-brain barrier, reducing drowsiness.
3. Fexofenadine (Brand Name: Allegra)
Why it’s effective: Fexofenadine is preferred for its non-drowsy profile, making it ideal for daytime use. It provides relief from allergic rhinitis and chronic idiopathic urticaria.
4. Diphenhydramine (Brand Name: Benadryl)
Why it’s useful: Diphenhydramine is a first-generation antihistamine that works well but causes drowsiness. It is often used as a sleep aid or for severe allergic reactions.
