A member asked:
Are doses of cetirizine (reactine) 20mg bid too high for a period of 6 months. could you link any studies about that dosage for long periods of time.
A doctor has provided 1 answer
Ok: Anthistamine has a very high safety margin. In fact many of our patients with chronic hives have been taken cetirizine in the dose mentioned for years without any problem. The major side effects would be drowsiness and dry mouth.
