A member asked:

Is there any side effects when you take antihistamines for a longer period than a month?

A doctor has provided 1 answer
Dr. Lee Perry answered

Unlikely: Antihistamines are generally safe to take for prolonged periods of time, as long as you're taking the proper dose. These medicines are notorious for causing drowsiness, although some over the counter antihistamines are non-drowsy.
