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
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.

Why do I get an itchy red flushing rash when I get hot or am in a hot environment for even short (less than 30) periods of time. What could cause this?? Allergy meds (Benadryl and Vistaril) stop the itching but I still have red and hot skin for hours
