A member asked:
Can i safely take cetirizine or any antihistamine after drinking alcohol? for exemple in case of allergic reaction right after/during a party?
A doctor has provided 1 answer
Usually: but the older antihistamines (Benadryl (diphenhydramine) (diphenhydramine) etc) tends to cause additive drowsiness effect to alochol. A rule of thumb is that a Benadryl (diphenhydramine) 25 mg= 1 shot of alcohol in sedation. The newer ones don't have this issue.
