A member asked:
How long should one take benadryl (diphenhydramine) for hives before seeing a dr?
A doctor has provided 1 answer
As soon as you feel: You are obviously reacting to something. Trying to isolate what is causing hives and removing it from your diet/environment/exposure is probably goal #1. Benadryl (diphenhydramine) or other anti-histamines treat symptoms but do not treat the problem.
