A member asked:
Are fexofenadine hcl and diphenhydramine hcl the same?
A doctor has provided 1 answer
No: Benadryl (diphenhydramine) is a short-acting antihistamine and is more likely to make you sleepy when used. Fexofenadine is a second-generation, non-sedating antihistamine which should have more lasting effects, closer to 24 hours, and is less likely to make you sleepy.
