A member asked:
Hydroxyzine and benadryl (diphenhydramine) both give me similar horrible side effects, but doxylamine does not, is there a reason for this?
A doctor has provided 1 answer
Yes: Both Hydroxyzine and Benadryl (diphenhydramine) are highly sedating for people, while doxylamine has less sedating effect. The newer antihistamines have very low or no sedating effects.
