A member asked:
Hi, i have allergic rhinitis and asthma, since my allergies are very strong i drink allegra daily can i take benadryl (diphenhydramine) at night?
A doctor has provided 1 answer
Yes: one dose of benadryl (diphenhydramine) at night (25mg) is safe. However use it only when absolutely necessary. Antihistamine overdose can make you dehydrated, have a fast heart rate and feel anxious.
