Hi, I have allergic rhinitis and asthma, since my allergies are very strong I drink allegra daily can i take benadryl (diphenhydramine) at night?

In brief: 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.
