A member asked:

Allegra (fexofenadine) around 7 am,,, can i take a benedryl at night to help me sleep,, ?

A doctor has provided 1 answer

Yes: These two agents do not cross react and benadryl (diphenhydramine) is a very safe anti-allergic medicine which will for most induce sleep as well.

Dr Hegab and another doctor agreed
