yes they can be taken together. there are much better medications for allergies than benadryl which only lasts 4 hours. why not try genertic claritin zyrtec or allegra? they can last a whole day.
can you take tylenol and benedryl together? . i am taking tylenol for my sprained ankle and benadryl for night allergies. i get allergy shots so my allergies have recently gotten worse.
