Yes.: Benadryl (diphenhydramine) would be safe to take with allegra. Remember not to operate any heavy machinery or drive while taking this medication. It will not affect your blood pressure unless you are taking Allegra-D or the formulation with pseudophedrine.

Benadryl (diphenhydramine) Use: It should be "safe" unless you get too much sedation. Ask your primary care doc then take it only at night when you need to sleep anyway. There are numerous other (possibly more effective) options as well. Check with an ENT or allergy doc.
