Which OTC allergy meds are safe to use with diazepam?

Allegra & Claritin (loratadine) Are both safe to use with diazepam because neither one can make you drowsy. Zyrtec might be ok. Avoid benadryl (diphenhydramine).
Talk to your Doc. All medications have the potential for drug interactions. One should clarify with their doc which rx meds and otc meds can be used together.
