Long term?: Benadryl (diphenhydramine), (diphenhydramine) the brand for Diphenhydramine is a relatively safe drug. It can cause drowsiness, so it is best taken at bedtime. Many people do take it for allergies and other conditions during the day. The is not too much information on taking Benadryl (diphenhydramine) for the long term. I recommend taking the least effective amount possible and possible seeing an allergist to further diagnose you.

Allergy specialist: Recommend allergy evaluation if you are not able to identify the cause and avoid it. Allergy prophylaxis with otc medications till then.
