In brief: Benadryl (diphenhydramine) use

Benadryl (diphenhydramine) effects typically last 6-8 hrs.
However; some persons can be adversely effected for much longer. To be safe, don't drink within 24 hrs of using any sedating antihistamine. All antihistamines are potentially sedating, indivdual senstivities to side-effects vary greatly.
