Is it safe to take 2 25mg bendryl every night?

Diphenhydramine. You may take up to 50mg at night preferably. It is very sedating since it is one of the old antihistamines.....Nevertheless very effective. Do not combine with other drugs such as alcohol. Do not take if you are in the geriatrics population. You're only 19 y/o old though. Should be ok. It will allow you to fall asleep. It can however (rarely cause paradoxical agitation and confusion).Use carefully.
