Anonymous 31 Oct 2012. Diphenhydramine is benadryl & usually comes in 25 mg doses OTC. You can take 2 safely at a time. The max dose for 24 hours is 300mg, but have never heard of anyone taking this much, & definately not all at once. How many you take at one time also depends on others meds you may take also.
