Have allergy. i took benadryl (diphenhydramine) 25 mg. after another hour eye was still itchy and nose was really funny and stuffy i took 2 after that is that bad.?

No: You should always adhere to the product dosing instructions. Having said that, the maximum safe dose in 24 hours is 300mg, or no more than 12 capsules or tablets per day. As for your dose taken, i presume you too the second two tablets an hour or so after the first one. Your total is 75mg which be okay. On another note, if your eyes itch, try zaditor™ eye drops, which are over the counter.
