Answer: No, the package insert should tell you how many you can safely take. And I can advise you right here and now if it is Diphenhdramine Hydrochloride- this is Benadryl. 50mg, of Benedryl is the maximum oral does we give in the emergency room. So please just take one. Otherwise see your doctor for something for sleep, if your having a difficult time sleepingThe bottle may say 50mg...But when you take them and have a light head the next day you know that they are more then 50mgs.Only a drug addict will take pills like that. Be smart and think before you take any pills. Talk to your family doctor.
