Winter13; No it is not recommended unless a doctor tell's you different normally you should keep it at least 4 to 6 hours apart but if you're not getting much relief from the 50mg at once you really should talk with a doctor you may need something else that works better for whatever your taking it for. Good luck and be careful. Chuck1957
I have taken benadryl many times for allergies in the past, at doses of either 25mg in the daytime, or 50mg at night, when I know it will make me more sleepy. One time I was having an allergic reaction to something I ate and I called my pharmacist, described my symptoms to him, and he recommended for me to take 100mg benadryl this ONE time only. My side effects immediately subsided with this dose, but be prepared to be so sleepy, you have to more than likely lay down and sleep for a while. I would not take that high a dose just for hay fever or allergies of this type (sneezing, runny nose, watery eyes).
