By the way, doctor: Is it okay to take ibuprofen p.m.?
Q. I take ibuprofen p.m. on occasion — maybe once a month or so — to help me get to sleep. It seems to work. Is that okay?
A. Ibuprofen p.m. is a combination medication that contains ibuprofen and diphenhydramine, which is the active ingredient in Benadryl, an antihistamine taken for allergies.
