 [ Symptoms ] i have just turned 40 and have advanced glaucoma started having confused episodes [ Disease ] this is a great question tylenol pm is actually not recommended in pregnancy because of the fact that not only does it contain tylenol but it contains an antihistamine like benadryl or diphenhydramine and that is really not recommended for use in pregnant moms so you want to avoid that tylenol is actually the safest pain reliever to use in pregnant women but i want to make sure that you use it for short term used only and if you are going to take it make sure you check it out with your doctor first and if you have any questions come and ask us
