I take one 25mg Benadryl pill every night during the spring (it helps me with allergies at night). But tonight I also took 2 Tylenol PM pills for some back pain without realizing they also had 25mg of diphenhydramine hcl in them as well. Should I be concerned?
-I feel I need to specify that this is not a daily occurrence.
