A member asked:
Is promethazine and bynadryl in the same family? i think its what caused my anaflatic shock cus im elerject to benadryl (diphenhydramine). i almost died because of it.

No: And Promethazine is far more likely to cause adverse side effects, aside from drowsiness, than benadryl (diphenhydramine). Please describe the type of reactions you had with Benadryl (diphenhydramine) since I have never heard of an anaphylactic reaction to this drug.
