Is this possible?: a persons body makes antibodies against the active ingredient of generic diphenhydramine, but it does not make antibodies against the active ingredient of brand benadryl?
A doctor has provided 1 answer
Not possible: This isn't possible. The active ingredient is diphenhydramine, the same in both generics and the Benadryl brand.
