Took dye free Benadryl (diphenhydramine) to help w headache, broke into 3 or 4 hives after taking it. Is this Benadryl (diphenhydramine) alrgy & can I be desensitized?

In brief: Doubt it

It is possible but highly unlikely to be from Benadryl (diphenhydramine) allergy.
However there are so many other antihistamines to choose , it would not be necessary to get desensitized to Benadryl (diphenhydramine) even if you were allergic to it.
