A member asked:
Does benadryl (diphenhydramine) raise blood pressure, lower it, or neither??
A doctor has provided 1 answer
Neither: Benadryl (diphenhydramine) has no appreciable effect on BP. It's safe in heart disease. We give it intravenously (much more potent given IV) in the cardiac cath lab routinely.
