Question: can blood pressure medications make you have diarrhea?
Answer: ACE inhibitors and angiotensin receptor blockers (ARBS) are used to treat high blood pressure and heart failure, and all have diarrhea as a reported side effect. The ARB olmesartan (Benicar, Azor) is the biggest offender in this class of drugs and diarrhea can be severe and long lasting while you're taking it.
