Which high blood pressure medicine does not cause hair loss or diarrhea?

Diarrhea and hair loss is a reported side effect with several medications that reduce blood pressure. Cozaar has a small percent of hair loss reported, but diarrhea did occur. Furosemide does not seem to cause hair loss, but both constipation and diarrhea have been reported. Furosemide is generally well-tolerated. Hydrochlorothiazide does not seem to cause either hair loss or diarrhea. You need to discuss your options with your physician so that together you can review your medication history and current medical conditions because each blood pressure medication works differently and works on different aspects of the causes of blood pressure.
