Olmesartan/hydrochlorothiazide, sold under the brand name Benicar HCT among others, is a medication used to treat high blood pressure. It is a combination of olmesartan, an angiotension receptor blocker and hydrochlorothiazide, a diuretic. It may be used if olmesartan is not sufficient to manage blood pressure. It is taken by mouth.
Common side effects include nausea, dizziness, and upper respiratory tract infections. Serious side effects may include kidney problems, allergic reactions, electrolyte problems and low blood pressure. Use in pregnancy is not recommended. Olmesartan works by blocking the effects of angiotensin II while hydrochlorothiazide works by increasing the loss of sodium by the kidneys.
