Olmesartan/hydrochlorothiazide, sold under the brand name Benicar HCT among others, is a medication used to treat high blood pressure.[1] It is a combination of olmesartan, an angiotension receptor blocker and hydrochlorothiazide, a diuretic.[1] It may be used if olmesartan is not sufficient to manage blood pressure.[2] It is taken by mouth.[2]

Common side effects include nausea, dizziness, and upper respiratory tract infections.[3] Serious side effects may include kidney problems, allergic reactions, electrolyte problems and low blood pressure.[3] Use in pregnancy is not recommended.[3] Olmesartan works by blocking the effects of angiotensin II while hydrochlorothiazide works by increasing the loss of sodium by the kidneys.[3]

No generic version is available in the United States as of 2017.[1] A month supply in the United Kingdom costs the NHS about 13 £ as of 2019.[2] In the United States the wholesale cost of this amount is about US$6.[4] In 2016 it was the 258th most prescribed medication in the United States with more than a million prescriptions.[5]
