Tribenzor (generic: olmesartan/amlodipine/hydrochlorothiazide) is a prescription medication used to treat high blood pressure. It is a single tablet containing 3 medications, olmesartan, amlodipine, and hydrochlorothiazide. Olmesartan, an angiotensin II receptor blocker (ARB), and amlodipine, a calcium channel blocker, both work by relaxing veins and arteries so that blood can more easily pass through them. Hydrochlorothiazide belongs to a group of drugs called diuretics ("water pills"), which help the body get rid of excess fluid.

This medication comes in tablet form and is taken once a day, with or without food.

Common side effects of Tribenzor include swelling, headache, nausea, and diarrhea. Tribenzor can cause dizziness or drowsiness. Do not drive or operate heavy machinery until you know how Tribenzor affects you.
