Avapro (generic: irbesartan) is a prescription medication used to treat high blood pressure and diabetic nephropathy (kidney disease). Avapro belongs to a group of drugs called angiotensin II receptor blockers (ARBs), which block the action of angiotensin II, a natural substance that causes blood vessels to contrict (tighten). This helps blood vessels to relax, lowering blood pressure and enabling the heart to pump more efficiently.

This medication comes in tablet form and is usually taken once a day, with or without food, with a full glass of water.

Common side effects of Avapro include diarrhea, heartburn, or dizziness.
