Atacand is a prescription medication used to treat high blood pressure in adults and children and certain types of heart failure in adults. Atacand belongs to a group of drugs called angiotensin receptor blockers (ARBs), which prevent blood vessels from narrowing. This relieves the heart from excess strain and allows blood to pump smoothly.

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

Common side effects of Atacand include back pain, sore throat, and nasal congestion. Atacand can also cause dizziness. Do not drive or operate machinery until you know how Atacand will affect you.
