What is Benicar (Olmesartan)?

Benicar is a medication prescribed to treat high blood pressure (hypertension) in adult patients and children 6 years and older.

Benicar belongs to the drug class, angiotensin receptor blockers (ARBs). This medication works by keeping the blood vessels from narrowing, which lowers blood pressure. This allows more blood and oxygen to get to your heart and other organs and helps your heart not to work as hard.

Benicar is not recommended:

  • If you are allergic or have had an allergic reaction to Benicar or ingredients in Benicar
  • If you are pregnant or breastfeeding
  • For children under 6 years of age, especially those below 1 year old

What are the Indications for Benicar?

Benicar is approved to treat high blood pressure. While lowering blood pressure can also reduce the risk of strokes, heart attacks, and kidney problems, it is not specifically approved for these conditions.
