What is Irbesartan?
Irbesartan is an angiotensin II receptor blocker (ARB) that treats high blood pressure by relaxing blood vessels. This medication helps prevent strokes, heart attacks, and kidney problems by reducing strain on your cardiovascular system. Irbesartan works by blocking the action of angiotensin II, a substance in your body that causes blood vessels to tighten and narrow.

Missed Dose
If you miss a dose of Irbesartan, take it as soon as you remember. However, if it’s almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule.
