Irbesartan 150mg tablets are a blood pressure medicine used to treat hypertension. Each tablet contains 150mg of irbesartan, a kind of angiotensin II receptor blocker (ARB). A healthcare practitioner will establish the optimal dosage and duration of irbesartan medication. Irbesartan 150mg tablets are routinely used to treat hypertension and can be used alone or in conjunction with other antihypertensive drugs. Lowering high blood pressure can help minimise the chance of having a heart attack, stroke, or other cardiovascular issues.
