Irbesartan can cause injury and possibly death to a developing fetus when used during pregnancy. Talk with your doctor at once if you suspect that you are pregnant. If you are planning to become pregnant, talk with your doctor about other treatment options.
Irbesartan is used for:
Treating high blood pressure alone or with other medicines. It is also used in certain patients to treat kidney problems caused by diabetes (diabetic nephropathy). It may also be used for other conditions as determined by your doctor.
Irbesartan is an angiotensin II receptor blocker (ARB). It works by relaxing blood vessels. This helps to lower blood pressure.
Do NOT use irbesartan if:
- you are allergic to any ingredient in irbesartan
- you are pregnant
- you are taking a medicine that contains aliskiren and you also have diabetes or kidney problems. Check with your doctor or pharmacist if you are not sure if a medicine you take contains aliskiren
Contact your doctor or health care provider right away if any of these apply to you.
