Common Use
Benicar (olmesartan medoxomil) is a prescription medication used to treat high blood pressure (hypertension). It belongs to a group of drugs called angiotensin II receptor blockers (ARBs). Benicar helps relax blood vessels so that blood can flow more easily, reducing strain on the heart and lowering the risk of stroke, heart failure, and kidney damage, especially in people with diabetes.
Dosage and Direction
Benicar is usually taken once daily, with or without food. The initial recommended dose for most adults is 20 mg per day. Depending on response, the dose may be increased to 40 mg daily. It is important to take Benicar at the same time each day. Swallow the tablet whole with water and do not crush or chew it. Follow your doctor’s directions exactly, and do not adjust the dose without medical advice.
In some cases, Benicar may be combined with other antihypertensive agents. Your doctor will decide the best course of treatment based on your condition.
Precautions
Before starting Benicar, tell your doctor if you have kidney disease, liver problems, heart failure, or dehydration. This medicine can affect electrolyte balance and kidney function. It may cause dizziness, especially during the first few days of treatment. Rise slowly from sitting or lying positions to reduce the risk of falling.
Benicar should not be used during pregnency. It may harm the unborn baby, especially during the second and third trimesters. If you become pregnant, stop taking this medication and notify your doctor right away.
