Losartan is a prescription medication mainly used to treat high blood pressure. It is also used for diabetic kidney disease, heart failure, and left ventricular enlargement. It is taken by mouth. It may be used alone or in addition to other blood pressure medication.
Losartan is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure may reduce the risk of strokes and heart attacks.
Losartan is an angiotensin II receptor blocker (ARB). It works by blocking a substance in the body that causes blood vessels to tighten. As a result, losartan relaxes the blood vessels. A lower blood pressure will increase the supply of the blood and oxygen to the heart.
Losartan is also used to decrease the risk of stroke in patients with high blood pressure and enlargement of the heart. It is also used to treat kidney problems in patients with type 2 diabetes and a history of hypertension.
How should Losartan be used?
Losartan comes as a tablet to take by mouth. It is usually taken once or twice a day with or without food. To help you remember to take losartan, take it at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take losartan exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of losartan and gradually increase your dose.
If your child can not swallow a tablet, talk to your doctor or pharmacist. The pharmacist can prepare a liquid form of this medication for your child.
Losartan controls high blood pressure but does not cure it. Your blood pressure may decrease during the first week of your treatment, but it may take 3 to 6 weeks for you to notice the full benefit of losartan. Continue to take losartan even if you feel well. Do not stop taking losartan without talking to your doctor.
Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.
