Cozaar (losartan) prescription available online

Losartan belongs to a class of drugs called angiotensin II receptor antagonists (ARB blockers), which prevent blood vessels from narrowing. Angiotensin receptor blockers help lower blood pressure and improve blood flow.

Some conditions that losartan is known to treat include high blood pressure (hypertension), diabetic nephropathy, and left ventricular hypertrophy. Losartan is available only by prescription. It is available in a generic formulation under different brand names, including Cozaar.

Losartan may be prescribed as a tablet or liquid suspension. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage prescribed.

If you're prescribed losartan, be sure to take the angiotensin receptor blockers as directed unless your doctor specifically tells you to stop. If you don’t take your prescription as directed, the angiotensin receptor blockers may not adequately treat your high blood pressure, diabetic nephropathy, or left ventricular hypertrophy.

Losartan has many possible drug interactions. Don’t change what you take without checking with your doctor or pharmacist. That includes other medications, nonprescription drugs, and herbal products.

Possible drug interactions with losartan include:

• Diuretics, or "water pills"

• Other antihypertensive agents

• Lithium

• Nonsteroidal anti-inflammatory drugs (NSAIDs)

Avoid taking potassium supplements or eating high-potassium foods without talking to your doctor. Avoid consuming grapefruit or grapefruit juice while taking losartan.

Ask your doctor for medical advice before drinking alcohol. Alcohol can cause heart rhythm problems when mixed with Cozaar.
