Cozaar (active ingredient: losartan) is a prescription medication used to treat high blood pressure (hypertension) and to help protect kidney function in certain people with type 2 diabetes. It belongs to a class of medications known as angiotensin II receptor blockers (ARBs).
By relaxing and widening the blood vessels, Cozaar helps lower blood pressure, improve blood flow, and reduce the workload on the heart.

Cozaar is available as an oral tablet and is typically taken once daily, with or without food. Your dosage will depend on the condition being treated, your response to therapy, and any other medical conditions you may have.
Take Cozaar exactly as prescribed by your healthcare provider. Try to take it at the same time each day to help maintain consistent blood levels and improve blood pressure control.

Cozaar may cause harm to an unborn baby and should not be used during pregnancy, especially during the second and third trimesters. If you become pregnant while taking Cozaar, contact your healthcare provider immediately. They will discuss alternative treatment options and advise whether you should stop taking the medication.
Losartan may also pass into breast milk. If you are breastfeeding or planning to breastfeed, talk to your healthcare provider to determine whether Cozaar is appropriate for you or if another treatment would be safer.
Cozaar may cause:

Seek immediate medical attention if you develop symptoms of an allergic reaction, including:
If you have diabetes, you should generally not take Cozaar together with aliskiren, another medication used to treat high blood pressure, unless specifically directed by your healthcare provider.

Yes. Cozaar may interact with certain medications, which can affect how it works or increase the risk of side effects. Some medications that may interact with Cozaar include diuretics (water pills), nonsteroidal anti-inflammatory drugs (NSAIDs), angiotensin-converting enzyme (ACE) inhibitors, potassium-sparing diuretics, and potassium supplements or salt substitutes containing potassium. Before starting Cozaar, tell your healthcare provider about all prescription medications, over-the-counter products, vitamins, herbal supplements, and natural health products you take. Providing a complete medication list helps reduce the risk of potentially harmful drug interactions and allows your healthcare provider to determine whether any dosage adjustments or additional monitoring are needed.
Cozaar begins lowering blood pressure soon after you start taking it, but it may take several weeks to reach its full therapeutic effect. Some people notice improvements earlier, while others may not experience the full benefits until they have taken the medication consistently for a few weeks. Continue taking Cozaar exactly as prescribed, even if you feel well, and attend regular follow-up appointments so your healthcare provider can monitor your progress.
Yes. Cozaar is generally considered safe for long-term use when taken as prescribed and monitored by a healthcare provider. Many people take Cozaar for months or years to help manage high blood pressure or protect kidney function. Your healthcare provider will periodically monitor your blood pressure, kidney function, and potassium levels to ensure the medication remains safe and effective. Always discuss the potential benefits and risks of long-term treatment with your healthcare provider, and do not stop taking Cozaar without medical advice.
