🛒 Compare PricesWhat is Losartan?
Losartan is the generic name for the brand drug Cozaar. It belongs to a class of medications called angiotensin II receptor blockers (ARBs). Losartan is FDA-approved to treat high blood pressure (hypertension), reduce the risk of stroke in certain patients with heart problems, and slow the progression of kidney disease in people with type 2 diabetes and high blood pressure.
Losartan works by blocking a natural substance that narrows blood vessels, allowing blood to flow more easily and lowering blood pressure.
What is Losartan Used For?
According to the FDA, losartan is approved to treat:
- ✔️ Hypertension (high blood pressure) – helps lower blood pressure to reduce the risk of stroke and heart attack.
- ✔️ Stroke risk reduction – in patients with high blood pressure and left ventricular hypertrophy (enlarged heart).
- ✔️ Diabetic nephropathy – protects the kidneys in people with type 2 diabetes and high blood pressure.
Doctors may prescribe it alone or with other blood pressure medications. Always follow your prescriber's instructions.
Available Dosages and Forms
Losartan is available as oral tablets in several strengths:
- Tablets: 25 mg, 50 mg, 100 mg
Generic losartan is available in the same strengths and is equally effective, usually at a lower cost.
Brand Cozaar vs Generic Losartan
Both contain the same active ingredient and meet the same FDA standards for quality, safety, and effectiveness. The only significant difference is price: generic losartan is typically much less expensive. Most insurance plans prefer or require generics.
When comparing prices, you may see both options. Choose the one that best fits your budget and prescription.
How to Take Losartan Safely
Always follow your healthcare provider's instructions. Losartan is usually taken once or twice daily, with or without food.

- If you miss a dose, take it as soon as you remember unless it is close to your next dose.
- Do not take a double dose to make up for a missed one.
- Avoid potassium supplements or salt substitutes containing potassium unless your doctor tells you otherwise.
