Losartan is an angiotensin II receptor blocker (ARB) used primarily to treat high blood pressure (hypertension) and heart failure. It works by relaxing blood vessels, which lowers blood pressure and improves blood flow. It’s also sometimes prescribed for kidney protection in patients with type 2 diabetes and proteinuria.

Key Points:

• Brand Names: Cozaar, among others.
• Dosage: Typically 25–100 mg daily, taken orally, as prescribed by a doctor.
• Common Side Effects: Dizziness, fatigue, headache, high potassium levels (hyperkalemia).
• Serious Side Effects: Kidney problems, low blood pressure, allergic reactions (rare).
• Precautions:
  • Avoid during pregnancy (can harm the fetus).
  • Use cautiously if you have kidney or liver issues.
  • Monitor potassium levels and avoid potassium supplements unless advised.
• Interactions: Can interact with NSAIDs (e.g., ibuprofen), diuretics, or lithium.

Always take losartan as prescribed and consult your doctor for personalized advice, especially if you’re on other medications or have underlying conditions.
