Medicine information
Uses & overview
Losartan Potassium is a prescription medication used primarily to manage high blood pressure and certain cardiovascular and kidney-related conditions. It belongs to the angiotensin II receptor blocker (ARB) class of medicines. Losartan works by blocking the effects of angiotensin II, a substance that narrows blood vessels. This allows blood vessels to relax, improves blood flow, and helps lower blood pressure. Healthcare professionals may prescribe Losartan Potassium to adults with hypertension and to selected patients with diabetic kidney disease to help protect kidney function. It may also be used in certain patients with heart-related conditions, depending on their diagnosis and individual treatment requirements. Controlling high blood pressure can help reduce the risk of serious complications, including stroke and other cardiovascular problems. Losartan Potassium is often prescribed alongside lifestyle changes, such as reducing excess dietary salt, maintaining a healthy weight, exercising regularly, and following a balanced diet. Patients with kidney or liver problems, dehydration, or elevated potassium levels should inform their doctor before starting treatment. Losartan may interact with potassium supplements, potassium-containing salt substitutes, certain diuretics, and nonsteroidal anti-inflammatory drugs (NSAIDs).
How to use
Follow the prescribed dosage: Take the strength and dose recommended by your healthcare professional. The appropriate dose depends on your condition, age, kidney function, and response to treatment. Take it regularly: Losartan Potassium is commonly taken once daily, although your doctor may prescribe a different schedule depending on your medical needs. Try to take it at the same time each day. Take with or without food: This medicine can generally be taken with or without food. Follow the instructions provided with your specific product. Swallow the tablet properly: Take the tablet with water. Do not crush or split it unless your pharmacist confirms that this is appropriate for your formulation. Handle missed doses carefully: If you forget a dose, follow the patient leaflet or ask your pharmacist for advice. Do not take a double dose to compensate. Monitor your blood pressure: Check your blood pressure as recommended by your doctor. Report persistent dizziness, faintness, or unusually low readings. Attend follow-up appointments: Your doctor may monitor kidney function and potassium levels, particularly after starting treatment or adjusting your dose. Inform your doctor about other medicines: Mention potassium supplements, salt substitutes containing potassium, diuretics, NSAIDs, and other blood pressure medicines to help prevent interactions.
