Losar H Tablet is a combination medicine containing Losartan and Hydrochlorothiazide, used to effectively control high blood pressure (hypertension). By working in different ways, Losar H Tablet helps manage blood pressure, which is crucial for preventing serious complications like heart attacks, strokes, and kidney failure if left untreated. You can take Losar H Tablet with or without food. Your doctor will determine the appropriate dose based on your condition and how you respond to the medicine. It's important to take it at the same time each day for best results. Continue taking this medicine as prescribed by your doctor, even if you feel well. As Losar H Tablet contains Hydrochlorothiazide, a diuretic (water pill), it will increase urination, so it's generally best to avoid taking it within four hours of going to bed. Regular and consistent use of Losar H Tablet is key to managing your blood pressure and minimizing the risk of heart attack or stroke. Dizziness is a common side effect of Losar H Tablet. Other possible side effects include feeling tired, nausea, diarrhea, headache, and a decrease in blood pressure. Increased urination is an intended effect of Hydrochlorothiazide and helps in controlling your blood pressure, not a side effect to worry about. Most side effects are rare. Always read the patient leaflet provided with your medicine. Inform your doctor if any side effects bother you or do not go away. Your doctor may be able to adjust your dose or suggest an alternative medicine. Losar H Tablet is not recommended during pregnancy due to potential risks to the baby. Consult your doctor immediately if you are pregnant or plan to become pregnant while taking this medicine. If you have kidney or liver disease, heart conditions, or diabetes, discuss these with your doctor before starting Losar H Tablet. Consuming alcohol while on this medication can further lower your blood pressure and may increase the risk of side effects.'
