Overview
SM Fusix 40mg Tablet contains furosemide 40mg, a potent loop diuretic used to treat fluid retention (oedema) caused by heart failure, liver disease, or kidney disease, and to help control high blood pressure.
Furosemide works by blocking sodium and chloride reabsorption in a specific part of the kidney called the loop of Henle, which increases the excretion of sodium, chloride, and water into the urine, reducing fluid overload and lowering blood pressure.
How it Works
Furosemide inhibits the sodium-potassium-chloride co-transporter in the thick ascending loop of Henle in the kidney, preventing the reabsorption of sodium and chloride back into the blood. This causes more sodium, chloride, and water to be excreted in the urine, reducing the volume of fluid in the body and lowering blood pressure.
Directions for Use
Take in the morning, or as directed by your doctor, to avoid needing to urinate frequently during the night. If a second dose is prescribed, take it in the early afternoon. Take with or without food.
Dosage
The dose of furosemide is individualised by your doctor based on the condition being treated and your response, commonly starting at 20mg to 80mg once daily and adjusted as needed. Take exactly as prescribed; do not adjust the dose yourself.
Shelf Life
Use this product before the expiry date stated on the packaging. Do not use the medicine if the expiry date has passed.
