Overview

SM Fusix 40mg Tablet is a prescription-only medicine (POM) presented as a tablet, with Furosemide 40mg as its active ingredient content.

This page is limited to product, safety and handling information, in line with Malaysian rules on prescription medicine information for the public. Your prescriber or pharmacist is the right source for anything beyond that, together with the leaflet inside the pack.

Through DoctorOnCall, this product is supplied after an online consultation with a licensed doctor and a valid prescription, and it is checked by a registered pharmacist before dispensing. Take it exactly as prescribed, and speak to your doctor before stopping, changing the dose, or starting any other medicine alongside it.

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.

Storage Instructions

Store below 30°C in a dry place, away from direct sunlight and out of reach of children.

Side Effects

Contraindications

  • Known hypersensitivity to furosemide or sulfonamide-derived medicines
  • Anuria (inability to produce urine) or severe kidney failure not responding to furosemide
  • Severe electrolyte depletion or dehydration
  • Hepatic coma or pre-coma associated with severe liver disease

Drug / Food Interactions

  • Lithium – furosemide can reduce lithium clearance and increase the risk of lithium toxicity
  • NSAIDs – may reduce the diuretic and blood-pressure-lowering effect of furosemide
  • Digoxin – low potassium caused by furosemide can increase the risk of digoxin toxicity
  • ACE inhibitors or ARBs – combined use can cause a significant drop in blood pressure, especially with the first dose

Quick Tips

  • Take your dose in the morning to avoid nighttime trips to the bathroom
  • Weigh yourself regularly and report sudden weight gain or worsening swelling to your doctor
  • Rise slowly from sitting or lying down to reduce dizziness
