Furosemide Tablet Uses, Dosage, Side Effects & Price in Pakistan

1. Quick Info (Mukhtasir Maloomat)

2. What is Furosemide Tablet? (Furosemide Tablet kya hai)

Lasix Tablet is a powerful diuretic used in Pakistan for oedema (swelling) caused by heart failure, liver disease, and kidney disease. It belongs to the Loop Diuretic class. Furosemide blocks the sodium/potassium/2Cl- cotransporter in the thick ascending portion of the loop of Henle in the kidney — this prevents the kidney from reabsorbing salt and water, resulting in powerful diuresis. Effect begins 30-60 minutes after the oral tablet.

3. Uses (Fayde / Kis kaam aati hai)

• Fluid retention related to heart failure, liver disease or kidney disease when prescribed
• High blood pressure when a clinician selects a loop diuretic

4. Who May Use It (Kis ko leni chahiye)

A healthcare professional should confirm that the indication, age and exact formulation match the patient’s needs. An ingredient match alone does not make another brand or formulation interchangeable.

5. When Not to Use (Kab nahi leni chahiye)

• Don't use Lasix if you are allergic to furosemide or sulfonamides
• Potassium monitoring essential — severe hypokalemia can cause cardiac arrhythmia (especially dangerous with digoxin)
• Risk of dehydration and orthostatic hypotension — rise slowly from sitting/lying position
• Ototoxicity risk (hearing loss) with high IV doses or rapid infusion — rare with oral use
• Take in morning to avoid nocturnal (night-time) diuresis disrupting sleep
• Furosemide can raise blood glucose — use with caution in diabetes

6. Dosage (Kitni leni hai)

Adult guidance

The prescriber adjusts the dose to fluid retention, blood pressure, kidney function and electrolytes. It is usually taken in the morning; a second prescribed dose is generally taken earlier in the day rather than at bedtime.
