Lasix Uses, Dosage, Side Effects & Price in Pakistan

1. Quick Info (Mukhtasir Maloomat)

2. What is Lasix? (Lasix kya hai)

Lasix belongs to a group of medicines called loop diuretics, commonly known as water pills. Its active ingredient, furosemide, works on the kidneys by blocking the reabsorption of sodium and chloride in a specific part of the kidney tubule called the loop of Henle. This causes the kidneys to remove more salt and water from the body through urine, which reduces excess fluid buildup in the body. Lasix is typically prescribed for adults with conditions where the body retains too much fluid, such as swelling in the legs or abdomen, or fluid buildup related to the heart, liver, or kidneys. It requires a doctor's prescription and ongoing monitoring since it changes how the body handles fluids and salts.

Within the loop diuretic class, Lasix is one of the most established and widely used options in Pakistan, valued for its fast onset of action. Other loop diuretics work in a broadly similar way but may differ in strength or duration of effect. Always take Lasix as directed by your doctor or pharmacist.
