How is Furosemide different from Torasemide?

Both Furosemide and Torasemide are loop diuretics. They are used to treat high blood pressure and edema caused by an underlying liver, kidney or lung diseases. Unlike Torasemide, Furosemide is also used in the treatment of hypercalcemia (high calcium levels in the blood). Torasemide has a longer duration of action and is safer to use in patients with renal failure, as compared to Furosemide.

Should you drink a lot of water when taking Furosemide?

It is advised to take an adequate amount of water if you are taking Furosemide. This is because Furosemide works by eliminating the extra fluid and electrolytes from your body by increasing the urine production. This elimination of fluids may increase the chances of dehydration if you sweat a lot, exercise vigorously or if the climate is hot. However, if you have kidney or heart problems, you must consult your doctor who will suggest the amount of water that you should be taking. Consult your doctor for any further query or concern.

Can Furosemide cause weight gain?

No, Furosemide does not cause weight gain. On the contrary, you may lose weight as it makes your body get rid of the excess of fluids from your body.

Additionally, you may notice increased thirst, causing frequent urination. Immediately contact your doctor if you notice any such side effects or feel unwell.

How long will I need to take it for?
