Frequently asked questions

How is Flasix Injection 2ML different from Torasemide?

Both Flasix Injection 2ML 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, Flasix Injection 2ML 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 Flasix Injection 2ML.

Should you drink a lot of water when taking Flasix Injection 2ML?

It is advised to take an adequate amount of water if you are taking Flasix Injection 2ML. This is because Flasix Injection 2ML 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.
