Furosemide is a loop diuretic (water pill) that prevents your body from absorbing too much salt. This allows the salt to instead be passed in your urine. Furosemide is used to treat fluid retention (edema) in people with congestive heart failure, liver disease, or a kidney disorder such as nephrotic syndrome.
Take furosemide exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Do not take more than your recommended dose. High doses of furosemide may cause irreversible hearing loss.
Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
Furosemide will make you urinate more often and you may get dehydrated easily. Follow your doctor’s instructions about using potassium supplements or getting enough salt and potassium in your diet.
While using this medicine, you may need frequent blood tests.
Keep using this medicine as directed, even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medicine for the rest of your life.
If you need surgery, tell the surgeon ahead of time that you are using this medicine.
Store at room temperature away from moisture, heat, and light. Throw away any furosemide oral solution (liquid) 90 days after opening the bottle, even if it still contains unused medicine.
