Furosemide oral is taken by mouth. The injection is injected into a muscle or given as an infusion into a vein. A healthcare provider will give you this injection if you are unable to take the medicine by mouth.
You may receive your first dose in a hospital or clinic setting if you have severe liver disease.
Do not take more than your recommended dose. High doses of furosemide may cause irreversible hearing loss.
Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
Furosemide doses are based on weight in children. Your child's dose needs may change if the child gains or loses weight.
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.
Your blood pressure will need to be checked often and you may need other medical tests.
If you have high blood pressure, keep using this medicine 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 unused oral liquid after 90 days.
