Furosemide is used to reduce extra fluid in the body (edema) caused by conditions such as heart failure, liver disease, and kidney disease. This can lessen symptoms such as shortness of breath and swelling in your arms, legs, and abdomen.This drug is also used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems.Furosemide is a “water pill” (diuretic) that causes you to make more urine. This helps your body get rid of extra water and salt.
How to use furosemide oral
Read the Patient Information Leaflet if available from your pharmacist before you start taking furosemide and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth as directed by your doctor, with or without food, usually once or twice daily. It is best to avoid taking this medication within 4 hours of your bedtime to prevent having to get up to urinate.
Dosage is based on your medical condition, age, and response to treatment. For children, the dose is also based on weight. Older adults usually start with a lower dose to decrease the risk of side effects. Do not increase your dose or take it more often than directed.
