Bumetanide (patient information)

# IMPORTANT WARNING
Bumetanide is a strong diuretic ('water pill'). It is important that you take it exactly as prescribed by your doctor.

# Why this medication is prescribed
Bumetanide, a 'water pill,' is used to reduce the swelling and fluid retention caused by various medical problems, including heart or liver disease. It also is used to treat high blood pressure. It causes the kidneys to get rid of unneeded water and salt from the body into the urine.
This medicine is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

# How this medication should be used
Bumetanide comes as a tablet to take by mouth. It usually is taken once a day, in the morning. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take bumetanide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Bumetanide controls high blood pressure but does not cure it. Continue to take bumetanide even if you feel well. Do not stop taking bumetanide without talking to your doctor.

# Special precautions
Before taking bumetanide:
- tell your doctor and pharmacist if you are allergic to bumetanide, sulfa drugs, or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially other medications for high blood pressure, corticosteroids (e.g., prednisone), digoxin (Lanoxin), indomethacin (Indocin), lithium (Eskalith, Lithobid), probenecid (Benemid), and vitamins.
- tell your doctor if you have or have ever had diabetes, gout, or kidney or liver problems.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. Do not breast-feed while taking this medicine. If you become pregnant while taking bumetanide, call your doctor.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking bumetanide.
