Bumetanide is a strong diuretic ('water pill') and may cause dehydration and electrolyte imbalance. It is important that you take it exactly as told by your doctor. If you experience any of the following symptoms, call your doctor immediately: rapid, excessive weight loss; decreased urination; dry mouth; thirst; nausea; vomiting; weakness; drowsiness; confusion; muscle pain or cramps; or rapid or pounding heartbeats.
Why is this medication prescribed?
Bumetanide is used to treat edema (fluid retention; excess fluid held in body tissues) caused by various medical problems, including heart, kidney, and liver disease. Bumetanide is in a class of medications called diuretics ('water pills'). It works by causing the kidneys to get rid of unneeded water and salt from the body into the urine.
How should this medicine be used?
Bumetanide comes as a tablet to take by mouth. It usually is taken once a day. When used to treat edema, a second or third dose may be given every 4 to 5 hours depending on the amount of swelling. 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 edema but does not cure it. Continue to take bumetanide even if you feel well. Do not stop taking bumetanide without talking to your doctor.
