GENERIC NAME: bumetanide
DISCONTINUED BRAND: Bumex (discontinued brand)
DRUG CLASS AND MECHANISM: Bumetanide is a potent diuretic (water pill) that causes a profound increase in urine output (diuresis) by preventing the kidney from retaining fluid. Specifically, it blocks the reabsorption of sodium and fluid from the kidney's tubules. It is in a class of diuretics called "loop" diuretics which also includes furosemide (Lasix) and torsemide (Demadex). One mg of bumetanide is approximately equivalent to 10-20 mg of torsemide and 40 mg of furosemide. The potent diuretic effect of bumetanide can cause the loss of large amounts of body water leading to dehydration as well as the loss of electrolytes (for example, sodium, potassium, magnesium, and calcium). Therefore, careful medical supervision is necessary during treatment. Bumetanide was approved for use by the FDA in 1983.
PRESCRIBED FOR: Bumetanide is used in the management of edema (excessive fluid accumulation) associated with congestive heart failure, kidney and liver disease. It also is used (off-label) in the treatment of mild to moderate hypertension (high blood pressure).
SIDE EFFECTS: Potent diuretics like bumetanide can cause low blood levels of potassium, magnesium, sodium and calcium. Additionally, fluid losses can occur leading to dehydration.
The symptoms of dehydration may include:
- dry mouth,
- reduced kidney function,
- heart arrhythmias,
- muscle aches and pains,
- nausea, and
