Bumetanide, sold under the brand name Bumex among others, is a medication used to treat swelling and high blood pressure.[2] This includes swelling as a result of heart failure, liver failure, or kidney problems.[2] It may work for swelling when other medications have not.[2] For high blood pressure it is not a preferred treatment.[2] It is taken by mouth, or by injection into a vein or muscle.[2] Effects generally begin within an hour and last for about six hours.[2]

Common side effects include dizziness, low blood pressure, low blood potassium, muscle cramps, and kidney problems.[2] Other serious side effects may include hearing loss and low blood platelets.[2] Blood tests are recommended regularly for those on treatment.[2] Safety during pregnancy and breastfeeding is unclear.[3] Bumetanide is a loop diuretic and works by decreasing the reabsorption of sodium by the kidneys.[4][2]

Bumetanide was patented in 1968 and came into medical use in 1972.[5] It is on the World Health Organization's List of Essential Medicines.[6] It is available as a generic medication.[4] In 2020, it was the 270th most commonly prescribed medication in the United States, with more than 1 million prescriptions.[7][8]
