Furosemide is a prescription medication used to treat edema (tissue swelling) associated with congestive heart failure, cirrhosis of the liver, and kidney disease. It also treats high blood pressure. Furosemide belongs to a group of drugs called diuretics, also known as “water pills.” These work by causing the kidneys to get rid of unneeded water and salt from the body into the urine.

This medication comes in tablet and oral (by mouth) solution forms and is taken once or twice a day, with or without food.

This medication is available in an injectable form to be given directly into a vein (IV) or the muscle (IM) by a healthcare professional.

Common side effects of furosemide include diarrhea, constipation, cramping, and ringing in the ears. Furosemide can also cause dizziness. Do not drive or operate heavy machinery until you know how furosemide affects you.
