Furosemide solution is a strong fluid-reducing medicine (diuretic). Using too much of furosemide solution can cause you to lose too much water and electrolytes. This can lead to serious health problems. Your doctor will follow you closely while you use furosemide solution to change the dose to match your body's needs.
Furosemide solution is used for:
Treating fluid buildup and swelling caused by certain conditions (eg, congestive heart failure, liver cirrhosis, kidney problems). It is also used alone or with other medicines to treat high blood pressure. It may also be used for other conditions as determined by your doctor.
Furosemide solution is a loop diuretic. It works by helping the kidneys to remove fluid from the body.
Do NOT use furosemide solution if:
- you are allergic to any ingredient in furosemide solution
- you are unable to urinate
- you are taking chloral hydrate, ethacrynic acid, disulfiram, or metronidazole
Contact your doctor or health care provider right away if any of these apply to you.
