Furo is a type of medicine that helps the body get rid of extra fluid. The body needs fluid to work properly, but sometimes it can have too much fluid, which can make you swell up or cause problems with your breathing or heart. Furo helps kick out some of that extra fluid by making you pee more than usual. It's like a magical potion that helps your body get rid of what it doesn't need. But just like any potion, you should only take it when your doctor tells you to and follow their instructions carefully.
