Furosemide is a prescription drug. It’s available in two forms that you take by mouth: a tablet and a solution. It’s also available as an injectable solution, which is given by a healthcare provider.
The furosemide tablet is available as the brand-name drug Lasix. It’s also available as a generic drug. Generic drugs usually cost less. In some cases, they may not be available in every strength or form as the brand-name version.
