Furosemide can be used to reduce excessive blood calcium levels which are inherently dangerous to the kidneys. Calcium is one of the minerals furosemide encourages the body to lose. Often prednisone is used with furosemide for this use as it too encourages calcium excretion.
Furosemide can also be helpful in reducing dangerously high potassium blood levels and has been used in the horse to treat excerise induced pulmonary hemorrhage (nose bleeds).
