Spironolactone is a diuretic that removes excess fluid from the body by increasing the flow of urine. It is used to treat congestive heart failure and ascites (fluid in the abdomen).
Side effects may include excessive thirst, drowsiness, weakness, restlessness, diminished urination in relation to fluid intake, or stomach upset. Notify your veterinarian if side effects are noted and they are troublesome.Other side effects may occur. If you notice anything unusual, contact your veterinarian.
Spironolactone works by preventing the body from absorbing too much salt and keeps potassium levels from getting too low. Spironolactone may be used for several cardiovascular and renal conditions. Spironolactone also treats fluid retention (edema) in people with congestive heart failure, cirrhosis of the liver, or a kidney disorder called nephrotic syndrome. This medication is also used to treat or prevent hyperkalemia (low potassium levels in the blood).
Spironolactone should be given orally as directed by your veterinarian.
