Mitotane

Why has my veterinarian prescribed this medicine?

Mitotane is primarily used to treat Cushing's disease in dogs.  It has also been used to treat adrenal tumors. Mitotane reduces the amount of cortisone-like hormones produced by the adrenal cortex. These steroids are important for various body functions; however excessive levels of these hormones can cause problems.
