Side Effects

Adrenal Crisis in the Setting of Shock or Severe Trauma

In patients taking MITODX, adrenal crisis occurs in the setting of shock or severe trauma and

response to shock is impaired. Administer hydrocortisone, monitor for escalating signs of shock,

and discontinue MITODX until recovery.

CNS Toxicity

CNS toxicity, including sedation, lethargy, and vertigo, occurs with MITODX treatment. Mitotane plasma concentrations exceeding 20 mcg/mL are associated with a greater incidence of toxicity.

Adrenal Insufficiency

Treatment with MITODX can cause adrenal insufficiency. Institute steroid replacement as clinically indicated. Measure free cortisol and corticotropin (ACTH) levels to achieve optimal steroid replacement.

Embryo-Fetal Toxicity

MITODX can cause fetal harm when administered to a pregnant woman.Abnormal pregnancy outcomes, such as preterm births and early pregnancy loss, can occur in patients exposed to mitotane during pregnancy. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with MITODX and after discontinuation of treatment for as long as mitotane plasma levels are detectable

Ovarian Macrocysts in Premenopausal Women

Ovarian macrocysts, often bilateral and multiple, have been reported in premenopausal patients receiving MITODX. Complications from these cysts, including adnexal torsion and hemorrhagic cyst rupture, have been reported. In some cases, improvement after mitotane discontinuation has been described. Advise female patients to seek medical care if they experience gynecological symptoms such as vaginal bleeding and/or pelvic pain.

· Adrenal Crisis in the Setting of Shock or Severe Trauma 

· CNS Toxicity

·Adrenal Insufficiency

· Ovarian macrocysts

The following adverse reactions associated with the use of MITODX were identified in clinical trials or postmarketing reports. Because these reactions were reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency reliably or to establish a causal relationship to drug exposure.

· Maculopathy

· Hepatitis, elevation of liver enzymes

· Gynecomastia

· Hypercholesterolemia, hypertriglyceridemia

· Decreased blood androstenedione and decreased blood testosterone in females, increased sex hormone binding globulin in females and males, decreased blood free testosterone in males.

Less common adverse reactions include: visual blurring, diplopia, lens opacity, retinopathy, prolonged bleeding time, hematuria, hemorrhagic cystitis, albuminuria, hypertension, orthostatic hypotension, flushing, generalized aching, and fever.
