            Contraindicated (13)

            • cariprazine

              mitotane will decrease the level or effect of cariprazine by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Contraindicated. CYP3A4 is responsible for the formation and elimination of cariprazine's active metabolites. The effect of CYP3A4 inducers on cariprazine exposure has not been evaluated and the net effect is unclear.

            • cobimetinib

              mitotane will decrease the level or effect of cobimetinib by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Contraindicated. Avoid coadministration. Strong or moderate CYP3A inducers may decrease cobimetinib systemic exposure by >80% and reduce its efficacy.

            • doravirine

              mitotane will decrease the level or effect of doravirine by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Contraindicated. Coadministration of doravirine with a strong CYP3A inducer may decrease doravirine plasma concentrations and/or effects.

            Black Box Warnings

            Administered under the supervision of an experienced cancer chemotherapy physician in a facility equipped to manage complications

            The drug suppresses adrenal function; stop therapy temporarily after shock or severe trauma and administer exogenous steroids since the drug depressed adrenal function may not immediately return

            Contraindications

            Hypersensitivity

            Cautions

            Discontinue immediately following shock or severe trauma; exogenous steroid should be administered in such circumstances

            Adrenal insufficiency may develop requiring adrenal steroid replacement

            Patients with liver disease in addition to metastatic lesion of adrenal cortex

            Long-term administration of high doses may lead to brain damage

            Mitotane plasma concentrations >20 mcg/mL associated with a greater incidence of high grade CNS toxicity

            Increases hormone binding proteins, measurement of free cortisol and corticotropin (ACTH) levels may be useful in achieving optimal steroid replacement

            Prolonged bleeding time reported; consider this possibility prior to any surgical intervention or if coadministered with anticoagulants

            Reduces tumor mass but no evidence of cure

            Advise women of reproductive potential of risks to fetus; use effective contraception

            Ovarian macrocysts, often bilateral and multiple, reported in premenopausal patients; complications from cysts, including adnexal torsion and hemorrhagic cyst rupture, reported; in some cases, improvement after mitotane discontinuation reported; advise female patients to seek medical care if they experience gynecological symptoms such as vaginal bleeding and/or pelvic pain

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

            Drug interaction overview

            • Mitotane is a strong CYP3A inducer; concomitant use of mitotane may decrease concentrations of CYP3A substrates, which may reduce efficacy of these substrates
            • Avoid concomitant use of mitotane with certain CYP3A4 substrates where minimal concentration changes may lead to therapeutic failure; if concomitant use cannot be avoided, increase CYP3A substrate dosage in accordance with approved product labeling

            Pregnancy & Lactation

            Pregnancy Category: D

            Lactation: Detected in breast milk; because of the potential for serious adverse reactions in nursing infants from mitotane, advise women to discontinue nursing during therapy and after treatment discontinuation for as long as mitotane plasma levels are detectable

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.
