Peliosis hepatis, a condition in which liver and, sometimes, splenic tissue is replaced with blood-filled cysts, has occurred in patients receiving androgenic anabolic steroids. These cysts are sometimes present with minimal hepatic dysfunction and have been associated with liver failure. Often, they are not recognized until life-threatening liver failure or intra-abdominal hemorrhage develops.

Withdrawal of drug usually results in complete disappearance of lesions. Most often these tumors are benign and androgen-dependent, but fatal malignant tumors have occurred.

Withdrawal of drug often results in regression or cessation of tumor progression. However, hepatic tumors associated with androgens or anabolic steroids are much more vascular than other hepatic tumors and may be silent until life-threatening, intra-abdominal hemorrhage develops. Blood lipid changes associated with increased risk of atherosclerosis are seen in patients treated with androgens and anabolic steroids. The changes may be very marked and could have a serious impact on the risk of atherosclerosis and coronary artery disease.

May cause blood lipid changes with increased risk of arteriosclerosis. Anabolic steroids may cause peliosis hepatis or liver cell tumors which may not be apparent until liver failure or intra-abdominal hemorrhage develops. Discontinue in case of cholestatic hepatitis with jaundice or abnormal liver function tests.

Use with caution in patients with hepatic impairment. Use with caution in patients with breast cancer; may cause hypercalcemia by stimulating osteolysis. Discontinue use if hypercalcemia occurs. May have adverse effects on glucose tolerance; use caution in patients with diabetes.

Use with caution in patients with conditions influenced by edema eg, cardiovascular disease, migraine, seizure disorder, renal impairment ; may cause fluid retention. Use caution with concomitant warfarin therapy; warfarin dose may need to be significantly decreased.

May accelerate bone maturation without producing compensatory gain in linear growth in children; effect may continue for 6 months after the drug is stopped; in prepubertal children perform radiographic examination of the left hand and wrist every 6 months to determine the rate of bone maturation and to assess the effect of treatment on the epiphyseal centers.

May cause mild virilization in females; monitor for signs of virilization deepening of the voice, hirsutism, acne, clitoromegaly. Discontinue with evidence of mild virilization in female patients; early discontinuation may prevent irreversible virilization. Signs of virilization deepening voice, hirsutism, acne, clitoromegaly ; urine and serum calcium in women with breast cancer.
