Precautions

US BOXED WARNING: PELIOSIS HEPATITIS/LIVER CELL TUMORS/BLOOD LIPID CHANGES
-Peliosis hepatitis, a condition in which liver and sometimes splenic tissue is replaced with blood-filled cysts, has been reported in patients receiving androgenic anabolic steroid therapy. These cysts are sometimes present with minimal hepatic dysfunction, but at other times they have been associated with liver failure; they are often not recognized until life-threatening liver failure or intra-abdominal hemorrhage develops; drug withdrawal usually results in complete disappearance of lesions.
-Liver cell tumors have also been reported, most often they are benign and androgen-dependent, but fatal malignant tumors have been reported; drug withdrawal often results in regression or cessation of progression of the tumor. However, hepatic tumors associated with androgens or anabolic steroids are much more vascular than other hepatic tumors and may be silent until life-threatening intraabdominal hemorrhage develops.
-Blood lipid changes that are known to be associated with increased risk of atherosclerosis are seen in patients treated with androgens and anabolic steroids; these changes include decreased high density lipoprotein and sometimes increased low density lipoprotein. The changes may be very marked and could have a serious impact on the risk of atherosclerosis and coronary artery disease.

CONTRAINDICATIONS:
-Men with carcinomas of the breast or with known or suspected carcinomas of the prostate
-Women who are or may become pregnant
-Breast Cancer in females with hypercalcemia
-Nephrosis or the nephrotic phase of nephritis
-Hypersensitivity to the drug
-Severe hepatic dysfunction

Monitoring:
-Periodic liver function tests should be performed
-Prepubertal males should have X-ray examinations of bone age every 6 months
-Periodic evaluation of hemoglobin and hematocrit checking for polycythemia should be performed, especially with high doses
-Periodic evaluation of serum iron and iron binding capacity
-Periodic evaluation of serum lipids
-Women should have frequent determinations of urine and serum calcium levels

Patient advice:
-Female patients should be instructed to report signs of virilization such as deepening voice, hirsutism, acne, clitoromegaly, and/or menstrual irregularities.
-Male patients should be instructed to report too frequent or persistent penile erections or aggravation of acne.
