Mechanism of Action
Pharmacology
Suppresses gonadotropic functions of the pituitary and may exert a direct effect upon the testes.
Indications and Usage
Management of anemia of renal insufficiency and has been shown to increase Hgb and RBC mass.
Contraindications
Men with carcinoma of the breast or known or suspected carcinoma of the prostate; carcinoma of the breast in women with hypercalcemia; pregnancy; nephrosis or nephrotic phase of nephritis.
Dosage and Administration
Adults
IM 50 to 100 mg/wk for women and 100 to 200 mg/wk for men. If no hematologic improvement is seen within the first 6 mo, discontinue therapy.
Children 2 to 13 yr of age
IM 25 to 50 mg q 3 to 4 wk.
General Advice
· For deep IM administration only, preferably into gluteal muscle. Not for intradermal, subcutaneous, IV, or intra-arterial administration.
· Rotate injection sites.
· Do not administer if particulate matter, cloudiness, or discoloration noted.
Storage/Stability
Store vials at controlled room temperature (59° to 86°F). Protect from light. Store in carton until contents are used.
Drug Interactions
Anticoagulants (eg, warfarin)
Anticoagulant effects may be increased.
Insulin, oral hypoglycemic agents
May decrease glucose control; dosage adjustments may be necessary.
Laboratory Test Interactions
Thyroxine-binding globulin may be decreased, resulting in decreased total T 4 serum levels and increased resin uptake of T 3 and T 4 . Free thyroid hormone levels are not changed.
Adverse Reactions
CNS
Depression; excitation; habituation; insomnia; increased and decreased libido.
Dermatologic
Acne (women and prepubertal boys); hirsutism and male pattern baldness (women).
EENT
Deepening of voice (women).
GI
Diarrhea; nausea; vomiting.
Genitourinary
Gynecomastia; inhibition of testicular atrophy and oligospermia, testicular function, impotence, chronic priapism, epididymitis, bladder irritability (postpubertal men); increased frequency of erection, phallic enlargement (prepubertal men); clitoral enlargement, menstrual irregularities (women).
Hepatic
Hepatocellular neoplasms; peliosis hepatitis.
Metabolic-Nutritional
Decreased glucose tolerance and HDL; increased creatine, creatinine excretion, serum creatinine phosphokinase, and serum levels of LDL; serum electrolyte retention (including calcium, chloride, phosphate, potassium, sodium).
Musculoskeletal
Premature closure of epiphyses (children).
Miscellaneous
Edema.
Precautions
Warnings
Peliosis hepatitis, a condition in which liver and sometimes splenic tissue is replaced with blood-filled cysts, occurred in patients receiving androgenic anabolic steroids. The condition may not be recognized until life-threatening liver failure or intra-abdominal hemorrhage develops. Lesions completely resolve upon discontinuation. Liver cell tumors, often benign and androgen-dependent but sometimes malignant, have occurred. Drug discontinuation often results in regression or cessation of tumor growth. Hepatic tumors associated with androgens or anabolic steroids may be silent until life-threatening, intra-abdominal hemorrhage develops. Blood lipid changes, including decreased HDL and increased LDL, associated with increased risk of atherosclerosis are seen in some patients treated with androgens and anabolic steroids.
Monitor
Assess Hgb and Hct, liver function
