Hepatic: Cholestatic jaundice with, rarely, hepatic necrosis and death. Hepatocellular neoplasms and peliosis hepatis have been reported in association with long-term androgenic anabolic steroid therapy (see WARNINGS).
Prepubertal: Phallic enlargement and increased frequency of erections.
In Both Sexes
Increased or decreased libido.
CNS: Excitation, insomnia.
Leukemia has been observed in patients with aplastic anemia treated with oxymetholone. The role, if any, of oxymetholone is unclear because malignant transformation has been seen in patients with blood dyscrasias and leukemia has been reported in patients with aplastic anemia who have not been treated with oxymetholone.
Larynx: Deepening of the voice in women.
Skin: Acne (especially in women and prepubertal boys).
Body as a Whole: Chills.
Metabolic/Endocrine: Decreased glucose tolerance (see PRECAUTIONS), increased serum levels of low-density lipoproteins and decreased levels of high-density lipoproteins (see PRECAUTIONS, Laboratory Tests), increased creatine and creatinine excretion, increased serum levels of creatinine phosphokinase (CPK). Reversible changes in liver function tests also occur, including increased Bromsulphalein (BSP) retention and increases in serum bilirubin, glutamic-oxaloacetic transaminase (SGOT), and alkaline phosphatase.
Drug Abuse And Dependence
ANADROL Tablets is considered to be a controlled substance and is listed in Schedule III.

Warfarin: Clinically significant pharmacokinetic and pharmacodynamic interactions between anabolic steroids and warfarin have been reported in healthy volunteers. When anabolic steroid therapy is initiated in a patient already receiving treatment with warfarin, the INR (international normalized ratio) or prothrombin time (PT) should be monitored closely and the dose of warfarin adjusted as necessary until a stable target INR or PT has been achieved. Furthermore, in patients receiving both ANADROL Tablets and warfarin, careful monitoring of the INR or PT and adjustment of the warfarin dosage, if indicated, are recommended when the ANADROL dose is changed or discontinued. Patients should be closely monitored for signs and symptoms of occult bleeding.
Anticoagulants: Anabolic steroids may increase sensitivity to oral anticoagulants. Dosage of the anticoagulant may have to be decreased in order to maintain the desired prothrombin time. Patients receiving oral anticoagulant therapy require close monitoring, especially when anabolic steroids are started or stopped.
Drug/Laboratory Test Interferences
Therapy with androgenic anabolic steroids may decrease levels of thyroxine-binding globulin resulting in decreased total T4 serum levels and increased resin uptake of T3 and T4. Free thyroid hormone levels remain unchanged and there is no clinical evidence of thyroid dysfunction. Altered tests usually persist for 2 to 3 weeks after stopping anabolic therapy.
Anabolic steroids may cause an increase in prothrombin time.
Anabolic steroids have been shown to alter fasting blood sugar and glucose tolerance tests.
