It is also available under the brand names Metandren and Oreton Methyl for use specifically by buccal or sublingual administration. Methyltestosterone is available in the form of 2, 5, 10, and 25 mg oral tablets. It was also available in combination with estrogens as esterified estrogens/methyltestosterone (0.625 mg/1.25 mg, 1.25 mg/2.5 mg) and conjugated estrogens/methyltestosterone (0.625 mg/5.0 mg, 1.25 mg/10 mg). Contraindications
Methyltestosterone should be used with caution in women and children, as it can cause irreversible virilization. Due to its estrogenicity, methyltestosterone can also accelerate epiphyseal closure and thereby produce short stature in children and adolescents. It can worsen symptoms in men with benign prostatic hyperplasia. Methyltestosterone should not be used in men with prostate cancer, as androgens can accelerate tumor progression. The drug should be used with caution in patients with pre-existing hepatotoxicity, due to its own potential for hepatotoxicity. Side effects
Adverse effects of methyltestosterone include androgenic side effects like oily skin, acne, seborrhea, increased facial/body hair growth, scalp hair loss, increased aggressiveness and sex drive, and spontaneous erections, as well as estrogenic side effects like breast tenderness, gynecomastia, fluid retention, and edema. In women, methyltestosterone can cause partially irreversible virilization, for instance voice deepening, hirsutism, clitoromegaly, breast atrophy, and muscle hypertrophy, as well as menstrual disturbances and reversible infertility. In men, the drug may also cause hypogonadism, testicular atrophy, and reversible infertility at sufficiently high dosages.Methyltestosterone can sometimes cause hepatotoxicity, for instance elevated liver enzymes, cholestatic jaundice, peliosis hepatis, hepatomas, and hepatocellular carcinoma, with extended use.
