No specific dose adjustment required for renal impairment; monitor serum testosterone levels and clinical response. For severe renal impairment (GFR <30 m L/min), consider increased monitoring due to potential fluid retention.
GFR 10-50 m L/min: reduce dose by 50%. GFR <10 m L/min: avoid use.
Contraindicated in patients with severe hepatic dysfunction (Child-Pugh class C). For mild to moderate impairment (Child-Pugh class A or B), use with caution and consider dose reduction; monitor liver function tests regularly.
Child-Pugh A: reduce dose by 50%. Child-Pugh B: avoid use. Child-Pugh C: contraindicated.
Not recommended for use in children; safety and efficacy not established. For delayed puberty in adolescent males: testosterone enanthate 50-200 mg intramuscularly every 2-4 weeks, titrated to response, with monitoring of bone age.
Not recommended for use in children due to risk of premature epiphyseal closure and virilization.
Start at low end of dosing range (e.g., testosterone cypionate 50 mg intramuscularly every 4 weeks or gel 25 mg daily) due to potential increased sensitivity and risk of prostatic hypertrophy or cardiovascular events. Monitor serum testosterone, hematocrit, and prostate-specific antigen (PSA).
Use with caution; consider lower starting dose due to increased risk of fluid retention, hypertension, and prostatic hypertrophy in males.
None
Risk of bradyarrhythmia and atrioventricular block, requiring first-dose monitoring for 6 hours. Fatal infections, including opportunistic infections, have occurred. Macular edema has been reported.
Risk of hepatotoxicity; use with caution in patients with liver disease. Monitor liver function, lipid profile, and prostate-specific antigen (PSA). May cause fluid retention, gynecomastia, priapism, and sleep apnea. Not for use in women who are pregnant or breastfeeding. May accelerate growth of prostate cancer and benign prostatic hyperplasia. Androgenic effects may cause virilization in women.
May cause bradycardia and AV block; monitor heart rate after first dose. Increased risk of infections, including herpes viruses and cryptococcal meningitis. Macular edema, especially in patients with diabetes or uveitis. Posterior reversible encephalopathy syndrome (PRES). Respiratory effects, including decreased FEV1 and DLCO. Hepatic injury; monitor liver enzymes.
Men with carcinoma of the prostate or breast; history of hypersensitivity to testosterone or any component; women who are pregnant or may become pregnant (risk of fetal harm); patients with severe hepatic or cardiac disease.
Recent myocardial infarction, unstable angina, stroke, transient ischemic attack, decompensated heart failure, history of Mobitz type II 2nd or 3rd degree AV block, sick sinus syndrome unless pacemaker is present, or severe untreated sleep apnea.
No known food interactions. However, methyltestosterone can increase appetite and cause weight gain; a balanced diet is recommended.
No significant food interactions reported. Avoid excessive alcohol consumption due to hepatotoxic effects.
Android 10 is a combination of methyltestosterone and ethinyl estradiol. Methyltestosterone is an androgen; exposure during pregnancy, particularly during the first trimester, can cause virilization of the female fetus. Ethinyl estradiol is contraindicated in pregnancy due to risk of fetal harm. Use is contraindicated in all trimesters.
ANDROID-F contains methyltestosterone, a synthetic androgen. Androgens are teratogenic in humans. In first trimester: masculinization of female fetus, including clitoromegaly, labial fusion, and urogenital sinus abnormalities. Second and third trimesters: continued virilization of female fetus; no increased risk of malformations in male fetuses. Contraindicated in pregnancy.
Methyltestosterone and ethinyl estradiol are excreted in breast milk. Methyltestosterone may cause virilization in female infants. Ethinyl estradiol may reduce milk production and quality. M/P ratio not available. Breastfeeding is contraindicated.
Methyltestosterone is excreted in breast milk. No specific M/P ratio available. May cause virilization in female infants and precocious development in male infants. Breastfeeding is contraindicated during therapy.
Contraindicated in pregnancy; no dosing adjustments apply. If inadvertent use occurs, discontinue immediately.
ANDROID-F is contraindicated in pregnancy; no dosing recommendations for use in pregnancy. No established dose adjustments exist as the drug should not be administered.
Android 10 is a brand name for methyltestosterone, an androgen and anabolic steroid. Use is restricted to replacement therapy in males with hypogonadism or delayed puberty due to androgen deficiency. Monitor liver function due to risk of peliosis hepatis and hepatocellular carcinoma. Contraindicated in males with breast or prostate cancer. Can cause erythrocytosis; monitor hematocrit. Discontinue if signs of virilization in women or priapism in men. Use caution in elderly due to increased risk of prostatic hypertrophy.
Android-F is a brand of methyltestosterone, an androgen used primarily for male hypogonadism. Monitor liver function due to potential hepatotoxicity. Avoid in males with breast or prostate cancer. Use with caution in older patients due to increased risk of prostatic hypertrophy. May suppress clotting factors II, V, VII, and X.
