No dose adjustment required for GFR ≥30 m L/min. Not recommended for GFR <30 m L/min.
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.
Child-Pugh A: No adjustment. Child-Pugh B: Not recommended. Child-Pugh C: Contraindicated.
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.
Safety and efficacy not established; no recommended dose.
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.
No dose adjustment required based on age alone; monitor for adverse effects.
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).
None.
None
Ischemic cardiovascular events,Hypertension,Fractures,Seizures,Posterior reversible encephalopathy syndrome (PRES),Hypersensitivity reactions,Fetal toxicity
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.
Pregnancy,Severe hepatic impairment (Child-Pugh C)
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.
Take with food to increase absorption; food with moderate-to-high fat content enhances bioavailability. Avoid grapefruit juice or products containing grapefruit as they may inhibit P-gp and increase darolutamide levels.
No known food interactions. However, methyltestosterone can increase appetite and cause weight gain; a balanced diet is recommended.
NUBEQA (darolutamide) is contraindicated in pregnancy. Based on its mechanism of action (androgen receptor inhibition), it can cause fetal harm. Animal studies have shown adverse developmental effects including embryotoxicity and malformations in rats at exposures below human clinical exposure. No adequate human data exist. It should not be used in pregnant women or those planning to become pregnant. If exposure occurs during pregnancy, the patient should be apprised of the potential hazard to the fetus.
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.
It is unknown whether darolutamide or its metabolites are excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants, breastfeeding should be discontinued during treatment with NUBEQA and for at least 1 week after the final dose. The milk-to-plasma ratio (M/P ratio) is not available.
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.
No dosing adjustment recommendations are available for use during pregnancy because NUBEQA is contraindicated in pregnant women. There are no clinical data regarding the pharmacokinetic changes in pregnancy, and no studies have evaluated the need for dose adjustment in this population. Therefore, no specific dose adjustments for pregnancy are provided.
Contraindicated in pregnancy; no dosing adjustments apply. If inadvertent use occurs, discontinue immediately.
NUBEQA (darolutamide) is a non-steroidal androgen receptor inhibitor with low blood-brain barrier penetration, reducing CNS side effects like falls and fractures. Monitor for cardiovascular events and hypertension; dose adjustment required in severe renal impairment (e GFR 15-29 m L/min) or moderate hepatic impairment (Child-Pugh B). Administer with food to enhance absorption. No dose adjustment for mild renal or hepatic impairment.
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.
Take NUBEQA with food at the same time each day.,Swallow tablets whole; do not crush, chew, or split.,Do not take with strong P-glycoprotein (P-gp) inducers (e.g., rifampin) or inhibitors (e.g., ketoconazole).,Report unusual bleeding, bruising, or signs of bleeding (e.g., blood in urine or stool).,Use effective contraception during treatment and for 1 week after last dose if partner could become pregnant.,Inform your doctor if you have severe kidney or moderate liver problems.
Take exactly as prescribed; do not increase dose or frequency without consulting your doctor.,Report signs of liver problems: yellowing of skin or eyes, dark urine, light-colored stools, abdominal pain.,Notify your doctor if you experience swelling of ankles or feet, trouble breathing, or persistent erections lasting more than 4 hours.,May cause aggressive behavior, mood swings, or depression; contact your doctor if these occur.,Do not take if you are pregnant or breastfeeding.,Keep all appointments for blood tests and liver function monitoring.
