Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Androgen receptor agonist; testosterone replacement therapy to restore serum testosterone to physiologic levels.
Androgen receptor agonist; stimulates protein synthesis and growth of androgen-sensitive tissues.
Primary hypogonadism (congenital or acquired),Hypogonadotropic hypogonadism,Off-label: delayed puberty in males, certain breast cancers
Testosterone replacement therapy for male hypogonadism,Off-label: delayed puberty in males
50 mg (5 g gel) applied topically once daily, preferably in the morning. Dose may be adjusted between 25 mg (2.5 g gel) and 100 mg (10 g gel) based on serum testosterone levels.
2.5-10 mg orally once daily in the morning for androgen replacement therapy in adult males.
The terminal elimination half-life of testosterone from Andro Gel is approximately 10-12 hours when applied topically, but due to continuous absorption from the skin depot, serum levels are sustained over 24 hours, allowing once-daily dosing.
Terminal elimination half-life is 3.5–5.5 hours; clinical effects may persist for several days due to active metabolites.
Hepatic via CYP3A4, CYP2C9, and 17β-hydroxysteroid dehydrogenase; metabolites include estradiol and dihydrotestosterone.
Hepatic via CYP3A4 and CYP2B6; undergoes first-pass metabolism.
Approximately 90% of a topical dose is excreted in urine as conjugated and unconjugated metabolites, with about 6% excreted in feces via bile; renal elimination is the primary route.
Primarily renal: ~90% as glucuronide and sulfate conjugates, 6% as unchanged drug; ~5% fecal via bile.
Approximately 98% of circulating testosterone is protein-bound: 40-50% bound to sex hormone-binding globulin (SHBG) and 50-60% loosely bound to albumin.
98% bound to sex hormone-binding globulin (SHBG) and albumin.
The apparent volume of distribution of testosterone is about 1.0 L/kg, reflecting extensive distribution into tissues, particularly muscle, skin, and male reproductive organs.
Vd approximately 1.0 L/kg; indicates extensive tissue distribution, especially to reproductive organs and bone marrow.
Bioavailability of testosterone from Andro Gel is approximately 10-14% of the applied dose, due to limited skin permeation and first-pass metabolism (though minimal with transdermal route). For comparison, oral testosterone bioavailability is <1%, while intramuscular testosterone enanthate has 100% bioavailability.
Oral: 15–25% due to first-pass metabolism; buccal or transdermal: higher, but not commercially available for this formulation.
No specific dose adjustment is provided for renal impairment. Use with caution in patients with severe renal impairment due to potential for fluid retention.
No specific dose adjustment required based on GFR; caution in severe impairment (Cr Cl <30 m L/min) due to potential fluid retention.
Contraindicated in patients with Child-Pugh class C (severe hepatic impairment). Use with caution and monitor liver function in mild to moderate hepatic impairment; no specific dose reduction guidelines exist.
Contraindicated in Child-Pugh class B and C cirrhosis due to hepatotoxicity risk; in class A, use with caution and monitor liver function.
Not indicated in pediatric patients under 18 years of age; safety and efficacy have not been established.
Not recommended for use in children as it may cause premature epiphyseal closure and virilization; limited data.
Elderly patients may be more sensitive to androgens, and require careful monitoring for prostate enlargement, prostate cancer, and fluid retention. Start at the lowest dose (25 mg daily) and titrate based on serum testosterone levels and clinical response.
Increased risk of prostatic hyperplasia and carcinoma; use lowest effective dose with regular prostate monitoring.
None.
Warning: Prolonged use may cause virilization in women, premature epiphyseal closure, and increased risk of prostatic hypertrophy/carcinoma.
Risk of secondary exposure to testosterone (children) – avoid skin contact,Polycythemia (monitor hematocrit),Prostate enlargement/cancer risk,Cardiovascular risk (especially in elderly),Spermatogenesis suppression,Hepatic effects (monitor liver function),Edema (in patients with preexisting conditions)
Monitor liver function, lipid profile, and prostate-specific antigen; risk of edema in patients with cardiac disease; avoid use in patients with sleep apnea.
Known hypersensitivity to testosterone or gel components,Prostate cancer,Breast cancer (males),Women who are pregnant or may become pregnant (risk to fetus)
Known or suspected prostate cancer; breast cancer in males; hypersensitivity to androgens; pregnancy and lactation.
No specific food interactions. Grapefruit juice may increase testosterone levels due to CYP3A4 inhibition, but clinical significance is unclear. Avoid excessive alcohol intake as it may affect testosterone levels and liver function.
Avoid grapefruit and grapefruit juice as they may increase drug levels. Limit salt intake to reduce fluid retention. Alcohol may increase risk of liver toxicity.
Andro Gel (testosterone) is contraindicated in pregnancy. Testosterone is a teratogen with masculinization of female fetuses (clitoral enlargement, labial fusion, urogenital sinus abnormalities) when exposed during the first trimester. Second and third trimester exposure may cause pseudohermaphroditism in females. Risk is highest during the first 12 weeks of gestation.
Pregnancy Category X. ANDROID 5 (oxandrolone) is contraindicated in pregnancy due to teratogenic effects including masculinization of female fetus, clitoral enlargement, and labial fusion. Risk is highest during first trimester but applies throughout gestation.
Testosterone is excreted into breast milk with an estimated M/P ratio of 0.1-0.3. It may cause virilization in nursing infants. Breastfeeding is not recommended during Andro Gel therapy.
Excretion into human milk is unknown. Due to potential for androgenic effects in nursing infants, breastfeeding is not recommended. No M/P ratio available.
Andro Gel is contraindicated in pregnancy; no dose adjustments are applicable. If exposure occurs, discontinue immediately and monitor for fetal effects.
Not applicable; contraindicated in pregnancy. No dose adjustment recommendations exist for pregnant patients.
Apply to clean, dry, intact skin on shoulders, upper arms, or abdomen. Avoid application to genitals or chest due to higher absorption and risk of transfer. Wash hands after application. Allow gel to dry before dressing. Monitor serum testosterone, hematocrit, PSA, and lipid profile. Contraindicated in men with breast or prostate cancer. May cause erythrocytosis, sleep apnea, or worsening of BPH. Risk of testosterone transfer to women or children; cover application site or wash skin before contact.
Android 5 (methyltestosterone) is an androgenic anabolic steroid used for hypogonadism and delayed puberty. Monitor liver function due to hepatotoxicity. Use with caution in elderly due to increased risk of prostatic hypertrophy and carcinoma. Can cause fluid retention in patients with cardiac, renal, or hepatic disease. Avoid in patients with breast cancer or known or suspected prostate cancer.
Apply Andro Gel once daily at the same time each morning to clean, dry, intact skin on shoulders, upper arms, or abdomen.,Do not apply to genitals or chest.,Wash hands thoroughly with soap and water after application.,Allow gel to dry completely before dressing or coming into contact with others.,Avoid swimming, showering, or bathing for at least 5 hours after application.,If skin contact with another person is likely, cover the application site with clothing or wash the area before contact.,Keep Andro Gel away from children and women of childbearing potential.,Report any signs of deep vein thrombosis (leg swelling, pain, warmth), heart attack (chest pain, shortness of breath), or stroke (sudden weakness, confusion, vision changes).,Regular blood tests are required to monitor testosterone levels, red blood cell count, prostate health, and cholesterol.,Andro Gel may interact with blood thinners (e.g., warfarin) and corticosteroids; inform all healthcare providers.
