Testosterone gel, 1.62% is indicated for replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone: Primary hypogonadism (congenital or acquired): testicular failure due to conditions such as cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, orchiectomy, Klinefelter's syndrome, chemotherapy, or toxic damage from alcohol or heavy metals. These men usually have low serum testosterone concentrations and gonadotropins (follicle-stimulating hormone [FSH], luteinizing hormone [LH]) above the normal range. Hypogonadotropic hypogonadism (congenital or acquired): gonadotropin or luteinizing hormone-releasing hormone (LHRH) deficiency or pituitary-hypothalamic injury from tumors, trauma, or radiation. These men have low testosterone serum concentrations, but have gonadotropins in the normal or low range. Limitations of use: Safety and efficacy of testosterone gel, 1.62% in men with “age-related hypogonadism” (also referred to as “late-onset hypogonadism”) have not been established. Safety and efficacy of testosterone gel, 1.62% in males less than 18 years old have not been established [see Use in Specific Populations ( 8.4 )] . Topical testosterone products may have different doses, strengths, or application instructions that may result in different systemic exposure [see Indications and Usage ( 1 ), and Clinical Pharmacology ( 12.3 )]. Testosterone gel, 1.62% is indicated for replacement therapy in males …

Testosterone gel, 1.62% is contraindicated in men with carcinoma of the breast or known or suspected carcinoma of the prostate [see Warnings and Precautions ( 5.1 ) and Adverse Reactions ( 6.1 )]. Testosterone gel, 1.62% is contraindicated in women who are pregnant. Testosterone gel, 1.62% can cause virilization of the female fetus when administered to a pregnant woman. Pregnant women need to be aware of the potential for transfer of testosterone from men treated with testosterone gel, 1.62%. If a pregnant woman is exposed to testosterone gel, 1.62%, she should be apprised of the potential hazard to the fetus [see Warnings and Precautions ( 5.2 ) and Use in Specific Populations ( 8.1 )] . Men with carcinoma of the breast or known or suspected prostate cancer ( 4 , 5.1 ) Women who are pregnant. Testosterone may cause fetal harm ( 4 , 8.1 )

Worsening of Benign Prostatic Hyperplasia (BPH) and Potential Risk of Prostate Cancer: Monitor patients with benign prostatic hyperplasia (BPH) for worsening of signs and symptoms of BPH. ( 5.1 ) Potential for Secondary Exposure to Testosterone: Avoid unintentional exposure of women or children to testosterone gel, 1.62%. Secondary exposure to testosterone can produce signs of virilization. Testosterone gel, 1.62% should be discontinued until the cause of virilization is identified. ( 5.2 ) Venous Thromboembolism (VTE): VTE, including deep vein thrombosis (DVT) and pulmonary embolism (PE) have been reported in patients using testosterone products. Evaluate patients with signs or symptoms consistent with DVT or PE. ( 5.4 ) Blood Pressure Increases: Testosterone gel, 1.62% can increase blood pressure, which can increase cardiovascular risk over time. Measure blood pressure periodically. Not recommended for use in men with uncontrolled hypertension ( 5.5 ) Potential for Adverse Effects on Spermatogenesis: Exogenous administration of androgens may lead to azoospermia. ( 5.8 ) Edema: Edema, with or without congestive heart failure (CHF), may be a complication in patients with preexisting cardiac, renal, or hepatic disease. ( 5.10 , 6.2 ) Sleep apnea: Sleep apnea may occur in those with risk factors. ( 5.12 ) Monitor serum testosterone, prostate specific antigen (PSA), hemoglobin, hematocrit, liver function tests, and lipid concentrations periodically. ( 5.1 , 5.3 , 5.9 , 5.13 ) …

8.1 Pregnancy Risk Summary Testosterone gel, 1.62% is contraindicated in pregnant women. Testosterone is teratogenic and may cause fetal harm when administered to a pregnant woman based on data from animal studies and its mechanism of action [see Contraindications ( 4 ) and Clinical Pharmacology ( 12.1 )] . Exposure of a female fetus to androgens may result in varying degrees of virilization. In animal developmental studies, exposure to testosterone in utero resulted in hormonal and behavioral changes in offspring and structural impairments of reproductive tissues in female and male offspring. These studies did not meet current standards for nonclinical development toxicity studies. Data …
