🩺 Clinical
Testosterone topical is used to treat low or no testosterone levels in men. Testosterone is in a class of medications called androgenic hormones. Testosterone is a male sex hormone responsible for development and functioning of male sexual organs and typical male characteristics. Testosterone topical works by replacing the testosterone that is normally produced by the body.

⛔ Contraindications ▾
4 CONTRAINDICATIONS 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 ) 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 ( 5.4 ) 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 ( 5.1 ) and USE IN SPECIFIC POPULATIONS ( 8.1 )] .
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS 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 ( 5.4 ) 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 ( 5.1 ) 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. ( 5.3 ) 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 ( 5.4 , 5.2 , 5.9 , 5.13 ) Flammability: Testosterone gel 1.62% is flammable until dry ( 5.16 )
5.1Potential for Secondary Exposure to Testosterone Cases of secondary exposure resulting in virilization of children have been reported in postmarketing surveillance. Signs and symptoms have included enlargement of the penis or clitoris, development of pubic hair, increased erections and libido, aggressive behavior, and advanced bone age. In most cases, these signs and symptoms regressed with removal of the exposure to testosterone gel.
In a few cases, however, enlarged genitalia did not fully return to age-appropriate normal size, and bone age remained modestly greater than chronological age. The risk of transfer was increased in some of these cases by not adhering to precautions for the appropriate use of the topical testosterone product. Children and women should avoid contact with unwashed or unclothed application sites in men using testosterone gel 1.62% [see DOSAGE AND ADMINISTRATION ( 2.2 ), USE IN SPECIFIC POPULATIONS ( 8.1 ) and CLINICAL PHARMACOLOGY ( 12.3 )] .
Inappropriate changes in genital size or development of pubic hair or libido in children, or changes in body hair distribution, significant increase in acne, or other signs of virilization in adult women should be brought to the attention of a physician and the possibility of secondary exposure to testosterone gel should also be brought to the attention of a physician. Testosterone gel should be promptly discontinued until the cause of virilization has been identified.
5.2Polycythemia Increases in hematocrit, reflective of increases in red blood cell mass, may require lowering or discontinuation of testosterone. Check hematocrit prior to initiating treatment. It would also be appropriate to re-evaluate the hematocrit 3 to 6 months after starting treatment, and then annually.
If hematocrit becomes elevated, stop therapy until hematocrit decreases to an acceptable concentration. An increase in red blood cell mass may increase the risk of thromboembolic events.
5.3Venous Thromboembolism There have been postmarketing reports of venous thromboembolic events (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), in patients using testosterone products such as testosterone gel 1.62%. In the Testosterone Replacement therapy for Assessment of long-term Vascular Events and efficacy ResponSE in hypogonadal men (TRAVERSE) Study, a randomized, double-blind, placebo-controlled, cardiovascular (CV) out…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The most common adverse reaction (incidence ≥ 5%) is an increase in prostate specific antigen (PSA). ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Lupin Pharmaceuticals, Inc. at 1-800-399-2561 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Testosterone gel 1.62% was evaluated in a two-phase, 364-day, controlled clinical study. The first phase was a multi-center, randomized, double-blind, parallel-group, placebo-controlled period of 182 days, in which 234 hypogonadal men were treated with testosterone gel 1.62% and 40 received placebo.
Patients could continue in an open-label, non-comparative, maintenance period for an additional 182 days [see CLINICAL STUDIES ( 14.1 )] . The most common adverse reaction reported in the double-blind period was increased prostate specific antigen (PSA) reported in 26 testosterone gel 1.62%-treated patients (11.1%). In 17 patients, increased PSA was considered an adverse event by meeting one of the two pre-specified criteria for abnormal PSA values, defined as (1) average serum PSA >4 ng/mL based on two separate determinations, or (2) an average change from baseline in serum PSA of greater than 0.75 ng/mL on two determinations.
During the 182-day, double-blind period of the clinical trial, the mean change in serum PSA value was 0.14 ng/mL for patients receiving testosterone gel 1.62% and -0.12 ng/mL for the patients in the placebo group. During the double-blind period, seven patients had a PSA value >4.0 ng/mL, four of these seven patients had PSA less than or equal to 4.0 ng/mL upon repeat testing. The other three patients did not undergo repeat PSA testing.
During the 182-day, open-label period of the study, the mean change in serum PSA values was 0.10 ng/mL for both patients continuing on active therapy and patients transitioning onto active from placebo. During the open-label period, three patients had a serum PSA value > 4.0 ng/mL, two of whom had a serum PSA less than or equal to 4.0 ng/mL upon repeated testing. The other patient did not undergo repeat PSA testing.
Among previous placebo patients, 3 of 28 (10.7%), had increased PSA as an adverse event in the open-label period. Table 3 shows adverse reactions reported by >2% of patients in the 182-day, double-blind period of the testosterone gel 1.62% clinical trial and more frequent in the testosterone gel 1.62% treated group versus placebo. Table 3: Adverse Reactions Reported in >2% of Patients in the 182-Day, Double-Blind Period of Testosterone Gel 1.62% Clinical Trial Number (%) of Patients Adverse Reaction Testosterone Gel 1.62% N=234 Placebo N=40 PSA increased * 26 (11.1%) 0% Emotional lability ** 6 (2.6%) 0% Hypertension 5 (2.1%) 0% Hematocrit or hemoglobin increased 5 (2.1%) 0% Contact dermatitis *** 5 (2.1%) 0% * PSA increased includes: PSA values that met pre-specified criteria for abnormal PSA values (an average change from baseline > 0.75 ng/mL and/or an average PSA value >4.0 ng/mL based on two measurements) as well as those reported as adverse events. ** Emotional lability includes: mood swings, affective disorder, impatience, anger, and aggression. *** Contact dermatitis includes: 4 patients with dermatitis at non-application sites.
Other adverse reactions occurring in less than or equal to 2% of testosterone gel 1.62%-treated patients and more frequently than placebo included: frequent urination, and hyperlipidemia. In the open-label period of the study (N=191), the most commonly reported adverse reaction (experienced by greater than 2% of patients) was increased PSA (n=13; 6.2%) and sinusitis. Other adverse reactions reported by less than or equal to 2% of patients included increased hemoglobin or hemato…

7 DRUG INTERACTIONS Androgens may decrease blood glucose and therefore may decrease insulin requirements in diabetic patients ( 7.1 ) Changes in anticoagulant activity may be seen with androgens. More frequent monitoring of International Normalized Ratio (INR) and prothrombin time is recommended ( 7.2 ) Use of testosterone with adrenocorticotrophic hormone (ACTH) or corticosteroids may result in increased fluid retention. Use with caution, particularly in patients with cardiac, renal, or hepatic disease ( 7.3 )
7.1Insulin Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease insulin requirements.
7.2Oral Anticoagulants Changes in anticoagulant activity may be seen with androgens, therefore more frequent monitoring of international normalized ratio (INR) and prothrombin time are recommended in patients taking anticoagulants, especially at the initiation and termination of androgen therapy.
7.3Corticosteroids The concurrent use of testosterone with adrenocorticotropic hormone (ACTH) or corticosteroids may result in increased fluid retention and requires careful monitoring particularly in patients with cardiac, renal or hepatic disease.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS There are insufficient long-term safety data in geriatric patients using testosterone gel 1.62% to assess the potential risks of cardiovascular disease and prostate cancer. ( 8.5 )
8.1Pregnancy 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 Animal Data In developmental studies conducted in rats, rabbits, pigs, sheep and rhesus monkeys, pregnant animals received intramuscular injection of testosterone during the period of organogenesis.
Testosterone treatment at doses that were comparable to those used for testosterone replacement therapy resulted in structural impairments in both female and male offspring. Structural impairments observed in females included increased ano-genital distance, phallus development, empty scrotum, no external vagina, intrauterine growth retardation, reduced ovarian reserve, and increased ovarian follicular recruitment. Structural impairments seen in male offspring included increased testicular weight, larger seminal tubular lumen diameter, and higher frequency of occluded tubule lumen.
Increased pituitary weight was seen in both sexes. Testosterone exposure in utero also resulted in hormonal and behavioral changes in offspring. Hypertension was observed in pregnant female rats and their offspring exposed to doses approximately twice those used for testosterone replacement therapy.
8.2Lactation Risk Summary Testosterone gel 1.62% is not indicated for use in women.
8.3Females and Males of Reproductive Potential Infertility Testis disorder, testicular atrophy, and oligospermia have been identified during use of testosterone gel 1.62% [see ADVERSE REACTIONS ( 6.1 , 6.2 )] . During treatment with large doses of exogenous androgens, including testosterone gel 1.62%, spermatogenesis may be suppressed through feedback inhibition of the hypothalamic-pituitary-testicular axis [see WARNINGS AND PRECAUTIONS ( 5.8 )] . Reduced fertility is observed in some men taking testosterone replacement therapy.
Testicular atrophy, subfertility, and infertility have also been reported in men who abuse anabolic androgenic steroids [see DRUG ABUSE AND DEPENDENCE ( 9.2 )] . With either type of use, the impact on fertility may be irreversible.
8.4Pediatric Use The safety and effectiveness of testosterone gel 1.62% in pediatric patients less than 18 years old has not been established. Improper use may result in acceleration of bone age and premature closure of epiphyses.
8.5Geriatric Use There have not been sufficient numbers of geriatric patients involved in controlled clinical studies utilizing testosterone gel 1.62% to determine whether efficacy in those over 65 years of age differs from younger subjects. Of the 234 patients enrolled in the clinical trial utilizing testosterone gel 1.62%, 21 were over 65 years of age. Additionally, there is insufficient long-term safety data in geriatric patients to assess the potentially increased risks of cardiovascular disease and prostate cancer.
Geriatric patients treated with androgens may also be at risk for worsening of signs and symptoms of BPH.
8.6Renal Impairment No studies were conducted involving patients with renal impairment.
8.7Hepatic Impairment No studies were conducted in patients with hepatic impairment.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Endogenous androgens, including testosterone and dihydrotestosterone (DHT), are responsible for the normal growth and development of the male sex organs and for maintenance of secondary sex characteristics. These effects include the growth and maturation of prostate, seminal vesicles, penis and scrotum; the development of male hair distribution, such as facial, pubic, chest and axillary hair; laryngeal enlargement; vocal cord thickening; and alterations in body musculature and fat distribution.
Testosterone and DHT are necessary for the normal development of secondary sex characteristics. Male hypogonadism, a clinical syndrome resulting from insufficient secretion of testosterone, has two main etiologies. Primary hypogonadism is caused by defects of the gonads, such as Klinefelter's syndrome or Leydig cell aplasia, whereas secondary hypogonadism is the failure of the hypothalamus (or pituitary) to produce sufficient gonadotropins (FSH, LH).
12.2Pharmacodynamics No specific pharmacodynamic studies were conducted using testosterone gel 1.62%.
12.3Pharmacokinetics Absorption Testosterone gel 1.62% delivers physiologic amounts of testosterone, producing circulating testosterone concentrations that approximate normal levels (300 to 1000 ng/dL) seen in healthy men. Testosterone gel 1.62% provides continuous topical delivery of testosterone for 24 hours following once daily application to clean, dry, intact skin of the shoulders and upper arms. Average serum testosterone concentrations over 24 hours (C avg ) observed when testosterone gel 1.62% was applied to the upper arms/shoulders were comparable to average serum testosterone concentrations (C avg ) when testosterone gel 1.62% was applied using a rotation method utilizing the abdomen and upper arms/shoulders.
The rotation of abdomen and upper arms/shoulders was a method used in the pivotal clinical trial [see CLINICAL STUDIES ( 14.1 )]. Figure 2: Mean (±SD) Serum Total Testosterone Concentrations on Day 7 in Patients Following Testosterone Gel 1.62% Once-Daily Application of 81 mg of Testosterone (N=33) for 7 Days Distribution Circulating testosterone is primarily bound in the serum to sex hormone-binding globulin (SHBG) and albumin. Approximately 40% of testosterone in plasma is bound to SHBG, 2% remains unbound (free) and the rest is loosely bound to albumin and other proteins.
Metabolism Testosterone is metabolized to various 17-keto steroids through two different pathways. The major active metabolites of testosterone are estradiol and DHT. Excretion There is considerable variation in the half-life of testosterone concentration as reported in the literature, ranging from 10 to 100 minutes.
About 90% of a dose of testosterone given intramuscularly is excreted in the urine as glucuronic acid and sulfuric acid conjugates of testosterone and its metabolites. About 6% of a dose is excreted in the feces, mostly in the unconjugated form. Inactivation of testosterone occurs primarily in the liver.
When testosterone gel 1.62% treatment is discontinued, serum testosterone concentrations return to approximately baseline concentrations within 48 to 72 hours after administration of the last dose. Potential for testosterone transfer: The potential for testosterone transfer following administration of testosterone gel 1.62% when it was applied only to upper arms/shoulders was evaluated in two clinical studies of males dosed with testosterone gel 1.62% and their untreated female partners. In one study, 8 male subjects applied a single dose of testosterone gel 1.62% 81 mg to their shoulders and upper arms.
Two (2) hours after application, female subjects rubbed their hands, wrists, arms, and shoulders to the application site of the male subjects for 15 minutes. Serum concentrations of testosterone were monitored in female subjects for 24 hours after contact occurred. After direct skin-to-skin contact with the site of application, mean testoste…
