🩺 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.

WARNING: SECONDARY EXPOSURE TO TESTOSTERONE See full prescribing information for complete boxed warning. Virilization has been reported in children who were secondarily exposed to testosterone gel ( 5.1 , 6.2 ) Children should avoid contact with unwashed or unclothed application sites in men using testosterone gel ( 2.2 , 5.1 ) Healthcare providers should advise patients to strictly adhere to recommended instructions for use ( 2.2 , 5.1 , 17 )
🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE TESTIM is indicated for testosterone 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 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 TESTIM in men with “age-related hypogonadism” (also referred to as “late-onset hypogonadism”) have not been established.
Safety and efficacy of TESTIM 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 Dosage and Administration ( 2 ) and Clinical Pharmacology ( 12.3 )] . TESTIM is an androgen indicated for testosterone replacement therapy in males for conditions associated with a deficiency or absence of endogenous testosterone: Primary Hypogonadism (Congenital or Acquired) ( 1 ) Hypogonadotropic Hypogonadism ( 1 ) Limitations of Use : Safety and efficacy of TESTIM in men with “age-related hypogonadism” have not been established.

⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Prior to initiating TESTIM, confirm the diagnosis of hypogonadism by ensuring that serum testosterone concentrations have been measured in the morning on at least two separate days and that these serum testosterone concentrations are below the normal range. Prior to initiating TESTIM, confirm the diagnosis of hypogonadism by ensuring that serum testosterone has been measured in the morning on at least two separate days and that these concentrations are below the normal range. ( 2 ) Recommended starting dose for adult males: 50 mg of testosterone (one tube) applied topically once daily.
( 2.1 ) Apply to clean, dry, intact skin of the shoulders and/or upper arms. Do NOT apply TESTIM to the genitals or abdomen. ( 2.1 , 2.2 ) If morning pre-dose serum testosterone concentration is below normal range, increase dose to 100 mg.
( 2.1 ) Pre-dose serum testosterone concentration should be assessed periodically. ( 2.1 ) Patients should wash hands with soap and water immediately after applying TESTIM and cover application site(s) with clothing after gel has dried. Wash the application site thoroughly with soap and water prior to any situation where skin-to-skin contact of the application site with another person is anticipated.
( 2.2 ) TESTIM is not substitutable with other topical testosterone products. ( 2.1 )
2.1Dosing and Dose Adjustment The recommended starting dose of TESTIM is 50 mg of testosterone (one tube) applied once daily (preferably in the morning) to clean, dry intact skin of the shoulders and/or upper arms. Dose Adjustment To ensure proper dosing, serum testosterone concentrations should be measured. Morning, pre-dose serum testosterone concentrations should be measured approximately 14 days after initiation of therapy to ensure proper serum testosterone concentrations are achieved.
If the serum testosterone concentration is below the normal range (300 ng/dL to 1,000 ng/dL), the daily TESTIM dose may be increased from 50 mg testosterone (one tube) to 100 mg testosterone (two tubes) once daily. The maximum recommended dose of TESTIM is 100 mg once daily. The application site and dose of TESTIM are not substitutable with other topical testosterone products.
2.2Administration Instructions Upon opening the tube the entire contents should be squeezed into the palm of the hand and immediately applied to the shoulders and/or upper arms (area of application should be limited to the area that will be covered by the patient’s short sleeve T-shirt ( see figure below ). Do not apply TESTIM to the genitals or to the abdomen. Application sites should be allowed to dry for a few minutes prior to dressing.
Hands should be washed thoroughly with soap and water after TESTIM has been applied. Avoid fire, flame or smoking during the application of TESTIM until the TESTIM has dried [see Warnings and Precautions ( 5.1 , 5.16 )] . In order to prevent transfer to another person, wear clothing to cover the application sites.
If direct skin-to-skin contact with another person is anticipated, the application sites must be washed thoroughly with soap and water [see Warnings and Precautions ( 5.1 ) and Clinical Pharmacology ( 12.3 )] . The patient should avoid swimming or showering or washing the administration site for a minimum of 2 hours after application [see Clinical Pharmacology ( 12.3 )] . Strict adherence to the following precautions is advised in order to minimize the potential for secondary exposure to testosterone from TESTIM-treated skin: Children and women should avoid contact with unwashed or unclothed application site(s) of men using TESTIM.
TESTIM should only be applied to the upper arms and shoulders. The area of application should be limited to the area that will be covered by a short sleeve T-shirt. Patients should wash their hands with soap and water immediately after applying TESTIM.
Patients should cover the application site(s) with clothing (e.g., a T-shirt) after the gel has dried. Prior to situat…

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Potential for Secondary Exposure to Testosterone: Avoid unintentional exposure of women or children to TESTIM. Secondary exposure to testosterone can produce signs of virilization. TESTIM 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 ) 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 ) Blood Pressure Increases: Testosterone 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 ) Abuse of Testosterone: Testosterone has been subject to abuse, typically at doses higher than recommended for the approved indication and in combination with other anabolic androgenic steroids ( 5.6 ).
Potential for Adverse Effects on Spermatogenesis Exogenous administration of androgens may lead to azoospermia. ( 5.8 ) Edema: Edema, with or without congestive heart failure, 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 prostate specific antigen (PSA), hematocrit, and lipid concentrations periodically. ( 5.2 , 5.4 , 5.13 ) TESTIM 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 TESTIM [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 (VTE) There have been postmarketing reports of venous thromboembolic events, including deep vein thrombosis (DVT) and pulmonary embolism (PE), in patients using testosterone products, such as TESTIM. In the Testosterone Replacement therapy for Assessment of long-term Vascular Events and efficacy ResponSE in hypogonadal men (TRAVERSE) Study, a randomized, double-blind,…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS Most common adverse reactions (incidence ≥ 2% of the TESTIM patients and greater than placebo) are application site reaction and increased hematocrit. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Endo at 1-800-462-3636 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Studies 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. In a controlled clinical study, 304 patients were treated with TESTIM 50 mg or 100 mg or placebo gel for up to 90 days. Two hundred five (205) patients received TESTIM 50 mg or 100 mg daily and 99 patients received placebo.
Subjects could be counted in both TESTIM treatment groups if they received both 50 mg and 100 mg at different points in the study and experienced an adverse reaction at both dose levels. Adverse reactions reported by ≥ 1% of the TESTIM patients and greater than placebo are listed in Table 1. Table 1: Incidence of Adverse Reactions (Reported by ≥ 1% of the TESTIM Patients and Greater than Placebo) in the Controlled Clinical Trial Through 90 Days Event TESTIM 50 mg (n=103) TESTIM 100 mg (n=149) Placebo (n=99) Application Site Reactions 2% 4% 3% Blood Pressure Increased 1% 1% 0% Gynecomastia 1% 0% 0% Headache 1% 1% 0% Hematocrit / hemoglobin Increased 1% 2% 0% Hot Flushes 1% 0% 0% Insomnia 1% 0% 0% Mood Swings 1% 0% 0% Smell Disorder 1% 0% 0% Spontaneous Penile Erection 1% 0% 0% Taste Disorder 1% 1% 0% The following adverse reactions occurred in fewer than 1% of patients but were greater in TESTIM groups compared to the placebo group: activated partial thromboplastin time prolonged, blood creatinine increased, prothrombin time prolonged, appetite increased, sensitive nipples, and acne.
In this clinical trial of TESTIM, 6 patients had adverse reactions that led to their discontinuation. These events included: depression with suicidal ideation, urinary tract infection, mood swings and hypertension. No TESTIM patients discontinued due to skin reaction.
In one foreign Phase 3 trial, one subject discontinued due to a skin-related adverse reaction. In the pivotal US and European Phase 3 trials combined, at the 50-mg dosage strength, the percentage of subjects reporting clinically notable increases in hematocrit or hemoglobin were similar to placebo. However, in the 100-mg dose group, 2.3% and 2.8% of patients had a clinically notable increase in hemoglobin (≥ 19 g/dL) or hematocrit (≥ 58%), respectively, compared to 1.0% and 1.5% of patients in the placebo group, respectively.
In the combined US and European open-label extension studies, approximately 140 patients received TESTIM for at least 6 months. The results from these studies are consistent with those reported for the US controlled clinical trial. Blood Pressure Increases In a 4-month clinical study, 24-hour ambulatory blood pressure monitoring (ABPM) was conducted on 225 patients.
ABPM was conducted at baseline and at Week 16 of TESTIM therapy. A total of 113 patients had acceptable ABPM recordings at both baseline and Week 16 and were at least 85% compliant with study drug. In that group, the mean change in 24-hour systolic blood pressure (BP) and diastolic BP from baseline to end-of-treatment at Week 16 (n=113) was 2.7 mm Hg (95% CI 0.7, 4.8) and 1.1 mm Hg (95% CI -0.1, 2.3), respectively.
In patients with a history of hypertension who were receiving antihypertensive therapy, the mean ABPM systolic and diastolic BP increased by 1.9 mm Hg [95% CI -1.4, 5.2] and 0.3 mm Hg [95% CI -1.6, 2.2], respectively [n=55]). In patients with no history of hypertension, the mean systolic and diastolic blood pressure increased by 2.2 mm Hg [95% CI -0.4, 4.9] and 1.1 mm Hg [95% CI -0.4, 2.7], respectively [n=56]. 3 patients (2.7%) on TESTIM, all of whom were receiving antihypertensive med…

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 in patients taking warfarin.
( 7.2 ) Use of testosterone with 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 necessitate a decrease in the dose of anti-diabetic medication.
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 warfarin, especially at the initiation and termination of androgen therapy.
7.3Corticosteroids The concurrent use of testosterone with 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 Geriatric Patients: There are insufficient long-term safety data to assess the potential risks of cardiovascular disease and prostate cancer. ( 8.5 )
8.1Pregnancy Risk Summary TESTIM is contraindicated in pregnant women. Testosterone is teratogenic and may cause fetal harm 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 development 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 anogenital 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 TESTIM is not indicated for use in females.
8.3Females and Males of Reproductive Potential Infertility During treatment with large doses of exogenous androgens, including TESTIM, spermatogenesis may be suppressed through feedback inhibition of the hypothalamic-pituitary-testicular axis [see Warnings and Precautions ( 5.8 )] , possible leading to adverse effects on semen parameters including sperm count. 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 TESTIM in pediatric patients less than 18 years old have not been established. Improper use may result in acceleration of bone age and premature closure of epiphyses.
8.5Geriatric Use There is insufficient long-term safety data in geriatric patients to assess the potentially increased risks of cardiovascular disease and prostate cancer [see Warnings and Precautions ( 5.4 )] .
8.6Renal Impairment No studies were conducted in patients with renal impairment.
8.7Hepatic Impairment No studies were conducted in patients with hepatic impairment.

This subject had serum testosterone concentrations of up to 11,400 ng/dL, which were implicated in a cerebrovascular accident.
Treatment of overdosage would consist of discontinuation of TESTIM, washing the application site with soap and water, and appropriate symptomatic and supportive care.
🧬 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 2 main etiologies. Primary hypogonadism is caused by defects of the gonads, such as Klinefelter's syndrome or Leydig cell aplasia, while secondary hypogonadism (hypogonadotropic hypogonadism) is the failure of the hypothalamus (or pituitary) to produce sufficient gonadotropins (FSH, LH).
12.2Pharmacodynamics No specific pharmacodynamic studies were conducted using TESTIM.
12.3Pharmacokinetics Absorption TESTIM (testosterone gel) delivers physiologic amounts of testosterone, producing circulating testosterone concentrations that approximate normal concentrations (e.g., 300 – 1000 ng/dL) seen in healthy men. The skin serves as a reservoir for the sustained release of testosterone into the systemic circulation. Approximately 10% of the testosterone applied on the skin surface is absorbed into the systemic circulation during a 24-hour period.
Single Dose In single-dose studies, when either TESTIM 50 mg or 100 mg was administered, absorption of testosterone into the blood continued for the entire 24-hour dosing period. Also, mean peak and average serum concentrations within the normal range were achieved within 24 hours. Multiple Dose With single daily applications of TESTIM 50 mg and 100 mg, follow-up measurements at 30 and 90 days after starting treatment have confirmed that serum testosterone and DHT concentrations are generally maintained within the normal range.
Figure 1 summarizes the 24-hour pharmacokinetic profile of testosterone for patients maintained on TESTIM 50 mg or TESTIM 100 mg for 30 days. Figure 1: Mean Steady-State Serum Testosterone (± SD) (ng/dL) Concentrations on Day 30 in Patients Applying TESTIM Once Daily The average daily testosterone concentration produced by TESTIM 100 mg at Day 30 was 612 (± 286) ng/dL and by TESTIM 50 mg at Day 30 was 365 (± 187) ng/dL. 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 2 different pathways. The major active metabolites of testosterone are estradiol and DHT.
The average daily DHT concentration produced by TESTIM 100 mg at Day 30 was 555 (± 293) pg/mL and by TESTIM 50 mg at Day 30 was 346 (± 212) pg/mL. Figure 2 summarizes the 24-hour pharmacokinetic profile of DHT for patients maintained on TESTIM 50 mg or TESTIM 100 mg for 30 days. Figure 2: Mean Steady-State Serum Dihydrotestosterone (± SD) (pg/mL) Concentrations on Day 30 in Patients Applying TESTIM Once Daily 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.
