Clinical 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. Clinical Trials in Hypogonadal Men Table 2 shows the incidence of all adverse events judged by the investigator to be at least possibly related to treatment with AndroGel 1% and reported by > 1% of patients in a 180 Day, Phase 3 study.

**Prostate disorders included five patients with enlarged prostate, one with BPH, and one with elevated PSA results.
***Testis disorders were reported in two patients: one with left varicocele and one with slight sensitivity of left testis. Other less common adverse reactions, reported in fewer than 1% of patients included: amnesia, anxiety, discolored hair, dizziness, dry skin, hirsutism, hostility, impaired urination, paresthesia, penis disorder, peripheral edema, sweating, and vasodilation. In this 180 day clinical trial, skin reactions at the site of application were reported with AndroGel 1%, but none was severe enough to require treatment or discontinuation of drug. Six patients (4%) in this trial had adverse events that led to discontinuation of AndroGel 1%. These events included: cerebral hemorrhage, convulsion (neither of which were considered related to AndroGel 1% administration), depression, sadness, memory loss, elevated prostate specific antigen, and hypertension. No AndroGel 1% patient discontinued due to skin reactions. In a separate uncontrolled pharmacokinetic study of 10 patients, two had adverse events associated with AndroGel 1%; these were asthenia and depression in one patient and increased libido and hyperkinesia in the other. In a 3 year, flexible dose, extension study, the incidence of all adverse events judged by the investigator to be at least possibly related to treatment with AndroGel 1% and reported by > 1% of patients is shown in Table 3.

*Urinary symptoms included nocturia, urinary hesitancy, urinary incontinence, urinary retention, urinary urgency and weak urinary stream.
**Testis disorders included three patients. There were two with a non-palpable testis and one with slight right testicular tenderness. Two patients reported serious adverse events considered possibly related to treatment: deep vein thrombosis (DVT) and prostate disorder requiring a transurethral resection of the prostate (TURP). Discontinuation for adverse events in this study included: two patients with application site reactions, one with kidney failure, and five with prostate disorders (including increase in serum PSA in 4 patients, and increase in PSA with prostate enlargement in a fifth patient). Increases in Serum PSA Observed in Clinical Trials of Hypogonadal Men During the initial 6-month study, the mean change in PSA values had a statistically significant increase of 0.26 ng/mL. Serum PSA was measured every 6 months thereafter in the 162 hypogonadal men on AndroGel 1% in the 3-year extension study. There was no additional statistically significant increase observed in mean PSA from 6 months through 36 months. However, there were increases in serum PSA observed in approximately 18% of individual patients. The overall mean change from baseline in serum PSA values for the entire group from month 6 to 36 was 0.11 ng/mL. Twenty-nine patients (18%) met the per-protocol criterion for increase in serum PSA, defined as > 2X the baseline or any single serum PSA > 6 ng/mL. Most of these (25/29) met this criterion by at least doubling of their PSA from baseline. In most cases where PSA at least doubled (22/25), the maximum serum PSA value was still < 2 ng/mL. The first occurrence of a pre-specified, post-baseline increase in serum PSA was seen at or prior to Month 12 in most of the patients who met this criterion (23 of 29; 79%). Four patients met this criterion by having a serum PSA > 6 ng/mL and in these, maximum serum PSA values were 6.2 ng/mL, 6.6 ng/mL, 6.7 ng/mL, and 10.7 ng/mL. In two of these patients, prostate cancer was detected on biopsy. The first patient's PSA levels were 4.7 ng/mL and 6.2 ng/mL at baseline and at Month 6/Final, respectively. The second patient's PSA levels were 4.2 ng/mL, 5.2 ng/mL, 5.8 ng/mL, and 6.6 ng/mL at baseline, Month 6, Month 12, and Final, respectively. Postmarketing Experience The following adverse reactions have been identified during post approval use of AndroGel 1%. Because the reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure (Table 4). Table 4: Adverse Drug Reactions from Postmarketing Experience of AndroGel 1% by MedDRA System Organ Class
Blood and the lymphatic system disorders: Elevated Hgb, Hct (polycythemia) Cardiovascular disorders: Myocardial infarction, stroke Endocrine disorders: Hirsutism Gastrointestinal disorders: Nausea General disorders and administration site reactions: Asthenia, edema, malaise Genitourinary disorders: Impaired urination Hepatobiliary disorders: Abnormal liver function tests (e.g. transaminases, elevated GGTP, bilirubin) Investigations: Elevated PSA, electrolyte changes (nitrogen, calcium, potassium, phosphorus, sodium), changes in serum lipids (hyperlipidemia, elevated triglycerides, decreased HDL), impaired glucose tolerance, fluctuating testosterone concentrations, weight increase Neoplasms benign, malignant and unspecified (cysts and polyps): Prostate cancer Nervous system: Headache, dizziness, sleep apnea, insomnia Psychiatric disorders: Depression, emotional lability, decreased libido, nervousness, hostility, amnesia, anxiety Reproductive system and breast disorders: Gynecomastia, mastodynia, prostatic enlargement, testicular atrophy, oligospermia, priapism (frequent or prolonged erections) Respiratory disorders: Dyspnea Skin and subcutaneous tissue disorders: Acne, alopecia, application site reaction (pruritus, dry skin, erythema, rash, discolored hair, paresthesia), sweating Vascular disorders: Hypertension, vasodilation (hot flushes), venous thromboembolism Secondary Exposure to Testosterone in Children Cases of secondary exposure to testosterone resulting in virilization of children have been reported in postmarket surveillance. Signs and symptoms of these reported cases have included enlargement of the clitoris (with surgical intervention) or the penis, development of pubic hair, increased erections and libido, aggressive behavior, and advanced bone age. In most cases with a reported outcome, these signs and symptoms were reported to have regressed with removal of the testosterone gel exposure. 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. In some of the cases, direct contact with the sites of application on the skin of men using testosterone gel was reported. In at least one reported case, the reporter considered the possibility of secondary exposure from items such as the testosterone gel user's shirts and/or other fabric, such as towels and sheets [see WARNINGS AND PRECAUTIONS].

Dosage and Administration for AndroGel 1% differs from AndroGel 1.62%. For dosage and administration of AndroGel 1.62% refer to its full prescribing information. Prior to initiating AndroGel 1%, 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. Dosing And Dose Adjustment The recommended starting dose of AndroGel 1% is 50 mg of testosterone (4 pump actuations, two 25 mg packets, or one 50 mg packet), applied topically once daily in the morning to the shoulders and upper arms and/or abdomen area (preferably at the same time every day). Dose Adjustment To ensure proper dosing, serum testosterone concentrations should be measured at intervals. If the serum testosterone concentration is below the normal range, the daily AndroGel 1% dose may be increased from 50 mg to 75 mg and from 75 mg to 100 mg for adult males as instructed by the physician (see Table 1, Dosing Information for AndroGel 1%). If the serum testosterone concentration exceeds the normal range, the daily AndroGel 1% dose may be decreased. If the serum testosterone concentration consistently exceeds the normal range at a daily dose of 50 mg, AndroGel 1% therapy should be discontinued. In addition, serum testosterone concentrations should be assessed periodically. The application site and dose of AndroGel 1% are not interchangeable with other topical testosterone products. Administration Instructions AndroGel 1% should be applied to clean, dry, healthy, intact skin of the right and left upper arms/shoulders and/or right and left abdomen. Area of application should be limited to the area that will be covered by the patient's short sleeve T-shirt. Do not apply AndroGel 1% to any other part of the body including the genitals, chest, armpits (axillae), knees, or back. AndroGel 1% should be evenly distributed between the right and left upper arms/shoulders or both sides of the abdomen. The prescribed daily dose of AndroGel 1% should be applied to the right and left upper arms/shoulders and/or right/left abdomen as shown in the shaded areas in the figure below. After applying the gel, the application site should be allowed to dry prior to dressing. Hands should be washed thoroughly with soap and water after application. Avoid fire, flames or smoking until the gel has dried since alcohol based products, including AndroGel 1%, are flammable. The patient should be advised to avoid swimming or showering for at least 5 hours after the application of AndroGel 1%. Multi-Dose Pump To obtain a full first dose, it is necessary to prime the canister pump. To do so, with the canister in the upright position, slowly and fully depress the actuator three times. Safely discard the gel from the first three actuations. It is only necessary to prime the pump before the first dose. After the priming procedure, patients should completely depress the pump one time actuation for every 12.5 mg of testosterone required to achieve the daily prescribed dosage. The product should be delivered directly into the palm of the hand and then applied to the desired application sites. Alternatively, AndroGel 1% can be applied directly to the application sites. Table 1 provides dosing information for adult males. Table 1: Dosing Information for AndroGel 1%
Amount of Testosterone Number of Pump Actuations 50 mg 4 (once daily) 75 mg 6 (once daily) 100 mg 8 (once daily) Packets The entire contents should be squeezed into the palm of the hand and immediately applied to the application sites. Alternately, patients may squeeze a portion of the gel from the packet into the palm of the hand and apply to application sites. Repeat until entire contents have been applied. Strict adherence to the following precautions is advised in order to minimize the potential for secondary exposure to testosterone from AndroGel 1%-treated skin:
  • Children and women should avoid contact with unwashed or unclothed application site(s) of men using AndroGel 1%.
  • Patients should wash hands with soap and water immediately after application of AndroGel 1%.
  • Patients should cover the application site(s) with clothing (e.g., a T-shirt) after the gel has dried.
  • Prior to situation in which direct skin-to-skin contact is anticipated, patients should wash the application site thoroughly with soap and water to remove any testosterone residue.
  • In the event that unwashed or unclothed skin to which AndroGel 1% has been applied comes in direct contact with the skin of another person, the general area of contact on the other person should be washed with soap and water as soon as possible.

Insulin 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. Oral 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. Corticosteroids 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. Drug Abuse And Dependence Controlled Substance AndroGel 1% contains testosterone, a Schedule III controlled substance in the Controlled Substances Act. Abuse Anabolic steroids, such as testosterone, are abused. Abuse is often associated with adverse physical and psychological effects. Dependence Although drug dependence is not documented in individuals using therapeutic doses of anabolic steroids for approved indications, dependence is observed in some individuals abusing high doses of anabolic steroids. In general, anabolic steroid dependence is characterized by any three of the following:
  • Taking more drug than intended
  • Continued drug use despite medical and social problems
  • Significant time spent in obtaining adequate amounts of drug
  • Desire for anabolic steroids when supplies of the drugs are interrupted
  • Difficulty in discontinuing use of the drug despite desires and attempts to do so
  • Experience of a withdrawal syndrome upon discontinuation of anabolic steroid use

AndroGel 1% 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 AndroGel 1% in men with “age-related hypogonadism” (also referred to as “late-onset hypogonadism”) have not been established.
  • Safety and efficacy of AndroGel 1% in males less than 18 years old have not been established [see Use In Specific Populations].
  • Topical testosterone products may have different doses, strengths or application instructions that may result in different systemic exposure.

  • AndroGel 1% is contraindicated in men with carcinoma of the breast or known or suspected carcinoma of the prostate [see WARNINGS AND PRECAUTIONS, ADVERSE REACTIONS, and Nonclinical Toxicology].
  • AndroGel 1% is contraindicated in women who are or may become pregnant, or who are breastfeeding. AndroGel 1% may cause fetal harm when administered to a pregnant woman. AndroGel 1% may cause serious adverse reactions in nursing infants. Exposure of a female fetus or nursing infant to androgens may result in varying degrees of virilization. Pregnant women or those who may become pregnant need to be aware of the potential for transfer of testosterone from men treated with AndroGel 1%. If a pregnant woman is exposed to AndroGel 1%, she should be apprised of the potential hazard to the fetus [see WARNINGS AND PRECAUTIONS and Use In Specific Populations].

Worsening Of Benign Prostatic Hyperplasia (BPH) And Potential Risk Of Prostate Cancer
  • Patients with BPH treated with androgens are at an increased risk for worsening of signs and symptoms of BPH. Monitor patients with BPH for worsening signs and symptoms.
  • Patients treated with androgens may be at increased risk for prostate cancer. Evaluate patients for prostate cancer prior to initiating and during treatment with androgens [see CONTRAINDICATIONS, ADVERSE REACTIONS and Nonclinical Toxicology].
Potential 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 AndroGel 1% [see DOSAGE AND ADMINISTRATION, Use In Specific Populations and CLINICAL PHARMACOLOGY]. 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. Polycythemia 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. Venous Thromboembolism 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 AndroGel 1%. Evaluate patients who report symptoms of pain, edema, warmth and erythema in the lower extremity for DVT and those who present with acute shortness of breath for PE. If a venous thromboembolic event is suspected, discontinue treatment with AndroGel 1% and initiate appropriate workup and management [see ADVERSE REACTIONS]. Cardiovascular Risk Long term clinical safety trials have not been conducted to assess the cardiovascular outcomes of testosterone replacement therapy in men. To date, epidemiologic studies and randomized controlled trials have been inconclusive for determining the risk of major adverse cardiovascular events (MACE), such as non-fatal myocardial infarction, non-fatal stroke, and cardiovascular death, with the use of testosterone compared to non-use. Some studies, but not all, have reported an increased risk of MACE in association with use of testosterone replacement therapy in men. Patients should be informed of this possible risk when deciding whether to use or to continue to use AndroGel 1%. Use In Women Due to lack of controlled evaluations in women and potential virilizing effects, AndroGel 1% is not indicated for use in women [see CONTRAINDICATIONS and Use In Specific Populations]. Potential For Adverse Effects On Spermatogenesis With large doses of exogenous androgens, including AndroGel 1%, spermatogenesis may be suppressed through feedback inhibition of pituitary follicle-stimulating hormone (FSH) which could possibly lead to adverse effects on semen parameters including sperm count. Hepatic Adverse Effects Prolonged use of high doses of orally active 17-alpha-alkyl androgens (e.g., methyltestosterone) has been associated with serious hepatic adverse effects (peliosis hepatis, hepatic neoplasms, cholestatic hepatitis, and jaundice). Peliosis hepatis can be a life-threatening or fatal complication. Long-term therapy with intramuscular testosterone enanthate has produced multiple hepatic adenomas. AndroGel 1% is not known to cause these adverse effects. Edema Androgens, including AndroGel 1%, may promote retention of sodium and water. Edema, with or without congestive heart failure, may be a serious complication in patients with preexisting cardiac, renal, or hepatic disease [see ADVERSE REACTIONS]. Gynecomastia Gynecomastia may develop and persist in patients being treated with androgens, including AndroGel 1%, for hypogonadism. Sleep Apnea The treatment of hypogonadal men with testosterone may potentiate sleep apnea in some patients, especially those with risk factors such as obesity or chronic lung diseases [see ADVERSE REACTIONS]. Lipids Changes in serum lipid profile may require dose adjustment or discontinuation of testosterone therapy. Hypercalcemia Androgens, including AndroGel 1%, should be used with caution in cancer patients at risk of hypercalcemia (and associated hypercalciuria). Regular monitoring of serum calcium concentrations is recommended in these patients. Decreased Thyroxine-binding Globulin Androgens, including AndroGel 1%, may decrease concentrations of thyroxin-binding globulins, resulting in decreased total T4 serum concentrations and increased resin uptake of T3 and T4. Free thyroid hormone concentrations remain unchanged, however, and there is no clinical evidence of thyroid dysfunction. Flammability Alcohol based products, including AndroGel 1%, are flammable; therefore, patients should be advised to avoid fire, flame or smoking until the AndroGel 1% has dried. Patient Counseling Information See FDA-Approved Patient Labeling (Medication Guide) Patients should be informed of the following: Use In Men With Known Or Suspected Prostate Or Breast Cancer Men with known or suspected prostate or breast cancer should not use AndroGel 1% [see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS]. Potential For Secondary Exposure To Testosterone And Steps To Prevent Secondary Exposure Secondary exposure to testosterone in children and women can occur with the use of testosterone gel in men. Cases of secondary exposure to testosterone have been reported in children. Physicians should advise patients of the reported signs and symptoms of secondary exposure which may include the following:
  • In children; unexpected sexual development including inappropriate enlargement of the penis or clitoris, premature development of pubic hair, increased erections, and aggressive behavior
  • In women; changes in hair distribution, increase in acne, or other signs of testosterone effects
  • The possibility of secondary exposure to testosterone gel should be brought to the attention of a healthcare provider
  • AndroGel 1% should be promptly discontinued until the cause of virilization is identified
Strict adherence to the following precautions is advised to minimize the potential for secondary exposure to testosterone from testosterone gel in men [see Medication Guide]:
  • Children and women should avoid contact with unwashed or unclothed application site(s) of men using testosterone gel
  • Patients using AndroGel 1% should apply the product as directed and strictly adhere to the following:
    • Wash hands with soap and water after application
    • Cover the application site(s) with clothing after the gel has dried
    • Wash the application site(s) thoroughly with soap and water prior to any situation where skin-to-skin contact of the application site with another person is anticipated
    • In the event that unwashed or unclothed skin to which AndroGel 1% has been applied comes in contact with the skin of another person, the general area of contact on the other person should be washed with soap and water as soon as possible [see DOSAGE AND ADMINISTRATION, WARNINGS AND PRECAUTIONS and CLINICAL PHARMACOLOGY].
Potential Adverse Reactions With Androgens Patients should be informed that treatment with androgens may lead to adverse reactions which include:
  • Changes in urinary habits such as increased urination at night, trouble starting your urine stream, passing urine many times during the day, having an urge that you have to go to the bathroom right away, having a urine accident, being unable to pass urine and weak urine flow.
  • Breathing disturbances, including those associated with sleep, or excessive daytime sleepiness.
  • Too frequent or persistent erections of the penis.
  • Nausea, vomiting, changes in skin color, or ankle swelling.
Patients Should Be Advised Of The Following Instructions For Use:
  • Read the Medication Guide before starting AndroGel 1% therapy and to reread it each time the prescription is renewed
  • AndroGel 1% should be applied and used appropriately to maximize the benefits and to minimize the risk of secondary exposure in children and women
  • Keep AndroGel 1% out of the reach of children
  • AndroGel 1% is an alcohol based product and is flammable; therefore avoid fire, flame or smoking until the gel has dried
  • It is important to adhere to all recommended monitoring
  • Report any changes in their state of health, such as changes in urinary habits, breathing, sleep, and mood
  • AndroGel 1% is prescribed to meet the patient's specific needs; therefore, the patient should never share AndroGel 1% with anyone.
  • Wait 5 hours before swimming or washing following application of AndroGel 1%. This will ensure that the greatest amount of AndroGel 1% is absorbed into their system.
Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility Testosterone has been tested by subcutaneous injection and implantation in mice and rats. In mice, the implant induced cervical-uterine tumors which metastasized in some cases. There is suggestive evidence that injection of testosterone into some strains of female mice increases their susceptibility to hepatoma. Testosterone is also known to increase the number of tumors and decrease the degree of differentiation of chemically induced carcinomas of the liver in rats. Testosterone was negative in the in vitro Ames and in the in vivo mouse micronucleus assays. The administration of exogenous testosterone has been reported to suppress spermatogenesis in the rat, dog and non-human primates, which was reversible on cessation of the treatment. Use In Specific Populations Pregnancy Pregnancy Category X [see CONTRAINDICATIONS]: AndroGel 1% is contraindicated during pregnancy or in women who may become pregnant. Testosterone is teratogenic and may cause fetal harm. Exposure of a female fetus to androgens may result in varying degrees of virilization. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. Nursing Mothers Although it is not known how much testosterone transfers into human milk, AndroGel 1% is contraindicated in nursing women because of the potential for serious adverse reactions in nursing infants. Testosterone and other androgens may adversely affect lactation [see CONTRAINDICATIONS]. Pediatric Use The safety and efficacy of AndroGel 1% 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. Geriatric Use There have not been sufficient numbers of geriatric patients involved in controlled clinical studies utilizing AndroGel 1% to determine whether efficacy in those over 65 years of age differs from younger subjects. Additionally, there is insufficient long-term safety data in geriatric patients to assess the potential 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. Renal Impairment No studies were conducted in patients with renal impairment. Hepatic Impairment No studies were conducted in patients with hepatic impairment. Last reviewed on RxList: 6/4/2015
