What is Testim?
From the FDA label:TESTIM (testosterone gel) is a clear to translucent hydroalcoholic topical gel containing testosterone, an androgen. TESTIM provides continuous transdermal delivery of testosterone for 24 hours, following a single application to intact, clean, dry skin of the shoulders and/or upper arms. One 5-g or two 5-g tubes of TESTIM contains 50 mg or 100 mg of testosterone, respectively, to be applied daily to the skin’s surface. Approximately 10% of the applied testosterone dose is absorbed across skin of average permeability during a 24-hour period. The active pharmacological ingredient in TESTIM is testosterone. Testosterone USP is a white to practically white crystalline powder chemically described as 17-β hydroxyandrost-4-en-3-one. The structural formula is shown in the following figure: Testim may have an alcoholic/musk odor. Inactive ingredients in TESTIM are purified water, pentadecalactone, carbopol, acrylates, propylene glycol, glycerin, polyethylene glycol, ethanol (74%), and tromethamine.

How to use
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 ) 2.1 Dosing and Dose Adjustment The recommended starting dose of TESTIM is 50…
Side effects
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 . 6.1 Clinical 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.

FDA Boxed Warning (the FDA’s most serious warning)
Boxed (black-box) warning — from the FDA label
Virilization has been reported in children who were secondarily exposed to testosterone gel [see Warnings and Precautions ( 5.1 ) and Adverse Reactions ( 6.2 )] . Children should avoid contact with unwashed or unclothed application sites in men using testosterone gel [see Dosage and Administration ( 2.2 ) and Warnings and Precautions ( 5.1 )]. Healthcare providers should advise patients to strictly adhere to recommended instructions for use [see Dosage and Administration ( 2.2 ), Warnings and Precautions ( 5.1 ), and Patient Counseling Information ( 17 )]. 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 )
Warnings
Important safety information
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 ) 5.1 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 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. 5.2 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. 5.3 Venous 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, placebo-controlled, cardiovascular (CV) outcomes study, compared to placebo, topical testosterone gel was associated with a numerically higher incidence of VTE (1.7% vs 1.2%) which included DVT (0.6% vs 0.5%) and PE events (0.9% vs 0.5%) [see Adverse Reactions ( 6.1 )]. 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 TESTIM and initiate appropriate workup and management [see Adverse Reactions ( 6.2 )] . 5.4 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 ( 4 )] . 5.5 Blood Pressure Increases TESTIM can increase blood pressure. In an ambulatory blood pressure monitoring (ABPM) study, TESTIM increased the mean systolic/diastolic blood pressure by 2.7/1.1 mm Hg from baseline after 16 weeks of treatment. In patients with hypertension on antihypertensive therapy, TESTIM increased the mean systolic/diastolic BP by 1.9/0.3 mm Hg from baseline. Blood pressure increases can increase cardiovascular (CV) risk over time. The CV risk associated with topical testosterone gel was evaluated in TRAVERSE, a randomized, double-blind, placebo-controlled, CV outcomes study in men with a history of CV disease or multiple CV risk factors. In TRAVERSE, topical testosterone gel increased mean systolic blood pressure by 1.0 mm Hg from baseline to 36 months, whereas a mean decrease from baseline of 0.5 mm Hg was observed in the placebo group at this timepoint, for a mean between-group difference of 1.5 mm Hg. However, the incidences of major adverse cardiovascular events (MACE), including cardiovascular death, non-fatal myocardial infarction [MI] and non-fatal stroke, were similar between treatment groups (7% for topical testosterone gel vs 7.3% for placebo) [See Adverse Reactions ( 6.1 )]. Monitor blood pressure periodically in men using TESTIM, especially men with hypertension. TESTIM is not recommended for use in patients with uncontrolled hypertension. 5.6 Abuse of Testosterone and Monitoring of Serum Testosterone Concentrations Testosterone has been subject to abuse, typically at doses higher than recommended for the approved indication and in combination with other anabolic androgenic steroids. Anabolic androgenic steroid abuse can lead to serious cardiovascular and psychiatric adverse reactions [see Drug Abuse and Dependence ( 9 )]. If testosterone abuse is suspected, check serum testosterone concentrations to ensure they are within therapeutic range. However, testosterone levels may be in the normal or subnormal range in men abusing synthetic testosterone derivatives. Counsel patients concerning the serious adverse reactions associated with abuse of testosterone and anabolic androgenic steroids. Conversely, consider the possibility of testosterone and anabolic androgenic steroid abuse in suspected patients who present with serious cardiovascular or psychiatric adverse events. 5.7 Not for Use in Women Due to lack of controlled evaluations in women and potential virilizing effects, TESTIM is not indicated for use in women [see Contraindications ( 4 ) and Use in Specific Populations ( 8.1 , 8.2 )] . 5.8 Potential for Adverse Effects on Spermatogenesis With large doses of exogenous androgens, including TESTIM, 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. 5.9 Hepatic Adverse Effects Prolonged use of high doses of orally active 17-alpha-alkyl…
Who should not take Testim
TESTIM is contraindicated in men with carcinoma of the breast or known or suspected carcinoma of the prostate [see Warnings and Precautions ( 5.4 )] . TESTIM is contraindicated in women who are pregnant. Testosterone can cause virilization of the female fetus when administered to a pregnant woman [see Use in Specific Populations ( 8.1 , 8.2 )] . Men with known carcinoma of the breast or known or suspected carcinoma of the prostate. ( 4 , 5.4 ) Women who are pregnant. Testosterone may cause fetal harm. ( 4 , 5.7 , 8.1 , 8.2 )
Overdose — what happens if you take too much
There were no reports of overdose in the TESTIM clinical trials. There is a single report in the literature of acute overdosage after injection of testosterone enanthate. 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.

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 ) 7.1 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 necessitate a decrease in the dose of anti-diabetic medication. 7.2 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 warfarin, especially at the initiation and termination of androgen therapy. 7.3 Corticosteroids 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.
How long does Testosterone stay in your body?
The elimination half-life of testosterone is about 10 to 100 minutes — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. This is the half-life of the natural testosterone hormone itself. The FDA label notes "considerable variation... ranging from 10 to 100 minutes," reflecting how quickly free testosterone is cleared. Two caveats matter for "how long it stays in your system": (1) Formulation dominates. Injectable esters are slow-release depots that far outlast the hormone's own half-life — testosterone cypionate ~8 days, enanthate ~4.5 days, undecanoate weeks — and oral testosterone undecanoate (Jatenzo, Kyzatrex) is a prodrug cleaved to testosterone. The 10-100 minute figure is the hormone's intrinsic clearance, not the duration of a shot. (2) Testosterone converts to active metabolites — dihydrotestosterone (DHT) and estradiol — that circulate on their own timelines. Inactivation occurs primarily in the liver, so hepatic impairment can slow clearance; ~90% is excreted in urine as conjugates. Half-life is not the drug-test detection window: anti-doping tests use the testosterone/epitestosterone ratio and isotope analysis and can flag use for far longer than clearance of the hormone.

Frequently asked questions
- What does Testim treat?
- Testim (Testosterone) may be used to treat breast neoplasms, hypogonadism, delayed puberty, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
- How does Testim work?
- Testim is a androgen. Androgens such as testosterone are male sex hormones that enter cells and bind the androgen receptor, switching on genes that drive male traits, muscle and bone growth, and reproductive function. Some testosterone is also converted in tissues to the more potent DHT.
- How much does Testim cost?
- Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $0.65 per gm, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.
- Is there a coupon or discount for Testim?
- pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Testim.
