What is Natesto?
From the FDA label:Natesto (testosterone) nasal gel is a slightly yellow gel containing 5.5 mg of testosterone in 122.5 mg of Natesto gel for nasal administration. The active pharmacologic ingredient in Natesto is testosterone, an androgen. Testosterone is a white to practically white crystalline powder chemically described as 17β-Hydroxyandrost-4-en-3-one. The structural formula is: The inactive ingredients are castor oil, oleoyl polyoxylglycerides, and colloidal silicon dioxide. Figure
How to use
Prior to initiating Natesto, 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 Natesto, 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 ). The recommended dose of Natesto is 11 mg of testosterone (2 pump actuations, one per nostril), applied intranasally three times daily. ( 2.1 ) Serum total testosterone concentrations should be checked periodically, starting as soon as one month after initiating treatment with Natesto. If total testosterone concentrations consistently exceed 1050 ng/dL, therapy with Natesto should be discontinued. If total testosterone concentrations are consistently below 300 ng/dL, an alternative treatment should be considered. ( 2.1 ) Not recommended for use with nasally administered drugs other than sympathomimetic decongestants (e.g., oxymetazoline). ( 2.3 , 7.4 , 12.3 ). 2.1. Dosing The recommended dose of Natesto is 11 mg of testosterone (2 pump actuations; 1 actuation per nostril) administered intranasally three times daily for a total daily dose of 33 mg. Serum total testosterone concentrations should be…
Side effects
Most common adverse reactions (incidence ≥3%) are: PSA increased, headache, rhinorrhea, epistaxis, nasal discomfort, nasopharyngitis, bronchitis, upper respiratory tract infection, sinusitis, and nasal scab. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Acerus Pharmaceuticals Corporation at 1-833-698-3786 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice. Natesto was evaluated in a multicenter, open-label, 90-day clinical study. Patients could continue treatment with Natesto in two, open-label extension periods for an additional 90 and 180 days, respectively. A total of 306 hypogonadal men with morning testosterone concentrations ≤ 300 ng/dL received Natesto. Of these, 78 received Natesto at a dose of 11 mg three times daily. 90-Day Clinical Study Among the 78 patients who received Natesto three times daily in the 90-day clinical study, the most common adverse reactions were: prostate specific antigen (PSA) increased, headache, rhinorrhea, epistaxis, nasal discomfort, nasopharyngitis, upper respiratory tract infection (URI), sinusitis, bronchitis and nasal scab. PSA increased…
Warnings
Important safety information
Nasal Adverse Reactions and Limited Long-Term Information on Nasal Safety: Instruct patients to report any nasal symptoms or signs ( 5.1 ) Not recommended for use in patients with chronic nasal conditions or alterations in nasal anatomy. ( 5.2 ) Venous Thromboembolism: 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 ) 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. ( 5.5 ) 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 ( 5.6 ) 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. ( 5.7 ) Potential for Adverse Effects on Spermatogenesis: Exogenous administration of androgens may lead to azoospermia ( 5.9 ) Edema: Edema with or without congestive heart failure (CHF) may be a complication in patients with preexisting cardiac, renal, or hepatic disease. ( 5.11 ) Sleep apnea: Sleep apnea may occur in those with risk factors. ( 5.13 ) Monitor prostate-specific antigen (PSA), hematocrit and lipid concentrations periodically. ( 5.5 , 5.3 , 5.14 ) 5.1 Nasal Adverse Reactions and Limited Long-Term Information on Nasal Safety Nasal adverse reactions, including nasopharyngitis, rhinorrhea, epistaxis, nasal discomfort and nasal scabbing, were reported in the clinical trial experience with Natesto. All nasal adverse reactions except one (a single case of upper respiratory infection) were reported as mild or moderate in severity; however, long-term clinical trial data on nasal safety is available in a limited number of subjects [ see Adverse Reactions ( 6.2 )] . Patients should be instructed to report any nasal symptoms or signs to their health care professional. In that circumstance, health care professionals should determine whether further evaluation (e.g., otorhinolaryngology consultation) or discontinuation of Natesto is appropriate. 5.2 Use in Patients with Chronic Nasal Conditions and Alterations in Nasal Anatomy Due to lack of clinical data on the safety or efficacy, Natesto is not recommended for use in the following patients: History of nasal disorders; History of nasal or sinus surgery; History of nasal fracture within the previous 6 months or nasal fracture that caused a deviated anterior nasal septum; Mucosal inflammatory disorders (e.g, Sjogren's syndrome); and Sinus disease. 5.3 Polycythemia Increases in hematocrit, reflective of increases in red blood cell mass, may require discontinuation of Natesto. Check hematocrit prior to initiating testosterone treatment. It would be appropriate to re-evaluate the hematocrit 3 to 6 months after starting testosterone treatment, and then annually. If hematocrit becomes elevated, stop therapy until hematocrit decreases to an acceptable level. An increase in red blood cell mass may increase the risk of thromboembolic events. 5.4 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 Natesto. 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 Natesto and initiate appropriate workup and management [see Adverse Reactions ( 6.2 )]. 5.5 Worsening of Benign Prostatic Hyperplasia 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 treatment. It would be appropriate to re-evaluate patients 3 to 6 months after initiation of treatment and then in accordance with prostate cancer screening practices [see Contraindications (4) ]. 5.6 Blood Pressure Increases Testosterone products, such as Natesto, can increase blood pressure. Blood pressure increases can increase cardiovascular (CV) risk over time. The CV risk associated with topical testosterone gel was evaluated in TRAVERSE, 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 Natesto, especially men with hypertension. Natesto is not recommended for use in patients with uncontrolled hypertension. 5.7 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. 5.8 Not for Use in Women Due to lack of controlled studies in women and potential virilizing effects, Natesto is not indicated for use in women. 5.9 Potential for Adverse Effects on Spermatogenesis With large doses of exogenous androgens, including Natesto, 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. 5.10 Hepatic Adverse Effects Prolonged use of high doses of orally active 17-alpha-alkyl androgens (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. Natesto is not known to cause these adverse effects. Nonetheless, patients should be instructed to report any signs or symptoms of hepatic dysfunction (e.g., jaundice).…
Who should not take Natesto
Natesto is contraindicated in men with carcinoma of the breast or known or suspected carcinoma of the prostate [ see Warnings and Precaution ( 5.5 )]. Natesto is contraindicated in women who are or who may become pregnant, or who are breast- feeding. Natesto may cause fetal harm when administered to a pregnant woman. Natesto may cause serious adverse reactions in nursing infants. Exposure of a fetus or nursing infant to androgens may result in varying degrees of virilization. If a pregnant woman is exposed to Natesto, she should be apprised of the potential hazard to the fetus [ see Warnings and Precautions ( 5.8 ) and Use in Specific Populations ( 8.1 , 8.3 )]. Men with carcinoma of the breast or known or suspected prostate cancer ( 4 , 5.5 ) Pregnant or breast-feeding women. Testosterone may cause fetal harm ( 4 , 8.1 )
Overdose — what happens if you take too much
No cases of overdose with Natesto have been reported in clinical trials. There is 1 report of acute overdosage by injection of testosterone enanthate: testosterone concentrations of up to 11,400 ng/dL were implicated in a cerebrovascular accident. Treatment of overdosage would consist of discontinuation of Natesto together with 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 ration (INR) and prothrombin time is 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 monitoring particularly in patients with cardiac, renal, or hepatic disease. 7.4 Oxymetazoline A 2.6% decrease in mean AUC(0-24) and 3.6% decrease in mean C max of total testosterone was observed in males with symptomatic seasonal rhinitis when treated with oxymetazoline 30 minutes prior to Natesto compared to when left untreated. Oxymetazoline does not impact the absorption of testosterone when concomitantly administered with Natesto [see Clinical Pharmacology ( 12.3 )] . Drug interaction potential with other nasally administered drugs other than oxymetazoline has not been studied.
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 Natesto treat?
- Natesto (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 Natesto work?
- Natesto 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 Natesto cost?
