Dosing & Administration

đŸ‘¨â€âš•ī¸

Adult Dosing

Standard Dose: Initial dose: 50 mg of testosterone (one 5 g packet of 1% gel or two 2.5 g packets of 1% gel) applied once daily to clean, dry, intact skin of the shoulders, upper arms, or abdomen. The 25mg packet is typically used for dose titration or as a lower starting dose.
Dose Range: 25 - 100 mg

Condition-Specific Dosing:

maleHypogonadism: Initial dose: 50 mg daily. Adjust dose based on serum testosterone levels and clinical response. The dose may be adjusted between 25 mg and 100 mg daily. Serum testosterone levels should be measured approximately 14 days after initiation of therapy or dose adjustment.
đŸ‘ļ

Pediatric Dosing

Neonatal: Not established
Infant: Not established
Child: Not established
Adolescent: Not established (Safety and efficacy not established in males under 18 years of age. Use in children is contraindicated due to risk of virilization in females and premature epiphyseal closure in males.)
âš•ī¸

Dose Adjustments

Renal Impairment:

Mild: No specific dose adjustment recommended, but caution advised.
Moderate: No specific dose adjustment recommended, but caution advised.
Severe: No specific dose adjustment recommended, but caution advised. Monitor for fluid retention.
Dialysis: Not available

Hepatic Impairment:

Mild: No specific dose adjustment recommended, but caution advised.

Pharmacology

đŸ”Ŧ

Mechanism 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. Testosterone acts by binding to androgen receptors in target tissues, where it is converted to DHT by 5-alpha reductase or aromatized to estradiol. These hormones then modulate gene expression, leading to androgenic effects.
📊

Pharmacokinetics

Absorption:

Bioavailability: Approximately 9-14% of applied testosterone is absorbed systemically. A transdermal reservoir is formed in the stratum corneum.
Tmax: Approximately 2-4 hours after application, with steady-state concentrations achieved within 2-4 days of daily application.
FoodEffect: Not applicable for topical gel.

Distribution:

Vd: Approximately 1 L/kg (for endogenous testosterone)
ProteinBinding: Approximately 98% bound to plasma proteins, primarily sex hormone-binding globulin (SHBG) and albumin.
CnssPenetration: Limited, but testosterone can cross the blood-brain barrier.

Elimination:

HalfLife: Approximately 10-100 minutes (for endogenous testosterone in plasma, but effective half-life from transdermal application is longer due to reservoir effect, leading to sustained levels over 24 hours).
Clearance: Approximately 10 mL/min/kg (for endogenous testosterone)
ExcretionRoute: Approximately 90% of a testosterone dose is excreted in the urine as glucuronic and sulfuric acid conjugates of testosterone and its metabolites; about 6% is excreted in the feces, mostly in the unconjugated form.
Unchanged: <6% (in urine)
âąī¸

Pharmacodynamics

OnsetOfAction: Within days to weeks for clinical effects (e.g., libido, energy). Serum testosterone levels reach steady-state within 2-4 days.
PeakEffect: Within 2-4 hours post-application for serum levels; clinical effects may take several weeks to months.
DurationOfAction: Approximately 24 hours (due to sustained release from skin reservoir).

Safety & Warnings

âš ī¸

BLACK BOX WARNING

WARNING: SECONDARY EXPOSURE TO TESTOSTERONE. Cases of secondary exposure resulting in virilization of children and women have been reported. Testosterone gel can transfer from the patient to other individuals upon direct contact. Patients should be advised to strictly adhere to recommended instructions for use, especially regarding application site, hand washing, and covering the application site.

🆘

Overdose Information

Overdose Symptoms:

  • High testosterone levels (above normal range)
  • Polycythemia (high red blood cell count, leading to symptoms like headache, dizziness, fatigue)
  • Fluid retention (edema)
  • Mood changes (irritability, aggression)
  • Acne
  • Hair loss

What to Do:

Discontinue testosterone gel and/or reduce the dose. Symptomatic and supportive treatment. Call 1-800-222-1222 (Poison Control Center) for advice.

Drug Interactions

🔴

Major Interactions

  • Anticoagulants (e.g., warfarin): May increase anticoagulant activity, leading to increased risk of bleeding. Monitor INR/PT closely.
  • Corticosteroids (e.g., prednisone): Concomitant use may increase the risk of edema, especially in patients with cardiac, renal, or hepatic disease.
🟡

Moderate Interactions

  • Insulin and oral hypoglycemic agents: Androgens may decrease blood glucose levels, potentially requiring a reduction in insulin or oral hypoglycemic dosage.
  • Thyroid hormones: May decrease levels of thyroid-binding globulin, leading to increased free thyroid hormone levels. No clinical significance usually, but monitor in patients on thyroid replacement.

Monitoring

đŸ”Ŧ

Baseline Monitoring

Serum Total Testosterone

Rationale: To confirm diagnosis of hypogonadism and establish baseline for dose titration.

Timing: Prior to initiation of therapy (morning levels, two separate measurements).

Prostate-Specific Antigen (PSA)

Rationale: To screen for pre-existing prostate cancer or benign prostatic hyperplasia (BPH) and monitor for prostate changes.

Timing: Prior to initiation of therapy (in men â‰Ĩ40 years with risk factors for prostate cancer, or â‰Ĩ50 years).

Hematocrit (Hct) and Hemoglobin (Hb)

Rationale: To assess for polycythemia, a common adverse effect of testosterone therapy.

Timing: Prior to initiation of therapy.

Lipid Panel

Rationale: To assess cardiovascular risk factors, as testosterone may affect lipid profiles.

Timing: Prior to initiation of therapy.

Liver Function Tests (LFTs)

Rationale: To assess baseline liver function, especially in patients with pre-existing hepatic impairment.

Timing: Prior to initiation of therapy.

📊

Routine Monitoring

Serum Total Testosterone

Frequency: Approximately 14 days after initiation or dose adjustment, then every 3-6 months once stable.

Target: 300-1000 ng/dL (or within the normal physiological range for healthy young men).

Action Threshold: If levels consistently above 1000 ng/dL, reduce dose or discontinue. If consistently below 300 ng/dL, consider dose increase.

Prostate-Specific Antigen (PSA)

Frequency: 3-6 months after initiation, then annually (or more frequently based on clinical judgment and risk factors).

Target: Stable or within age-appropriate normal limits.

Action Threshold: Significant increase from baseline or age-specific normal, or abnormal digital rectal exam (DRE), warrants urological evaluation.

Hematocrit (Hct)

Frequency: 3-6 months after initiation, then annually.

Target: <54%

Action Threshold: If Hct >54%, discontinue therapy until Hct decreases, then restart at a lower dose or consider phlebotomy.

Lipid Panel

Frequency: Annually or as clinically indicated.

Target: Within normal limits.

Action Threshold: Significant adverse changes may require intervention or re-evaluation of therapy.

Liver Function Tests (LFTs)

Frequency: As clinically indicated, especially if signs of hepatic dysfunction.

Target: Within normal limits.

Action Threshold: Significant elevations may require discontinuation.

đŸ‘ī¸

Symptom Monitoring

  • Signs of prostate enlargement (e.g., urinary hesitancy, frequency, nocturia)
  • Breast tenderness or enlargement (gynecomastia)
  • Fluid retention (edema, weight gain)
  • Mood changes, irritability, aggression
  • Sleep apnea (worsening or new onset)
  • Skin reactions at application site (redness, irritation, blistering)
  • Signs of secondary exposure in women or children (e.g., virilization in females, premature puberty in children)

Special Patient Groups

🤰

Pregnancy

Contraindicated in pregnant women. Testosterone is teratogenic and can cause virilization of a female fetus.

Trimester-Specific Risks:

First Trimester: High risk of virilization of female fetus.
Second Trimester: High risk of virilization of female fetus.
Third Trimester: High risk of virilization of female fetus.
🤱

Lactation

Contraindicated in breastfeeding women. It is unknown if testosterone is excreted in human milk, but due to the potential for serious adverse reactions in the breastfed infant, use is contraindicated.

Infant Risk: High risk of virilization and other serious adverse effects.
đŸ‘ļ

Pediatric Use

Contraindicated in children. Safety and efficacy have not been established. Use in children can cause premature epiphyseal closure and precocious puberty in males, and virilization in females.

👴

Geriatric Use

Use with caution in elderly men. Increased risk of benign prostatic hyperplasia (BPH) and prostate cancer. More frequent monitoring of PSA and DRE is recommended. Increased risk of cardiovascular events and polycythemia.
