Overdose Information
Overdose Symptoms:
- Symptoms of excessive androgen exposure may include irritability, acne, oily skin, hair loss, or increased body hair.
- No specific antidote for testosterone overdose.
What to Do:
If you suspect an overdose, seek immediate medical attention or call a Poison Control Center at 1-800-222-1222. Treatment is supportive and symptomatic; discontinue the medication and monitor testosterone levels.
Drug Interactions
Contraindicated Interactions
- Not typically contraindicated with other drugs, but caution with severe hepatic impairment.
Major Interactions
- Oral 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 Hypoglycemics: Androgens may decrease blood glucose levels, potentially reducing insulin or oral hypoglycemic requirements. Monitor blood glucose.
- Thyroid Hormones: Androgens may decrease levels of thyroid-binding globulin, resulting in decreased total T4 serum levels and increased resin uptake of T3 and T4. Free thyroid hormone levels remain unchanged. Clinical significance is usually minimal, but monitor thyroid function if clinically indicated.
Minor Interactions
- Not typically listed as minor interactions with significant clinical impact.
Monitoring
Baseline Monitoring
Rationale: To confirm diagnosis of hypogonadism and establish baseline levels.
Timing: Prior to initiation of therapy (usually two morning measurements).
Rationale: To assess for polycythemia, a common side effect of testosterone therapy.
Timing: Prior to initiation of therapy.
Rationale: To screen for prostate cancer in men aged 40 and older, as testosterone can stimulate prostate growth.
Timing: Prior to initiation of therapy (in men âĨ40 years old).
Rationale: To assess cardiovascular risk factors, as testosterone therapy may affect lipid profiles.
Timing: Prior to initiation of therapy.
Rationale: To assess baseline liver function, especially given potential for hepatic effects.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Approximately 14 days after initiation or dose adjustment, then every 3-6 months for the first year, then annually.
Target: Generally 300-1000 ng/dL (or within the mid-normal range for healthy young men).
Action Threshold: If levels are consistently above 1000 ng/dL, reduce dose or discontinue. If levels are consistently below 300 ng/dL, consider dose increase.
Frequency: At 3 and 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.
Frequency: At 3-6 months after initiation, then annually (in men âĨ40 years old).
Target: Stable or within normal limits for age.
Action Threshold: Significant increase from baseline or age-specific normal range, or abnormal prostate exam, warrants further urological evaluation.
Frequency: Annually.
Target: Within normal limits.
Action Threshold: Significant adverse changes may require intervention or re-evaluation of therapy.
Frequency: Consider for men with osteoporosis or high fracture risk, especially if hypogonadism is long-standing.
Target: Improvement or stabilization.
Action Threshold: Not applicable for dose adjustment, but for overall management.
Symptom Monitoring
- Signs of virilization in women or children (e.g., voice deepening, hirsutism, clitoromegaly, premature puberty) in household contacts.
- Signs of prostate enlargement (e.g., urinary hesitancy, frequency, nocturia, decreased stream).
- Signs of fluid retention (e.g., ankle swelling, weight gain).
- Signs of deep vein thrombosis (DVT) or pulmonary embolism (PE) (e.g., leg pain/swelling, shortness of breath, chest pain).
- Mood changes, irritability, aggression.
- Sleep apnea (worsening or new onset).
- Breast tenderness or enlargement (gynecomastia).
Special Patient Groups
Pregnancy
Contraindicated. Testosterone is classified as Pregnancy Category X. It can cause fetal harm when administered to a pregnant woman. Exposure to androgens during pregnancy may lead to virilization of the external genitalia of a female fetus.
Trimester-Specific Risks:
Lactation
Contraindicated. It is not known whether testosterone is excreted in human milk. However, due to the potential for serious adverse reactions in the breastfed infant, including virilization, testosterone is contraindicated during breastfeeding. Women should not breastfeed while using Androgel 1.62%.
Pediatric Use
Not indicated for use in pediatric patients. Use in children can cause virilization (e.g., phallic enlargement, premature development of pubic hair, increased libido) and premature epiphyseal closure, resulting in compromised adult height. Safety and efficacy have not been established.
Geriatric Use
Geriatric patients treated with androgen therapy may be at an increased risk for the development of prostate hypertrophy and prostate carcinoma. Increased risk of cardiovascular events (e.g., MI, stroke) has been reported in some studies, particularly in older men. Close monitoring for prostate health and cardiovascular risk factors is essential.
Clinical Information
Clinical Pearls
- Emphasize the critical importance of proper application technique and adherence to instructions to prevent secondary testosterone transfer to women and children, which can cause serious adverse effects.
- Patients should be advised to wash hands thoroughly after application and cover the application site with clothing once dry.
- Regular monitoring of serum testosterone, hematocrit, and PSA is crucial for safe and effective therapy.
- Be aware of the potential for fluid retention, especially in patients with pre-existing cardiac, renal, or hepatic disease.
- Counsel patients on the signs and symptoms of polycythemia, prostate enlargement, and potential cardiovascular events.
- Androgel 1.62% is designed to deliver a consistent daily dose; do not apply more than the prescribed amount or to areas other than recommended.
Alternative Therapies
- Other topical testosterone formulations (e.g., patches, other gels like Testim, Fortesta, Vogelxo)
- Testosterone injections (e.g., testosterone cypionate, enanthate)
- Testosterone buccal system (Striant)
- Testosterone pellets (Testopel)
- Testosterone nasal gel (Natesto)
