If you are over 55 years of age, treatment with androgens (such as testosterone) may increase the risk of benign enlargement of the prostate and may promote the growth of existing cancer of the prostate. While using Androderm, some patients may experience skin irritation at the application site. To reduce the risk of such irritation, the patch should not be applied to the same place more than once a week. If irritation occurs and persists in spite of rotating the patch, it may be ameliorated by applying 0.1% triamcinolone acetonide cream. Androderm must not be used by women. Androderm should not be used by men who have breast cancer or by men who are suspected to have cancer of the prostate. Also, Androderm should not be used by men who are hypersensitive to any of the patch components. Adverse events reported by > 5% of patients in clinical trials of Androderm (n=122): pruritus at application site, 37%; burn-like blister reaction under system, 12%; erythema at application site, 7%; vesicles at application site, 6%; prostate abnormalities, 5%. In geriatric patients, treatment with testosterone may increase the risk of developing benign prostatic hyperplasia and may promote the growth of existing prostate cancer. Androderm should not be applied over bony prominences or over areas subject to prolonged pressure. Androderm must not be used in women.
