TESTIM® 1% (testosterone gel) | Free/Bioavailable Testosterone Calculator

Free/Bioavailable Testosterone Calculator

If a patient presents with symptoms that suggest low testosterone, a measurement of total testosterone is the best biochemical confirmation of hypogonadism. However, a bioavailable testosterone or free testosterone measurement can be useful to strengthen the confirmation, especially if the total testosterone level is borderline.¹ This calculator can be useful in estimating free and bioavailable testosterone levels.

Important Safety Information

WARNING: SECONDARY EXPOSURE TO TESTOSTERONE
Virilization has been reported in children who were secondarily exposed to testosterone gel. Children should avoid contact with unwashed or unclothed application sites in men using testosterone gel. Healthcare providers should advise patients to strictly adhere to recommended instructions for use.

Androgens are contraindicated in men with cancer of the breast or known or suspected cancer of the prostate. Testim is not indicated for women and must not be used in women. Pregnant and nursing women should avoid skin contact with Testim application sites on men. Testosterone may cause fetal harm, or harm a breast-feeding baby.

Testim should not be used in patients with known hypersensitivity to testosterone or any of the ingredients in Testim, including soy.

Men treated with androgens may be at an increased risk for prostate cancer, or the development or worsening of benign prostatic hyperplasia.

Testim is not meant for use in women. If you are pregnant, may become pregnant, or are breast-feeding, Testim may harm your unborn or breast-feeding baby. Women who are pregnant or who may become pregnant should avoid contact with the area where Testim has been applied.

Virilization can occur in women and children secondarily exposed to testosterone. To minimize the potential for secondary exposure to testosterone from Testim-treated skin, patients should wash their hands thoroughly and immediately with soap and water after application of Testim and should cover the application site(s) with clothing after the gel has dried. Prior to any situation in which direct skin-to-skin contact is anticipated, patients should wash the application sites thoroughly with soap and water so as to remove any testosterone residue.

Other risks associated with the use of testosterone include: edema with or without congestive heart failure, gynecomastia, and potentiation of sleep apnea. Large doses of testosterone may suppress spermatogenesis.

The most common adverse events occurring with the use of Testim include: application site reaction, increase in hematocrit/hemoglobin, headache, and increase in blood pressure.
