Women should not use Testred (methyltestosterone capsules) during pregnancy, as it may cause masculinization of the genitals in female fetuses. Due to the potential risks to an unborn child, this product is classified as a pregnancy Category X medicine, which means the risks outweigh any potential benefits. If you are or could become pregnant, do not use Testred.
Can Pregnant Women Take Testred?Testred® (methyltestosterone capsules) is a prescription medication used for testosterone replacement therapy. Because it contains a form of testosterone, Testred is not safe for use by pregnant women in any situation. This drug is most often used in men and is approved for women only for the treatment of certain cases of late-stage breast cancer.
What Is Pregnancy Category X?The U.S. Food and Drug Administration (FDA) uses a system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category X is given to medicines that show problems to the fetus in animal studies or in humans who have mistakenly taken the medicine.
Because it would be unethical to give Testred to pregnant women, the use of this drug during pregnancy has never been studied in a clinical trial. However, we know about the problems Testred might cause based on problems seen with methyltestosterone or other androgens given to pregnant animals and based on a few cases of testosterone exposure in pregnant women.
When pregnant animals or women are exposed to androgens like Testred, there is a definite risk for masculinization of the genitals in female fetuses. The risk for the most dramatic changes occurs with early first-trimester exposure, although exposure at any time during pregnancy can cause some genital changes.
