Interaction Details
Ethinyl estradiol, Levonogestrel is classified as belonging to the following category: Estrogens
Androstenediol is a precursor to estrogen and can increase levels of estradiol and estrone. There is some concern that taking androstenediol with estrogens might increase estrogenic effects and potential side effects. However, androstenediol is converted to estrogen in low estrogen environments. Patients who are taking supplemental estrogen do not have low estrogen levels. Therefore, androstenediol might not be converted to estrogen in these patients. It is unclear how this might alter the effects and side effects of androstenediol. Until more is known, use with caution or avoid using with estrogen-containing drugs. Some of these drugs include CombiPatch, Estraderm Transdermal, Kestrone, Vivelle Transdermal, and others.

Androstenediol Overview
Androstenediol is a naturally occurring steroid hormone in the body that serves as a precursor to testosterone and other androgens. It is classified as a prohormone and a weak anabolic steroid. Androstenediol is sometimes used in dietary supplements for its purported effects on increasing testosterone levels and enhancing athletic performance, although its effectiveness and safety for these purposes are not well-established. In the United States, androstenediol is listed as a Schedule III controlled substance, meaning it has a potential for abuse and dependence. It is also banned by organizations like the National Collegiate Athletic Association (NCAA) and the World Anti-Doping Agency (WADA) for use in sports competitions.
