Androstenediol and Ethinyl Estradiol, Levonorgestrel

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ESTROGENS

Why this applies to Ethinyl Estradiol, Levonorgestrel

Ethinyl Estradiol, Levonorgestrel falls under ESTROGENS — the group Androstenediol interacts with.

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.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Your birth control pill (Levlite, Trivora, Triphasil and similar) contains ethinyl estradiol, a form of estrogen, paired with the progestin levonorgestrel. Androstenediol is a prohormone the body can turn into estrogen, so the worry here is mostly additive: piling on extra estrogen-like activity on top of the estrogen already in your pill. In theory that could bump up estrogen-related side effects like breast tenderness, nausea, bloating, mood changes, or headaches.

Honestly, this is a theoretical concern based on how these hormones work, not on solid studies, and the body tends to make less estrogen from androstenediol when your estrogen is already topped up. Still, since androstenediol carries real hormonal risks of its own, I'd talk with your pharmacist or doctor before combining the two.
