Official title
Effect of the Addition of an Oral Androgen (Dehydroepiandrosterone) on Hepatic Globulins in Users of an Antiandrogenic Combined Oral Contraceptive (Ethinyl Estradiol/Drospirenone)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
A randomized study is to learn more about how a supplement called DHEA (dehydroepiandrosterone) affects clotting factors in women taking combined oral contraceptive pills. Current research suggests that the progestin hormone in a specific type of birth control pill may increase a woman's blood clot risk. However, it is unknown exactly how the progestin causes the increased risk. This study aims to learn if taking a daily dose of supplemental androgen (dehydroepiandrosterone, or DHEA) in addition to birth control pills containing DRSP affects proteins related to coagulation.
