Drug interactions and hormonal contraception

Abstract

There are several classes/types of drugs that interact with hormonal contraception, which can increase or reduce the effectiveness of the contraception. Contraceptive hormones can also increase or decrease the safety and effectiveness of certain drugs the individual is taking. Therefore, it is important for any health professional who provides contraception to take a through drug history and check interactions before prescribing. Health professionals must ensure contraceptive consultations are thorough, and that these drug interactions are avoided to ensure optimum prescribing and unintended pregnancy. The Faculty of Sexual and Reproductive Health has updated its guidance on drug interactions with hormonal contraception, and this article provides a summary of this updated guidance, along with best practice points.
