1. Purpose and scope
This document updates previous Faculty of Sexual & Reproductive Healthcare (FSRH) guidance and aims to summarise the available evidence and expert opinion on combined hormonal contraception (CHC). The guideline is intended for use by healthcare practitioners (HCPs) providing CHC.
2. Identification and assessment of the evidence
This guideline was developed in accordance with standard methodology for developing FSRH clinical guidelines. The recommendations made within this document are based on the best available evidence and the consensus opinion of experts and the guideline development group (GDG). The methodology used in developing this guideline and a list of GDG members and other contributors can be found in Appendix 1.
The recommendations included should be used to guide clinical practice but are not intended to serve alone as a standard of medical care or to replace clinical judgement in the management of individual cases.

HCPs should support women to make informed decisions about choosing and using CHC, ensuring that they are informed about contraceptive effectiveness (and how this compares to other contraceptive methods) as well as potential risks and benefits.
