This seventh edition has been completely revised and updated, incorporating relevant WHO and national guidance documents: therefore imparting best evidence-based practice for all methods.
- Combined oral contraceptives (COCs) Based on the long-established evidence that 7 days of routinely not-taking pills in each cycle is too long for maintained ovarian suppression - and this necessarily leads to too little margin for errors in pill-taking - the authors recommend that providers switch to a new norm for all users of either:
- Tricycling, the 84/4 regimen, or totally continuous use (365/365),
- OR, for women who remain keen to see monthly pill-bleeds (which are completely unnecessary for health), one of the regimens (24/4 or 21/4) that shorten the contraception-non-taking time to 4 days
- New methods, and their importance or otherwise:
