Check at a glance how to change contraceptive methods with the intelog table 'Switching to and between combined hormonal contraception'.
The table explains when to start combined hormonal contraception (CHC) after switching from:
- another type of CHC (pill, patch or ring)
- a traditional progesterone-only pill or levonorgestrel-releasing IUS
- progesterone-only anovulatory methods (implant, injection or desogestrel-only pill)
- non-hormonal methods including IUDs
The need for additional contraceptive precautions is noted in each case.
The recommendations are taken from the Faculty of Sexual and Reproductive Healthcare's guideline on combined hormonal contraception.
