Choice of preparation
Aim to choose the lowest dosage of oestrogen and progestogen that:
- maintains efficacy
- has fewest side effects
- gives good cycle control
- takes into account differential risk of VTE
- is cost effective.
A monophasic COC containing 20 to 35 micrograms of ethinylestradiol with a low dose of either norethisterone or levonorgestrel is a suitable first line option. Examples are Rigevidon, Ovranette, Microgynon 30, Ovysmen and Brevinor. Tailored regimes may improve bleeding patterns and hence improve compliance. Please see FSRH Clinical Guideline: Combined Hormonal Contraception (January 2019, Amended October 2023) for alternative COC regimens. Transdermal or intravaginal preparations may be advantageous in situations where GI absorption is compromised, e.g. Inflammatory bowel disease, or in situations where this method will improve compliance.
