Overall ranking 27
JLA question ID 0049/27
Explanatory note These preparations exist, but are not licensed be for contraception in the UK. The uptake of the combined patch is relatively low (1.3 percent of women attending SRH clinics used this as their primary method) there are not overall prescription figures for the patch or ring in England.  Cost maybe a factor in accessing in HCP not prescribing these methods.
