Drug interactions
Guidance on antibiotics and contraceptive pill interaction changed GPs have been given the goahead to prescribe almost all classes of antibiotics to women who take the contraceptive pill, in a major change to current practice prompted by new evidence on the interactions between the drugs.
NICE - Key Priorities for Implementation Women requiring contraception should be given information about and offered a choice of all methods, including LARCs. All IUD/IUS/depo/implant are more cost effective than the COC even at 1 year of use IUD/IUS/implants are more cost effective than depo - provera Increasing the uptake of LARCs will reduce the numbers of unintended pregnancies.
