COCP MOA
prevents ovulation progesterone thickens mucusprogesterons recued endometrial proliferation
2 types of COCP
monophasic (same amount of hormone in each pill)| multiphasic (varying amounts of hormone to match normal cyclical changes)
COCP with lower risk of VTE
progesterone as levonorgester or norethisterone
1st line COCP for PMS
Yasmin - the ones with drospirenone (help with water retention, bloating, modd changes)
COCP in treatemtn of acne/hirsutism
Dianette - with cuproterone acetate, but high risk of VTE
COCP benefits
improves PMS, menorrhagia, dysmenorrhoea, reduced risk of endometrial , ovarian, colon cancer
starting COCP
no additional contraception if starting in 1st 5 days of cycleif after 5 days, requres extra contraception for 7 days
how to switch COCPs?

swithing from POP to COCP
switch at any time but 7days extra contracceptionunless switching from desogestrel which inhibits ovulation, then no extras
when to stop COCP
4 weeks before major operation

POP MOA
Thickening the cervical mucusAltering the endometrium and making it less accepting of implantationReducing ciliary action in the fallopian tubes
starting POP
if starting on days 1-5 no extrasif after day 5, additional contraception is required for 48h.if switching from POP - extra contraception for 48h (best to switch during hormone free period)
