Pearl index Method Failure %rates per hundred women years • Sterilisation male 0.0 to 0.2 • Sterilisation female0.0 to 0.3 (1.8% at 10 years) • Implanon0.0 • Mirena0.0 to 0.2 • Depo-Proverax0.0 to 0.2 • Combined oral contraceptive pill0.2 to 3 (3 with poor compliance) • Progestogen-only pill (second generation)0.3 to 4 (0.5 over age 35) • IUDs 0.3 to 2 • Diaphragm/cervical • Cap 5 to 20 • Condom (male, female) 5 to 15 • Coitus interruptus 8 to 17 • Natural methods 5 to 25 • Spermicides 5 to 25
Pros and Cons of each method • Groups/Pairs…. discuss

What are the real risks? • VTE • Cancer • Stroke
Other risks… • Which is more likely to happen? • Dying from a thrombosis from a third generation COCP • Or • Dying in a RTA
Cancers… • Is there an increase in risk of breast cancer with the COCP? • RR increased by: • 0% • 1-9% • 10-19% • 20-49% • >50%
Is there an increase in risk of breast cancer with the COCP? • RR increased by: • 25%
What is the absolute risk increase? • 0.01% • 0.1% • 0.5% • 1% • 2-10%
Absolute risk is 0.01% • Actual baseline risk <30 1:1900 30-40 1:200 • Risk increase is 12/100,000
Special considerations • Depot and osteoporosis, if young woman careful, depot causes bone mineral density to decrease at a time when it should be increasing • This is not true for implanon • Consider cerazette/other pops, >70kg rule
Frazer/Gillick competence • <13yrs not legally capable of consenting to sexual activity • 13-16 discuss and consider
Missed pills • New rules • Can miss one anywhere in pack no prob even if extend pill free interval to 8 days • See handouts
Missed pills • New rules • Can miss one anywhere in pack no prob even if extend pill free interval to 8 days • Can miss one pill anywhere in pack, no cover rqd generally unless also missed earlier in pack/in last week of previous pk • If 2 or more missed see flow chart, +use condoms until 7 consequetive pills taken +/-emergency contraception depending on where in pack.
Special considerations • Depot and osteoporosis, if young woman careful, depot causes bone mineral density to decrease at a time when it should be increasing • This is not true for implanon • Consider cerazette/other pops, >70kg rule
Enzyme inducers • Women with epilepsy • Injectable/IUD • Oral contraceptives with 50mg oestrogen • Tricycle with 4 days break • Double emergency contraceptive dosage
Migraine • Migraine with aura =absolute CI (WHO 4) • Migraine +ergots=absolute GI • Migraine +tryptan = relative CI • Migraine +1 other RF=relative CI • Migraine + No Aura +no additional stroke risk factors = OK
When should contraception be started? • IUCD within 12 days of period onset • Mirena day 1-7 or if no risk preg at other time • Depot-? • COCP?
GP activity *** swopping pills/hrt • Side effects can be oestrogenic/progestogenic • Guillain book (pill ladder) • *******Photocopy, brainstorm complaints on the pill ****** • Spots, w gain, mood swings, bleeding, migraing increased weight inc >70kg ?can have 20mcg oestrogen? • Choose an approp pill *******
C19 derivatives E.g Norethisterone Levonorgestorel More androgenic More likely to cause side effects C21 derivatives E.g Medroxyprogestogen acetate Dydrogesterone Less androgenic Progestogens
Oestrogenic Fluid retention Bloating Breast tenderness Nausea Headache Dyspepsia (take with food) Consider changing dose, changing oestrogen or changing delivery Progestogenic (In a cyclical pattern) Fluid retention Breast tenderness Mood swings Depression Acne Backache Reduce progestogen duration to 10 days per cycle, change progestogen c19/21 derivatives, delivery Side Effects
Important things to worry about with the COCP? • VTE • Cancer –breast/ovarian • Stroke • Use the BNF cautions contraindications list… 2 strikes and you’re out!
Dianette/Yasmin • Can we use for contraception? • For acne? • What are the concerns?
Cardiovascular Risk • Absolute risk of MI in non smoking age <35 very low irrespective of COCP use • Excess risk <35 approx 3/1,000,000/yr • >35 Excess risk approx 400/1,000,000/yr • 10x risk if smoke
Antibiotics and the pill • But ILL rules, (D/V still apply, and abx can induce these!)
