“Health professionals can be ‘reasonably certain’ that a woman is not currently pregnant………..” 23/11/2016J Bowden Oct 2003 9 Always a good one for the exam…..
10
Criteria for excluding pregnancy (adapted from UK Selected Practice Recommendations for Contraceptive Use)8 Health professionals can be ‘reasonably certain’ that a woman is not currently pregnant if any one or more of the following criteria are met and there are no symptoms or signs of pregnancy: Has not had intercourse since last normal menses Has been correctly and consistently using a reliable method of contraception Is within the first 7 days of the onset of a normal menstrual period Is within 4 weeks postpartum for non-lactating women 23/11/2016J Bowden Oct 2003 10
11
Is within the first 7 days post-abortion or miscarriage Is fully or nearly fully breastfeeding, amenorrhoeic, and less than 6 months postpartum. A pregnancy test, if available, adds weight to the exclusion of pregnancy but only if ≥3 weeks since the last episode of UPSI. NB. Health professionals should also consider if a woman is at risk of becoming pregnant as a result of UPSI within the last 7 days and undertake pregnancy testing where appropriate (≥3 weeks since last UPSI). 23/11/2016J Bowden Oct 2003 11
12
Combined Oral Contraceptive (CoC). Available since 1961 in the UK. Very popular method. A safe method. Dosages have changed over the last 40 yrs. Efficacy: 0.1 per 100 women yrs (True) 0.3-4 per 100 women yrs (Typical) 23/11/2016J Bowden Oct 200312
13
COC: Main Action Positive feedback. Suspends the release of GNRH. Effectively puts the ovaries in to suspension (Asleep Zzzzz). Rule of 7! 1st 7 inhibit ovulation Remaining 14 maintain anovulation 23/11/2016J Bowden Oct 200313
14
COC: Back up action: Cervical Changes: HOSTILE. Prevents sperm entering Endometrial Changes: THIN Prevents implantation Tube Motility affected. SLOWS Slows passage of ovum 23/11/2016J Bowden Oct 200314
15
Commonly used CoCs contain ethinyloestradiol (EE) plus a progestogen. Identified by the term “generation”. Identifed by the term “phasic”. Can be 21/7 or everyday (ED). 23/11/2016J Bowden Oct 200315
16
“Generation” CoCs containing more than 50mcgs of Oestrogen are 1 st. CoCs containing less than 50mcgs plus levonorgestrel, norethisterone, cyproterone acetate or norgestimate are 2 nd. 3 rd generation CoCs contain Desogestrel or Gestodene Destogestrel and Gestodene are new progestogens. Have a higher affinity to progesterone receptors. Bind more strongly. Increase mechanisms of the CoC with a lower dose. Have fewer carbohydrate and lipid metabolic effects. 30mcgs-20mcgs most commonly used. 23/11/2016J Bowden Oct 200316
17
“Phasic” Monophasic – same dosage throughout the 21 days. Biphasic – designed to be more oestrogenic in the 1 st part of the cycle. Not commonly used in the UK. Triphasic - mimics the natural fluctuations in the normal menstrual cycle. Increases the progestogen 3 times. Quadraphasic- designed to be “more Natural” Changes in both the Oestrogen & Progestogen QLAIRA 23/11/2016J Bowden Oct 200317
18
UK Medical Eligibility Criteria: UKMEC 1 : No restriction for the use of the method. UKMEC 2: Advantages generally outweigh the risk of use of the method. UKMEC 3: Risk usually outweighs the benefit of using the method- Expert clinical judgement UKMEC 4: Unacceptable health risk if used. Please read the following URL link: 23/11/2016J Bowden Oct 200318

Ca colorectal: Reversible immediately. Return of Fertility. Less PID (?). Less risk of Toxic Shock. Woman controlled. Not related to sexual intercourse. 23/11/2016J Bowden Oct 200326
27
Combined Patches: EVRA 3 patches. 1 worn for 7 days for 3 weeks. 1 patch free week. Similar to CoC. Considered ideal for those with pill taking difficulties. per 24 hours. 23/11/2016J Bowden Oct 2003 27 Usually 33.9 μg EE and 203 μg norelgestromin
28
Vaginal Rings: NuvaRing ™. Combined method. Flexible, transparent ring. 3 weeks of ring use. 1 ring free week. Similar to CoC. Not ideal immediately PN 23/11/2016J Bowden Oct 2003 28 EE and etonogestrel at daily rates of 15 μg and 120 μg
29
Which Pill? CoC chosen should: Provide effect contraceptive control. Produce acceptable cycle. Is associated with the fewest side effects. The lowest dose first. 23/11/2016J Bowden Oct 200329

31
Progestogen Only Pill (PoP): Effective oral alternative to the CoC when exogenous oestrogen is not wanted/advised. Single dose of Progestogen. Efficacy 0.3 –4 per 100 women yrs. Efficacy increases with age. No evidence re heavier women and decreased efficacy No evidence that change brands improves bleeding 23/11/2016J Bowden Oct 200331 NEVER THE “MINI PILL”
32
Mode of Action Development of hostile mucus. Reducing receptivity of the Endometrium. Reducing tube motility. Reducing Ovulation. 23/11/2016J Bowden Oct 200332

36
Cerazette: Desogestrel-only Potential benefit over tradition POP. 75 mcgs of Desogestrel. Works in the same way as other POPs EXCEPT it effects ovulation and inhibits it in 97% of women. 12 hour missed window Beneficial with dysmenorrhea Rewrites the textbooks as it is has similar benefits as the COC in relation to action and missed pill routine as the coc (without the 7/7 PFI) with the benefits of the POP. BUT efficacy not significantly different to traditional POPs 23/11/2016J Bowden Oct 200336
37
POP & Enzyme –inducing Drugs 23/11/2016J Bowden Oct 2003 37 Advised to switch to the progestogen-only injectable or intrauterine contraception. For short durations of enzyme-inducing treatment (<2 months) women can continue the POP providing they use additional precautions during treatment and for 28 days afterwards. Women wishing to start the POP after stopping enzyme- inducing drugs should be advised to use condoms until 28 days after the last dose of enzyme-inducing drug.
38

39
Mode of Action of POEC Not fully understood. Not an abortion. Inhibit/delay ovulation. Affects endometrium. Affects ova transportation. Affects sperm transportation. 23/11/2016J Bowden Oct 200339
40
Advantages/disadvantages Prevents pregnancy. No absolute contraindications. Ease of availability. Efficacy hard to establish. Mode of action difficult to explain. Nausea/vomiting main side effect. Alteration to next menses. 23/11/2016J Bowden Oct 200340
41
ellaOne™: Single dose 30mgs Ulipristal acetate: synthetic progesterone modulator. Binds to progesterone receptors. Primary action delays/inhibits ovulation PLUS possible alteration to the endometrium. Licensed up to 120 hrs. Side effects similar to Levonelle. Prescription only Affects progestogen within contracepton 23/11/2016J Bowden Oct 200341
42
Clinical Management Careful history from client. Liver enzyme inducing drugs* Multiple episodes?
