YazQlairaMissed PillsFlexible Pill taking Regimes

Page 4: Contraception Update

COCP: Yaz20mcg EE + 3 mg DrospirenoneNew regime 24/28

Take active Pills for 24 days then 4 day placebos Shorter PFI is more effective

Licensed USA Contraception, acne and PMDD

Benefits Less Dysfunctional Bleeding Less PMS Less Blood loss by 50-60%

Page 5: Contraception Update

COCP: YazInitial efficacy data from USA

3-5 year follow up of new starters or switchers

Prospective recruitment 434 unplanned pregnancies

By March 2008 Pearl Index for 24day regime 0.94 Pearl Index for 21 day regime DRSP/EE 1.5 Pearl Index for 21day regime other COCP 2.22

COCP: QlairaOestradiol Valerate+ DienogestBenefits

More ‘natural’,effective and safe Cycle control like 20mcg LNG Pill Little effect on glucose, lipids, BP, coagulation

factors

Disadvantages New so limited data on VTE / CHD risk etc Need to take all 28 Pills in correct order (EE: Prog) Different Missed Pills rules

Qlaira regime26/2

Maintain stable E2 levels, optimise cycle control, inhibit ovulation

Missed Pills

MHRA decided not acceptable to have so much conflicting information

New set of missed Pill rulesNot dependant on doseNB separate rules for

QLAIRA-Quadraphasic Pill –use SPCCerazetteProgestogen only Pills

Page 13: Contraception Update

Missed Pill RulesCEU- May13th 20111 missed Pill ( >24 hrs late or PFI lengthened by 1 day)

Take Pill as soon as rememberContinue rest of pack No additional contraception neededHave 7 day break as normal

Page 14: Contraception Update

Missed Pill RulesCEU- May13th 20112 missed Pills ( or PFI lengthened by 2 days)

Take Pill as soon as rememberContinue rest of pack Use additional contraception for 7 daysEC if 2 pills are in first week of packetNo break if less than 7 Pills left in packet

FLEXIBLE PILL TAKING REGIMES

Page 16: Contraception Update

COCP :Flexible regimeTricycling

3 packets back to back with no break 63 continuous days

Reduce Pill free interval to 3-4 daysReduce bleedingMinimise risk of lengthening break

‘Break at bleed’Take Pills continuously until break through

bleed occursBreak for 4 -7 days then restart

Page 17: Contraception Update

When to use alternative regime?PFI side effects

Heavy/painful bleed in PFI Headaches/ migraines in PFI PMS

Cyclical symptomsEndometriosisPrevious Pill failureWomen’s Choice/ convenience

Alternative ways of delivering combined EE & Progestogen

Page 19: Contraception Update

Nuva RingVaginal Ring

15µg/day EE and 120µg/day Etonogestrel Flexible transparent ring,4mm thick x 54mm diameter Latex free

Use 1 Ring for 3 weeks then 7 day break Can be used with tampons and during SI

Pharmacology Avoids first pass metabolism& GI interference with

absorption Systemic EE is 50% of that of 30µg EE COCP

Efficacy Pearl Index 0.64 ( perfect use) Comparable to COCP

Irregular Bleeding Patterns-Management OptionsPre-insertion/fitting/injection CounsellingProgestogen Injection

Shorten interval to 8/52 until amenorrhoeicIUS / Nexplanon

Change earlier is bleeding starts in final year of useDrug treatments

COCP cyclically for 2-3 months NSAIDs/ Mefanamic Acid( little evidence) Doxycycline (little evidence) NET 5mg tds for 3 weeks for 2-3 cycles

Problems Recurrence of bleeding when discontinues treatment

Page 29: Contraception Update

Quick start regimes

Page 30: Contraception Update

Quick startIf we can be reasonably sure that a woman is

not pregnant or at risk of a pregnancy from recent UPSI, contraception can be started immediately.

Use may be out of licenceIf method of choice is not available use bridging

method- COCP, POP or Injectable ProgestogenIUCD can be used if meet EC criteriaIUS insertion should be delayed until

pregnancy excluded

Page 31: Contraception Update

Quick startIf pregnancy cannot be excluded (eg after EC

administration) &women will not abstain until pregnancy is excluded or is keen to start method immediately COCP, POP, Nexplanon can be started .

Injectable progestogen should only be used if other options are not appropriate or acceptable

Follow-up with pregnancy test after 3 weeksUse may be out of licence

Page 32: Contraception Update

Quick startStarting hormonal contraception after POEC

(eg Levonelle)Advise condom use or abstainance for

7 days for COCP, Nexplanon, Injectable Progestogen

2days for POP9days for Qlaira

Page 33: Contraception Update

Quick startStarting hormonal contraception after Ullipristal

(EllaOne)Advise condom use or abstainance for an extra

week

14 days for COCP, Nexplanon, Injectable Progestogen

9 days for POP16 days for Qlaira

Page 34: Contraception Update

Pregnancy after quickstartIf pregnancy is diagnosed after quick starting

contraceptionStop or remove method

Do not remove IU contraceptives after 12 weeks gestation if threads not visible

Page 35: Contraception Update

Drug interactions

Page 36: Contraception Update

Drug interactions- AntibioticsCEU no longer advises that additional

precautions are required when using CHC with non-enzyme inducing antibiotics

EVIDENCE in line with World Health OrganisationUS Medical eligibility Criteria for Contraceptive

Use

Page 37: Contraception Update

Drug interactions- AntibioticsEVIDENCE

Several studies show no decrease in EE levels with antibiotic use

Small non randomised trials no effect on pharmacokinectocs of EE/ progestogen when used with tetracyclinc/amoxicillin/doxycycline

Small non randomised trials failed to show that ampicillin has any effect on gonadotrophin conc or progesterone levels in women using >30µg COCP

Small RCTs showed Ofloxacin & Ciprofloxacin may not affect COC efficacy ( no ovulation)

Page 38: Contraception Update

Drug interactions-Enzyme inducersRifampicin-like drugs are enzyme inducers and are

the only antibiotics that have been shown to reduce EE levels

Methods unaffected IUCDIUSInjectable progestogen

Page 39: Contraception Update

Drug interactions-Enzyme inducersCombined Pill

Change method(or long term 2 x50µg COC)Patch/ Ring

Change method(2Patches/ 2Rings not recommended)POP/Nexplanon

Change methodPOEC- Levonelle

Use 3mg LNG asapUllipristal Acetate- EllaOne

Ella One contraindicatedUse IUCD if enzyme-inducers in last 28days

Page 40: Contraception Update

Drug interactions- no longer includedWarfarin

Increase or decrease of anticoagulant effect with hormonal contraception

Lack of consistant evidence therefore no longer included

GriseofulvinNot a clinically important enzyme inducer

LanzoprazoleNo longer listed as an enzyme inducer

Page 41: Contraception Update

Drug interactions- LamotrigineCHC not recommended in women on

Lamotrigine monotherapy ( UKMEC3)Risk of reduced seizure controlPotential for toxicity in the CHC free intervalProgestogens

Levels of some progestogens may be reducedMay increase levels of LamotrigineNeed more evidence (still UKMEC1 for PO

methods)
