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

conflicting information

 Break for 4 -7 days then restart
When to use alternative regime?
 PFI side effects




Pearl Index 0.64 ( perfect use)
Comparable to COCP
Nuva Ring
 Compliance

>85% of cycles compliant in trials




Low incidence of Break through bleeding
Better than COCP for cycle control
>90% trial subjects found easy to insert and remove
 Safety

Same metabolic and coagulation effects as most combined
methods
 Storage

2-8°C before dispensing to patient
 Cost

£27 for 3 rings ( £9 per month)


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
Quick start regimes
Quick start
 If 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 licence
 If method of choice is not available use bridging
method- COCP, POP or Injectable Progestogen
 IUCD can be used if meet EC criteria
 IUS insertion should be delayed until pregnancy
excluded
Quick start
 If 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 weeks
 Use may be out of licence
Quick start
 Starting hormonal contraception after POEC
(eg Levonelle)
 Advise condom use or abstainance for
 7 days for COCP, Nexplanon, Injectable Progestogen
 2days for POP
 9days for Qlaira
Quick start
 Starting hormonal contraception after Ullipristal
(EllaOne)
 Advise condom use or abstainance for an extra week
 14 days for COCP, Nexplanon, Injectable Progestogen
 9 days for POP
 16 days for Qlaira
Pregnancy after quickstart
 If pregnancy is diagnosed after quick starting
contraception
 Stop or remove method
 Do not remove IU contraceptives
 after 12 weeks gestation
 if threads not visible
Drug interactions
Drug interactions- Antibiotics
 CEU no longer advises that additional precautions are
required when using CHC with non-enzyme inducing
antibiotics
 EVIDENCE in line with
 World Health Organisation
 US Medical eligibility Criteria for Contraceptive Use
Drug interactions- Antibiotics
 EVIDENCE
 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)
Drug interactions-Enzyme inducers
 Rifampicin-like drugs are enzyme inducers and are the only
antibiotics that have been shown to reduce EE levels
 Methods unaffected
 IUCD
 IUS
 Injectable progestogen
Drug interactions-Enzyme inducers
 Combined Pill
 Change method(or long term 2 x50µg COC)
 Patch/ Ring
 Change method(2Patches/ 2Rings not recommended)
 POP/Nexplanon
 Change method
 POEC- Levonelle
 Use 3mg LNG asap
 Ullipristal Acetate- EllaOne
 Ella One contraindicated
 Use IUCD if enzyme-inducers in last 28days
Drug interactions- no longer included
 Warfarin
 Increase or decrease of anticoagulant effect with
hormonal contraception
 Lack of consistant evidence therefore no longer
included
 Griseofulvin
 Not a clinically important enzyme inducer
 Lanzoprazole
 No longer listed as an enzyme inducer
Drug interactions- Lamotrigine
 CHC not recommended in women on Lamotrigine
monotherapy ( UKMEC3)
 Risk of reduced seizure control
 Potential for toxicity in the CHC free interval
 Progestogens
 Levels of some progestogens may be reduced
 May increase levels of Lamotrigine
 Need more evidence (still UKMEC1 for PO methods)
