MISSED PILL RULES
Missed Pills
Multiple sources of advice
FSRH guidance
SPC- leaflet in box of Pills
FPA leaflet
BNF
ALL DIFFERENT
Conflicting advice leads to confusion
Inaccurate & inconsistent Pill taking
Missed Pills
MHRA decided not acceptable to have so much
conflicting information
New set of missed Pill rules
Not dependant on dose
NB separate rules for
QLAIRA-Quadraphasic Pill –use SPC
Cerazette
Progestogen only Pills
Missed Pill Rules
CEU- May13th 2011
1 missed Pill
( >24 hrs late or PFI lengthened by 1 day)
Take Pill as soon as remember
Continue rest of pack
No additional contraception needed
Have 7 day break as normal
Missed Pill Rules
CEU- May13th 2011
2 missed Pills ( or PFI lengthened by 2 days)
Take Pill as soon as remember
Continue rest of pack
Use additional contraception for 7 days
EC if 2 pills are in first week of packet
No break if less than 7 Pills left in packet
FLEXIBLE PILL TAKING REGIMES
COCP :Flexible regime
Tricycling
3 packets back to back with no break
63 continuous days
Reduce Pill free interval to 3-4 days
Reduce bleeding
Minimise risk of lengthening break
‘Break at bleed’
Take Pills continuously until break through bleed occurs
Break for 4 -7 days then restart
When to use alternative regime?
PFI side effects
Heavy/painful bleed in PFI
Headaches/ migraines in PFI
PMS
Cyclical symptoms
Endometriosis
Previous Pill failure
Women’s Choice/ convenience
Alternative ways of delivering combined EE & Progestogen
Nuva Ring
Vaginal 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
Nuva Ring
Compliance
>85% of cycles compliant in trials
Acceptibility
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)
Failure rates
Management of bleeding problems
Nexplanon

Etonogestrel 68mg released over 3 years
Most effective method available for women
Change insertion device
New technique
Reduced chance of leaving device in inserter
Change component

Pregnancies
>50% linked with non-insertion
25% with liver enzyme inducers (carbemazepine)
Pregnancy rate

Drug 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
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)
