Combined oral contraceptive pill - different options for how to take it

A

‘Tailored’ regimes should now be discussed with women. This is because there is no medical benefit from having a withdrawal bleed. Options include never having a pill-free interval or ‘tricycling’ - taking three 21 day packs back-to-back before having a 4 or 7 day break

Q

Combined oral contraceptive pill & Concurrent antibiotic use

concurrent use of antibiotics may interfere with the enterohepatic circulation of oestrogen and thus make the combined oral contraceptive pill ineffective - ‘extra-precautions’ were advised for the duration of antibiotic treatment and for 7 days afterwards

A

false
no such precautions are taken in the US or the majority of mainland Europe
in 2011 the Faculty of Sexual & Reproductive Healthcare produced new guidelines abandoning this approach. The latest edition of the BNF has been updated in line with this guidance

52
Q

Implantable contraceptive Adverse effects

A

irregular/heavy bleeding is the main problem

‘progestogen effects’: headache, nausea, breast pain

53
Q

Implantable contraceptive irregular/heavy bleeding management

A

this is sometimes managed using a co-prescription of the combined oral contraceptive pill. It should be remembered to do a speculum exam/STI check if the bleeding continues

54
Q

Implantable contraceptive interactions

A

enzyme-inducing drugs such as certain antiepileptic and rifampicin may reduce the efficacy of Nexplanon
the FSRH advises that women should be advised to switch to a method unaffected by enzyme-inducing drugs or to use additional contraception until 28 days after stopping the treatment

55
Q

Implantable contraceptive UKMEC 3

A

ischaemic heart disease/stroke (for continuation, if initiation then UKMEC 2), unexplained, suspicious vaginal bleeding, past breast cancer, severe liver cirrhosis, liver cancer

56
Q

Implantable contraceptive UKMEC 4

A

current breast cancer

57
Q

Injectable contraceptive example

A

Depo Provera is the main injectable contraceptive used in the UK

Noristerat, the other injectable contraceptive licensed in the UK, is rarely used in clinical practice. It is given every 8 weeks

58
Q

Injectable contraceptive contains

A

medroxyprogesterone acetate 150mg

59
Q

Injectable contraceptive given via

A

intramuscular injection every 12 weeks. It can however be given up to 14 weeks after the last dose without the need for extra precautions

the BNF gives different advice, stating a pregnancy test should be done if the interval is greater than 12 weeks and 5 days - this is however not commonly adhered to in the family planning community

60
Q

Injectable contraceptive acts by

A

The main method of action is by inhibiting ovulation. Secondary effects include cervical mucus thickening and endometrial thinning.

61
Q

Injectable contraceptive disadvantafes

A

Disadvantages include the fact that the injection cannot be reversed once given. There is also a potential delayed return to fertility (maybe up to 12 months)

62
Q

Injectable contraceptive adverse effects

A

irregular bleeding
weight gain
may potentially increased risk of osteoporosis: should only be used in adolescents if no other method of contraception is suitable
not quickly reversible and fertility may return after a varying time

63
Q

Injectable contraceptive contraindications

A

breast cancer: current breast cancer is UKMEC 4, past breast cancer is UKMEC 3

64
Q

Intrauterine contraceptive devices comprise

A

both conventional copper intrauterine devices (IUDs) and levonorgestrel-releasing intrauterine systems (IUS, Mirena®).

65
Q

The IUS is also used in the management of menorrhagia

A

true

66
Q

Intrauterine contraceptive devices Effectiveness

A

both the IUD and IUS are more than 99% effective

67
Q

Intrauterine contraceptive devices Mode of action IUD

A

primary mode of action is prevention of fertilisation by causing decreased sperm motility and survival (possibly an effect of copper ions)

68
Q

Intrauterine contraceptive devices Mode of action IUS

A

levonorgestrel prevents endometrial proliferation and causes cervical mucous thickening

69
Q

Intrauterine contraceptive devices counselling IUD

A

can be relied upon immediately following insertion
the majority of IUDs with copper on the stem only are effective for 5 years, whereas some of the IUDs that have copper on the stem and the arms of the T may be effective for up to 10 years

70
Q

Intrauterine contraceptive devices counselling IUS

A

can be relied upon after 7 days
the most common IUS (i.e. Mirena® - levonorgestrel 20 mcg/24 hrs) is effective for 5 years
if used as endometrial protection for women taking oestrogen-only hormone replacement therapy they are only licensed for 4 years

71
Q

Intrauterine contraceptive devices potential problems periods:

A

IUDs make periods heavier, longer and more painful

the IUS is associated with initial frequent uterine bleeding and spotting.

Later women typically have intermittent light menses with less dysmenorrhoea and some women become amenorrhoeic

72
Q

Intrauterine contraceptive devices uterine perforation

A

up to 2 per 1000 insertions and higher in breastfeeding women

73
Q

Intrauterine contraceptive devices - ectopic pregnancy rx

A

the proportion of pregnancies that are ectopic is increased but the absolute number of ectopic pregnancies is reduced, compared to a woman not using contraception

74
Q

Intrauterine contraceptive devices - infection rx

A

infection: there is a small increased risk of pelvic inflammatory disease in the first 20 days after insertion but after this period the risk returns to that of a standard population

75
Q

Intrauterine contraceptive devices expulsion

A

expulsion: risk is around 1 in 20, and is most likely to occur in the first 3 months

76
Q

Describe new IUS systems

A

The Jaydess® IUS is licensed for 3 years. It has a smaller frame, narrower inserter tube and less levonorgestrel (LNG) than the Mirena® coil (13.5 mg compared to 52 mg). This results in lower serum levels of LNG.

The Kyleena® IUS has 19.5mg LNG and is also smaller than the Mirena® but is licensed for 5 years. It also results in lower serum levels of LNG. The rate of amenorrhoea is less with Kyleena® compared to Mirena®.

77
Q

The major clinical indicators of fertility are

A

changes in the cervical mucous
changes in the cervix
changes in basal body temperature

78
Q

After giving birth women require contraception after

A

day 21

79
Q

The intrauterine device or intrauterine system can be inserted within ? hours of childbirth or after ? weeks.

A

The intrauterine device or intrauterine system can be inserted within 48 hours of childbirth or after 4 weeks.

80
Q

Post-partum contraception - POP

A

the FSRH advise ‘postpartum women (breastfeeding and non-breastfeeding) can start the POP at any time postpartum.’

after day 21 additional contraception should be used for the first 2 days

a small amount of progestogen enters breast milk but this is not harmful to the infant

81
Q

Post-partum contraception - COC

A

absolutely contraindicated - UKMEC 4 - if breast feeding < 6 weeks post-partum
UKMEC 2 - if breast feeding 6 weeks - 6 months postpartum*
the COC may reduce breast milk production in lactating mothers
may be started from day 21 - this will provide immediate contraception
after day 21 additional contraception should be used for the first 7 days

82
Q

Lactational amenorrhoea method (LAM) & POP

A

is 98% effective providing the woman is fully breast-feeding (no supplementary feeds), amenorrhoeic and < 6 months post-partum

83
Q

An inter-pregnancy interval of less than 12 months between childbirth and conceiving again is associated with

A

an increased risk of preterm birth, low birthweight and small for gestational age babies.

84
Q

There are now two methods of emergency hormonal contraception

A

levonorgestrel and ulipristal, a progesterone receptor modulator.

85
Q

Levonorgestrel

mode of action

A

not fully understood - acts both to stop ovulation and inhibit implantation

86
Q

Levonorgestrel - how should this be taken?

A

should be taken as soon as possible - efficacy decreases with time
must be taken within 72 hours of unprotected sexual intercourse (UPSI)*

87
Q

Levonorgestrel - dose?

A

single dose of levonorgestrel 1.5mg (a progesterone)

the dose should be doubled for those with a BMI >26 or weight over 70kg

88
Q

Levonorgestrel - efficacy?

84% effective is used within 72 hours of UPSI

89
Q

levonorgestrel is safe and well-tolerated.

A

true

90
Q

Levonorgestrel side effects/problems?

A

Disturbance of the current menstrual cycle is seen in a significant minority of women. Vomiting occurs in around 1%
if vomiting occurs within 3 hours then the dose should be repeated
can be used more than once in a menstrual cycle if clinically indicated

91
Q

hormonal contraception can be started immediately after using levornogestrel (Levonelle) for emergency contraception

A

true

92
Q

Ulipristal - mode of action

A

a selective progesterone receptor modulator currently marketed as EllaOne. The primary mode of action is thought to be inhibition of ovulation

93
Q

Ulipristal - dose

A

30mg oral dose taken as soon as possible, no later than 120 hours after intercourse

94
Q

Ulipristal concomitant use with levonorgestrel is not recommended

A

true

95
Q

Ulipristal may reduce the effectiveness of hormonal contraception.

A

true

96
Q

Ulipristal & other contraceptive methods

A

Contraception with the pill, patch or ring should be started, or restarted, 5 days after having ulipristal. Barrier methods should be used during this period

97
Q

Breastfeeding & emergency contrception

A

breastfeeding should be delayed for one week after taking ulipristal. There are no such restrictions on the use of levonorgestrel

98
Q

Ulipristal helps asthma

A

false

caution should be exercised in patients with severe asthma

99
Q

Ulipristal repeated dosing within the same menstrual cycle not recommended

A

false
repeated dosing within the same menstrual cycle was previously not recommended - however, this has now changed and ulipristal can be used more than once in the same cycle

100
Q

IUD as emergency contraception works by

A

may inhibit fertilisation or implantation

101
Q

IUD as emergency contraception time windoes

A

Intrauterine device (IUD)
must be inserted within 5 days of UPSI, or
if a women presents after more than 5 days then an IUD may be fitted up to 5 days after the likely ovulation date

A

false

prophylactic antibiotics may be given if the patient is considered to be at high-risk of sexually transmitted infection

103
Q

IUD as emergency contraception may be left in-situ to provide long-term contraception, but if client wishes to have it removed?

A

If the client wishes for the IUD to be removed it should be at least kept in until the next period

104
Q

IUD as emergency contraception efficacy

A

is 99% effective regardless of where it is used in the cycle

105
Q

There are a number of factors to consider for women with epilepsy:

A

the effect of the contraceptive on the effectiveness of the anti-epileptic medication
the effect of the anti-epileptic on the effectiveness of the contraceptive
the potential teratogenic effects of the anti-epileptic if the woman becomes pregnant

106

Whilst fertility has usually significantly declined by the age of 40 years women still require effective contraception until the menopause.

A

true

110
Q

Which method of contraception is UKMEC 2 for older women

A

combined oral contraceptive pill (UKMEC2 for women >= 40 years) and Depo-Provera (UKMEC2 for women > 45 years).

111
Q

Contraception for women aged > 40 years COCP

A

COCP use in the perimenopausal period may help to maintain bone mineral density
COCP use may help reduce menopausal symptoms
a pill containing < 30 µg ethinylestradiol may be more suitable for women > 40 years

112
Q

Contraception for women aged > 40 years Depo-Provera

A

women should be advised there may be a delay in the return of fertility of up to 1 year for women > 40 years
use is associated with a small loss in bone mineral density which is usually recovered after discontinuation

113
Q

hormone replacement therapy (HRT) cannot be relied upon for contraception

A

true
The FSRH advises that the POP may be be used with in conjunction with HRT as long as the HRT has a progestogen component (i.e. the POP cannot be relied upon to ‘protect’ the endometrium). In contract the IUS is licensed to provide the progestogen component of HRT.

114
Q

Stopping contraception

Non-hormonal (e.g. IUD, condoms, natural family planning)

A

Women < 50 years - Stop contraception after 2 years of amenorrhoea
Women >= 50 years - Stop contraception after 1 year of amenorrhoea

115
Q

Stopping contraception COCP

A

Women < 50 years -Can be continued to 50 years

Women >= 50 years - Switch to non-hormonal or progestogen-only method

116
Q

Stopping contraception Depo-Provera

A

Women < 50 years- Can be continued to 50 years
Women >= 50 years- Switch to either a non-hormonal method and stop after 2 years of amenorrhoea OR switch to a progestogen-only method and follow advice below

117
Q

Stopping contraception Implant, POP, IUS

A

Women < 50 years - Can be continued beyond 50 years
Women >= 50 years - Continue

If amenorrhoeic check FSH and stop after 1 year if FSH >= 30u/l or stop at 55 years

If not amenorrhoeic consider investigating abnormal bleeding pattern

118
Q

children under the age of 13 years are considered unable to consent for sexual intercourse and hence consultations regarding this age group should automatically trigger child protection measures

A

true

119
Q

the age of consent for sexual activity in the UK is 16 years. Practitioners may however provide advice and contraception if they feel that the young person is ‘competent’. This is usually assessed using the Fraser guidelines

A

true

120
Q

The Fraser Guidelines state that all the following requirements should be fulfilled:

A

the young person understands the professional’s advice
the young person cannot be persuaded to inform their parents
the young person is likely to begin, or to continue having, sexual intercourse with or without contraceptive treatment
unless the young person receives contraceptive treatment, their physical or mental health, or both, are likely to suffer
the young person’s best interests require them to receive contraceptive advice or treatment with or without parental consent

121
Q

Sexual Transmitted Infections (STIs)

young people

A

should be advised to have STI tests 2 and 12 weeks after an incident of unprotected sexual intercourse (UPSI)

122
Q

young people Choice of contraceptive

A

clearly long-acting reversible contraceptive methods (LARCs) have advantages in young people as this age group may often be less reliable in remembering to take medication
however, there are some concerns about the effect of progesterone-only injections (Depo-provera) on bone mineral density and the UKMEC category of the IUS and IUD is 2 for women under the age of 20 years, meaning they may not be the best choice
the progesterone-only implant (Nexplanon) is therefore the LARC of choice is young people

123
Q

A transgender individual is someone whose gender identity is not congruent with the sex they were assigned at birth.

A

true

124
Q

In terms of regular contraception in patients assigned female at birth and with a uterus:

A

Testosterone therapy does not provide protection against pregnancy and if the patient becomes pregnant, testosterone therapy is contraindicated as can have teratogenic effects.
Regimes containing oestrogen are not recommended in patients undergoing testosterone therapy as can antagonize the effect of testosterone therapy.
Progesterone only contraceptives are not considered to have any detrimental effect on testosterone therapy and the intrauterine system and injections may also suspend menstruation.
Non-hormonal intrauterine devices do not interact with hormonal regimes but can exacerbate menstrual bleeding, which may be unacceptable to patients.

125
Q

In patients assigned male at birth what may reduce sperm

A

oestradiol, gonadotrophin-releasing hormone analogs, finasteride or cyproterone acetate, there may be a reduction or cessation of sperm production, however, the variability of the effects of such therapy is such that they cannot be relied upon as a method of contraception. Condoms should be recommended in those patients assigned male at birth engaging in vaginal sex wishing to avoid the risk of pregnancy.

126
Q

In patients assigned female at birth where there is a risk of pregnancy following unprotected vaginal intercourse and the patient would like to avoid an unplanned pregnancy, emergency contraception may be required. Either of the available oral emergency contraceptive options may be considered as it is believed that neither oral formulation interacts with testosterone therapy. In addition, the non-hormonal intrauterine device may be considered, however, as mentioned, this may have unacceptable side effects in some patients.

A

True

127
Q

Clearly, individuals who have undergone a hysterectomy and/or bilateral oophorectomy are no longer at risk of pregnancy. Likewise, the risk of impregnating would not be a consideration in patients that have undergone a bilateral orchiectomy. For patients seeking permanent contraception, a fallopian tube occlusion or a vasectomy may be the most appropriate solution and neither would be affected by hormonal therapy.

A

True
