Long-acting reversible contraception Clinical guideline (NICE CG30 October 2005, updated July 2019)

  • Long-acting reversible contraceptive (LARC), intrauterine devices (IUD), intrauterine system (IUS), injectable contraceptives and implants are more cost effective than the combined oral contraceptive pill. They are also the most reliable method of contraception.

Scenario: Combined oral contraceptive (NICE CKS updated September 2022)

Drug Interactions with Hormonal Contraception (Faculty of Sexual and Reproductive Healthcare, updated May 2022)

  • No additional contraceptive precaution is required during use of an antibiotic unless the antibiotic is an enzyme inducer or the antibiotic (and/or the illness being treated) causes vomiting or diarrhoea.
  • Enzyme-inducing drugs could reduce contraceptive effectiveness of all combined hormonal contraception, all progestogen-only pills, the etonogestrel implant and oral emergency contraception. Individuals using an enzyme-inducing drug should be offered a reliable contraceptive method that is unaffected by the enzyme inducer. Intrauterine contraception and depot medroxyprogesterone acetate (either intramuscular or subcutaneous) are appropriate options.
  • Individuals using an enzyme-inducing drug who require emergency contraception should be advised that effectiveness of oral emergency contraception could be reduced. They should be offered a copper IUD if indicated. If a copper IUD is unacceptable, unsuitable or unavailable, a double dose (3mg) of levonorgestrel oral emergency contraception or a single dose (30mg) of ulipristal acetate oral emergency contraception can be offered if indicated, with advice that effectiveness is unknown.
  • Short-term users (<2 months) of an enzyme inducer may wish to consider continuing their existing method of contraception and using condoms reliably in addition during use of the enzyme inducer and for 28 days after it has been stopped (this is not recommended during use of a teratogen).

Decision-making Algorithm for Oral Emergency Contraception (Faculty of Sexual and Reproductive Healthcare, March 2017, updated December 2020)

  • Patients who have a BMI >26 or are greater than 70kg may require more than the standard 1.5mg dose of levonorgestrel. Consider double dose (3mg) or CI-IUD or ulipristal. 

Combined Hormonal Contraception Clinical guideline (Faculty of Sexual and Reproductive Healthcare, January 2019, updated November 2020)

  • Women who have had bariatric surgery should be advised that the effectiveness of COC could be reduced and should consider a non-oral contraception.

Progestogen-only Pills (Faculty of Sexual and Reproductive Healthcare August 2022, updated November 2022)

  • Women who have had bariatric surgery should be advised that there is insufficient evidence to inform whether contraceptive effectiveness of POPs is affected by bariatric surgery and may therefore wish to consider non-oral contraception.

If vomiting occurs within 3 hours of the tablet intake, another tablet should be taken.
Contraception, progestogen-only
Progestogen
Desogestrel75mcg tablet: £5.25 (84)Tablets must be taken every day, continuously, at about the same time so that the interval between two tablets always is 24 hours.

If the user is less than 12 hours late in taking any tablet, the missed tablet should be taken as soon as it is remembered and the next tablet should be taken at the usual time. If she is more than 12 hours late, she should use an additional method of contraception for the next 7 days.
Norethisterone as Noriday®350mcg tablet: £2.10 (84)Take one pill every day without a break in medication.

If a pill is missed within 3 hours of the correct dosage time then the missed pill should be taken as soon as possible; this will ensure that contraceptive protection is maintained. If a pill is taken 3 or more hours late it is recommended that the woman takes the last missed pill as soon as possible and then continues to take the rest of the pills in the normal manner. However, to provide continued contraceptive protection it is recommended that an alternative method of contraception, such as a condom, is used for the next 7 days.
Levonorgestrel as Norgeston®30mcg tablet: £0.92 (35)
Drospirenone as Slynd®4mg tablet: £14.70 (84)One active tablet once daily for 24 days, followed by one inactive tablet once daily for 4 days, to be started on day 1 of cycle with first active tablet (withdrawal bleeding may occur during the 4-day interval of inactive tablets); subsequent courses repeated without interval.

If administration delayed for 24 hours or more it should be regarded as a ‘missed pill' and contraceptive protection may be reduced. Use of a barrier method such as a condom should be considered for the next 7 days. The missed tablet should be taken as soon as it is remembered, even if this means taking two tablets at the same time. She then continues to take tablets at her usual time.

If tablets were missed in the first week after initiation and intercourse took place in the week before the tablets were missed, the possibility of a pregnancy should be considered.

If tablets were missed in the third week of pill taking, the risk of reduced reliability is imminent because of the forthcoming 4-day hormone-free interval. However, by adjusting the tablet-intake schedule, reduced contraceptive protection can still be prevented. The user should take the last missed tablet as soon as she remembers, even if this means taking two tablets at the same time. She then continues to take the active tablets at her usual time. The user is advised not to take the placebo pills and continue straight on to the next active blister pack.

Missed (green) placebo tablets can be disregarded. However, they should be discarded to avoid unintentionally prolonging the interval between active tablet taking.

If vomiting or diarrhea occurs within 3-4 hours after tablet taking, a new (replacement) tablet should be taken as soon as possible. The new tablet should be taken within 24 hours of the usual time of tablet-taking if possible. If more than 24 hours elapse, need to follow advice concerning missed tablets.
