Emergency contraception: early access is essential.

Emergency contraceptive pill (Levonelle-1500):

  • Up to 24 hours, 95% effective
  • Up to 48 hours, 85% effective
  • Up to 72 hours, 58% effective

Levonelle-1500 is a progestogen-only oral contraceptive designed to be used for the occasional emergency when sexual intercourse has taken place without protection, or when protection has failed. It is not a substitute for regular contraception, as it is less effective and provides no protection from sexually transmitted infections.

One pack of Levonelle-1500 consists of 2 tablets, each containing 750mg levonorgestrel. Both tablets should be taken together as soon as possible (and no later than 72 hours) after unprotected intercourse. It can be used at any time during a menstrual cycle, unless menstrual bleeding is overdue. When taken within 24 hours after unprotected intercourse (UPSI) it is 95% effective, when taken within 48 hours after UPSI it is 85% effective, and when taken within 72 hours after UPSI it is 58% effective. An intrauterine device would be an alternative that could be used that is effective up to 5 days after unprotected intercourse. It can also be fitted in good faith up to five days after the earliest calculated ovulation day in the cycle in question. The method has the highest efficacy of any currently available emergency contraceptive and when efficacy is a priority, the IUD is the emergency contraception of choice.

Advice that should be given to patients who are prescribed Levonelle-1500:

  • Advise when she can expect her next period - advise her to seek immediate help if it is significantly different from her usual period, especially if the period is exceptionally short or light (i.e. possible failed treatment) or heavy or delayed more than 5 days.
  • Explain arrangements for ongoing contraceptive information/supply as necessary.
  • Explain arrangements for seeking advice if she experiences any other problems or concerns about treatment.

Circumstances that may reduce the reliability of Levonelle-1500:

  • Vomiting within 3 hours of taking the dose of hormones may result in inadequate absorption of the levonorgestrel and therefore impair the reliability.
  • Severe malabsorption syndromes (e.g. Crohn's disease) may reduce the absorption of levonorgestrel.
  • Reliability of this method of contraception might also be reduced by concurrent use of some drugs such as liver enzyme inducers.

Beyond this time it is possible to fit an Intrauterine Device (IUD) which will act as both immediate and long term contraception.

Supply of EHC can be gained from any GP, via a prescription, Family Planning Clinics and some local pharmacies in Brighton.
