Emergency hormonal contraception (EHC) helps prevent pregnancy after unprotected sex or contraceptive failure. It is commonly known as the “morning-after pill” and should be taken as soon as possible for the best results.

Types of Emergency Hormonal Contraception

There are two main types of emergency contraceptive pills available in the UK:

  1. Levonorgestrel (Levonelle) – This pill contains levonorgestrel, a synthetic hormone similar to progesterone. It should be taken within 72 hours (3 days) of unprotected sex. It is most effective when taken earlier.
  2. Ulipristal Acetate (ellaOne) – This pill contains ulipristal acetate and can be taken within 120 hours (5 days). It works by delaying ovulation and is considered more effective than Levonorgestrel, especially if ovulation is near.

How It Works

Both types of emergency hormonal contraception work by:

  • Preventing or delaying ovulation (release of an egg).

  • Making it harder for sperm to reach the egg.

Emergency contraception does not cause an abortion and will not work if pregnancy has already started.

Effectiveness

The sooner you take emergency contraception, the more effective it will be.

  • Levonorgestrel is around 95% effective if taken within 24 hours, but effectiveness decreases over time.

  • ellaOne remains highly effective for up to five days after unprotected sex.

Where to Get Emergency Contraception

Emergency hormonal contraception is available at:

  • Pharmacies (including at “Parklands”).
  • GP surgeries.
  • Sexual health clinics.
  • Some NHS walk-in centres.

Women under 25 may be able to get it for free from certain NHS services.

Side Effects

Most women tolerate emergency contraception well, but some may experience:

  • Nausea or vomiting (if you vomit within 3 hours of taking the pill, another dose may be needed).

  • Irregular bleeding or changes in the next period.

  • Headaches, dizziness, or mild stomach pain.

Who Can Take It?

Most women can use emergency contraception, but it may not be suitable for those with certain medical conditions or taking specific medications. If in doubt, consult a pharmacist or GP.

Alternative Options

The copper intrauterine device (IUD) is another emergency contraception method. It can be fitted within 5 days of unprotected sex and is over 99% effective in preventing pregnancy. Unlike the pill, it provides ongoing contraception.

Final Thoughts

Emergency contraception is a safe and effective way to prevent pregnancy after unprotected sex. If you need advice, visit a healthcare professional or speak to a pharmacist at “Parklands” for guidance.
