EllaOne is a type of emergency hormonal contraception, which we frequently call the morning after pill. If taken correctly EllaOne can be used to prevent unplanned pregnancy after unprotected sex or condom failure.

How does EllaOne work?

This medicine works by delaying or preventing ovulation. Ovulation is when the ovary releases an egg for a sperm to fertilise. It is hard to predict when ovulation will occur as it is different for every woman but it generally occurs round 14 days before your next period is due.

What is the effectiveness of the morning after pill if taken after ovulation?

EllaOne is perhaps the most effective method of emergency hormonal contraception. If taken within 120hrs (5 days) of unprotected sex it can prevent about 95% of pregnancies. It is important to note that it is not 100% effective.

How do I take the morning after pill?

Take One tablet within 120 hours of unprotected sex. The sooner the tablet is taken, the more effective it is likely to be. It can be taken with or without food but take another tablet if vomiting occurs within 3 hours.

What are the possible side effects when using EllaOne?

EllaOne is usually very well tolerated but the following side effects tend to be the most common:

  • Headache
  • Dizziness
  • Feeling sick or tummy pain
  • Irregular bleeding
  • Breast tenderness
  • Tiredness

Will the morning after pill affect my other medication?

EllaOne can interact with a small number of medicines. You must inform us of all medicines that you currently take including prescription only, over the counter, homeopathic and herbal medicines so that we can ensure it is safe for you. EllaOne may reduce the effectiveness of the contraceptive pill. Contraceptive pills should not be taken until at least 5 days after EllaOne. You should use another form of contraception such as condoms during this period and until your chosen method becomes effective. Speak to your pharmacist or doctor for further information.

Can the morning after pill be used twice in the same menstrual cycle?

EllaOne will only cover you for unprotected sexual intercourse in the previous 5 days and It does not cover you for any future unprotected intercourse. You should use condoms or an alternative protective method. • EllaOne is not to be used twice in the same menstrual cycle and you should never take EllaOne and levonorgestrel within the same menstrual cycle as each other.


Each tablet contains 30mg Ulipristal Acetate.
