About ellaOne

Ellaone is a type of emergency hormonal contraception (morning after pill UK) that uses the active ingredient Ulipristal acetate.

Ellaone modfies the effects of the progesterone hormone in the body and resultantly delays or inhibits ovulation (releasing the egg from the ovaries). This reduces the chances of conception. 

Ellaone can be effective if taken up to 5 days (120 hours) of an incident of unprotected sex, however a general rule is that the sooner it is taken, the more effective it is. 

In the UK,  the Ellaone Morning After Pill is accessible at most pharmacies (and online providers such as Meds For Less) over the counter. 

EllaOne works by using it’s active ingredient – Ulipristal acetate – to block or delay ovulation.

Ulipristale modifies the effect of normal progesterone hormones in the body, this is what results in the ovulation delay. The effect allows the ovulation process to be delayed till the sperm can no longer fertilise the egg. 

EllaOne does not affect the implantation of a fertilised egg into the womb, neither does it affect an active pregnancy , it only works to block fertilisation. 

EllaOne can be taken upto 5 days after unprotected sex, this is because sperm can stay active for 5 days in the female reproductive tract. This delay helps prevent any egg releases that time which can result in fertilisation. 

EllaOne taken after ovulation can have less effective results in preventing pregnancy.

EllaOne comes as a single 30mg tablet that is swallowed with water, it can be taken at any point in the menstrual cycle but it should be taken as soon after unprotected sex to ensure maximum effectiveness. 

It should also ideally be taken before ovulation as it’s main mechanism of action is to delay ovulation. Once the egg is released into the female reproductive tract, EllaOne has little effective in reducing the chance of a conception.

Unlike the Levonorgestrel-based morning-after pill, EllaOne cannot be used as routine birth control. 

The following is an overview of how different factors affect the effectiveness of EllaOne.

EllaOne is designed to work as a Plan B Pregnancy Pill by inhibiting or delaying ovulation. Hence it’s main mechanism of action is intended to work before ovulation. 

If ovulation has already occurred, EllaOne is unlikely to be effective as the egg may already be in the female reproductive tract and really for fertilisation. 

This pre-and-post Ovulation timining is important as sperm can survive in the reproductive tract for 5 days. Therefore it is imperative that the pill be taken before ovulation in order to prevent fertilisation. 

If you have already gone past the point of ovulation in your cycle, or you suspect that ovulation has occured, then the copper IUD maybe a more effective form of emergency contraception. 

EllaOne remains an effective method of birth control if taken within 72-120 hours of unprotected sex. It is most effective if taken as soon as possible after sex, (most effective after 24 hours, very effective between 24-72 hours and still highly effective between 72-120 hours). Additionally, EllaOne should ideally be taken before ovulation.

EllaOne starts to work as soon as you take it, the active ingredient Ulipristal Actetate quickly blocks or delays the hormonal signals that trigger ovulation. 

EllaOne is absorbed into your system a few hours after taking the tablet. If it is taken before ovulation, it can inhibit or delay the release of the egg by atleast 5 days. This is long enough for any sperm in the reproductive tract to die off. 

If ovulation has already occurred, EllaOne is less likely to prevent pregnancy as it does not prevent implantation of a fertilised egg into the womb, nor does it breakdown an active pregnancy. 

Some factors influence the effectiveness of EllaOne, such as:

  • BMI or Body weight: EllaOne may be less effective in women with BMIs < 30 Kg/m2 or those who weigh more than 85 kg. 
  • Timing of Ovulation: If ovulation has already occurred, EllaOne is less likely to prevent pregnancy
  • Vomitting: If you vomit within 3 hours of taking the medicine, consider the medicine forfeit and the dose not absorbed. In these circumstances, it is best to  take a replacement dose. 
  • Drug interactions: Taking other medications, such as certain anti-epileptics, antibiotics, or some herbal remedies, can affect the effectiveness of EllaOne.  If you are taking any other medication, please consult your healthcare advisor about the safety of taking EllaOne. 
  • Breast feeding: It is advisable not to take EllaOne while breastfeeding. If you do, you should pump and discard breast milk for a week to avoid the hormonal effects of the drug reaching the baby.

Like all medicines, EllaOne has some side effects however, not everyone will experience them. Those that do will find that they are usually mild and short lived.

Common but mild side effects of EllaOne usage include:

  • Headache
  • Nausea 
  • Abdominal pain
  • Periods being a bit late or earlier than usual

Uncommon but bit more moderate side effects of EllaOne usage include:

  • Dizziness
  • Mood changes (feeling low, anxious or irritable)
  • Fatigue
  • Muscle pain or back pain

Rare but extremely serious side effects include:

  • Rash, itching or allergic reactions 
  • Significant changes in menstrual cycle (period delayed by more than 7 days or very heavy bleeding). 

If you experience any of these serious but very rare reactions, please consult a healthcare advisor as soon as possible.

EllaOne is not the only emergency contraceptive pil option. There are other options for next day emergency contraception, such as: Levonelle or the copper IUD. 

The Copper IUD is a very effective form of emergency contraception (99% success rate) which can be both long term or short term. It is a T-shaped device that can be inserted into the uterus that releases copper ions into the female reproductive tract. These copper ions are toxic to the sperm and thereby prevents fertilisation. 

As a form of emergency contraception, it can be inserted upto 5 days after unprotected sex and can stay in place for atleast 5-10 years (if you so choose) before it needs to be removed. 

To find more information about the copper IUD including about insertion or side effects, please speak to your healthcare advisor.

Levonelle is an emergency contraceptive pill that uses a different active ingredient than EllaOne.

The active ingredient in Levonelle is Levonorgestrel while the active ingredient in Ulirpristal acetate is EllaOne.

Levonelle can be taken up to 3 days (72 hours) after unprotected sex and remains highly effective during that time period. In contrast, EllaOne can be taken up to 5 days (120 hours) after an incident of unprotected sex.

EllaOne retains a high degree of effectiveness over the 3-5 day window in which it is meant to be taken. Levonelle, on the other hand, is very effective for the first 24 hours after which its effectiveness starts to drop.

EllaOne is not suitable for women who are breastfeeding. It is advisable to pump and discard breast milk one week after taking it. Levonelle is safe to use while breastfeeding.
