Side effects of emergency contraception

Emergency contraception is generally well-tolerated in the body, without causing serious short- or long-term damage to health. However, as with all medications, morning after pills can trigger some adverse effects. These side effects are not severe and generally subside. If you are concerned about any side effects that you experience while taking emergency contraceptive medications such as ellaOne or Levonelle, please consult with your doctor.

What emergency contraception side effects are there?

Emergency contraception side effects are uncommon. But people taking emergency contraception may experience abdominal pain, headache, tiredness, dizziness and breast tenderness. Some women may feel sick and some women may vomit.

Who should not take emergency contraception pills?

Emergency contraception pills are generally suitable for most women over the age of 18. However, pregnant women should not take ellaOne, as the medication will not work. With ellaOne pills you can only take one each menstrual cycle, so it is advisable to use a condom each time you reach your next period, to absolutely minimize the risk of pregnancy.

What should I do if I vomit?

If you vomit 2 or 3 hours after taking an emergency contraceptive pill, this may be a sign that the medication has not worked. Take another emergency contraceptive pill as soon as possible and speak to a doctor or medical specialist.

What should I do if I suffer emergency contraception side effects?

If you suffer emergency contraception side effects, you should speak to a medical professional. You may wish to try a different type of emergency contraceptive medication. Remember that any side effect you are experiencing is likely to wear off quickly.

Delayed period

One emergency contraceptive side effect is that you may experience a delayed period. If your period is more than seven days late, or is at all unusual, you should speak to your doctor. Most women taking the emergency contraceptive pill have a normal period at the expected time.

When to speak to your doctor

Speak to your doctor if you think you may have become pregnant despite taking the emergency contraception pill. You might want to talk to a doctor or nurse if your period is late or shorter than usual, or if you have any sudden pain in your lower abdomen (tummy).
