Top tips for taking the morning after pill

1. The sooner you take the morning after pill, the better.

Don’t leave any more time than necessary between having unprotected sex and taking the morning after pill. The sooner you take it, the more likely it is to be effective.

2. If you have diarrhoea or vomit after taking it, consult a doctor.

If you are sick or have severe diarrhoea after taking the morning after pill, there is a risk that it won’t work. If this happens, you need to consult a doctor as soon as possible to check whether you need to take a second pill.

3. Make sure you mention any medication you are taking to your pharmacist or doctor.

Certain medications and remedies can stop the morning after pill from working. Before you take the morning after pill, inform your prescribing doctor or your pharmacist of any medication you have recently taken.
