How effective is the Pill?

If used correctly the Pill is over 99% effective at preventing pregnancy. If you miss a pill, vomit within 2 hours of taking a pill, have severe diarrhoea or take certain medications it might only be 93% effective.

What stops the Pill from working?

The pill may not work if:

  • It is taken more than 24 hours late
  • You vomit within two hours of taking it
  • You have very severe diarrhoea
  • You are taking some medications or natural remedies. (Check with your doctor, nurse or pharmacist)

How do I use the Pill?

You take it by swallowing one pill around the same time every day. There are many different brands of the Pill. Most brands come in a 28-day pack that includes both hormone and sugar pills. It is usually recommended to start with a less expensive brand first. Speak to your doctor, nurse or pharmacist for advice. You will usually have your period (bleeding from your vagina) during the sugar pills. You can skip your period by missing the sugar pills and continuing to take the hormone pills.

How does the Pill work?

The Pill works by stopping the ovaries from releasing an egg each month.

It also thickens the fluid around the cervix (opening to the uterus/womb) to prevent the sperm from entering.
