How effective is the mini pill?

If used correctly the mini pill can be 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. The mini pill needs to be taken at the same time each day. If it is 3 or more hours late then it will not work correctly.

How does the mini pill work?

The mini pill works by thickening the fluid around the cervix (opening to the uterus/womb). This helps to prevent sperm from entering.

Sometimes the mini pill can also prevent the ovaries from releasing an egg.

How do I use the mini pill?

You take it by swallowing 1 pill (tablet) around the same time every day. It may be helpful to take the mini pill at the same time you do another activity every day (such as cleaning your teeth) or you could enter a reminder into your phone. Once you have taken all the pills in a packet, you start a new packet. The mini pill pack contains 28 hormone pills. There are no sugar pills.

When does it start to be effective?

When you start the mini pill for the first time or after a break it can take up to 3 days to start working to prevent pregnancy. This depends on the timing of your menstrual cycle and if you are already using contraception. Speak with your doctor, nurse or pharmacist for more information.

Where can I get the mini pill?
