The Pill is a daily tablet (also known as the combined pill or oral contraceptive pill). The Pill contains two hormones – oestrogen and progestogen. These are similar to the hormones that are produced by the ovaries.

If used correctly the 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 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). This helps to prevent sperm from entering.

You take the Pill by swallowing 1 pill (tablet) around the same time every day. It may be helpful to take the 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.
There are many different brands of the Pill. Most brands come in a 28-day pack that includes both hormone and sugar pills. 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. Speak to your doctor, nurse or pharmacist for more information.

When you start the Pill for the first time or after a break it can take up to 12 days to start working to prevent pregnancy. This depends on whether you start with a hormone pill or sugar pill. It also 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.
Your doctor or nurse will provide a script which you can take to the pharmacy, who will sell you the Pill. Some pill brands are more expensive than other brands. It is usually recommended to start with a less expensive brand first. Some brands will be cheaper if you have a healthcare card.
The Pill may not work if:
Possible side effects for a small number of users can include:
These side effects often settle with time. The Pill has not been shown to cause weight gain.
The Pill causes a very small increase in your chances of a deep vein blood clot/thrombosis, heart attack and stroke. The Pill is associated with a very small increase in the risk of cervical and breast cancer which reduces with time after stopping.
The Pill will not harm the pregnancy. It is safe to continue the pregnancy (and stop the Pill) or to have an abortion.
If you are breastfeeding the Pill cannot be used until your baby is 6 weeks old. After 6 weeks you can use the Pill but other types of contraception might be more suitable choices.
If you are not breastfeeding the Pill can generally not be used until your baby is 3 weeks old. After 3 weeks you can use the Pill if you do not have any medical risk factors (check with your doctor or nurse or pharmacist).
You can stop the Pill at any time and your fertility will quickly return to what is normal for you.
