The Contraceptive Mini Pill
The mini pill is also known as the progestogen-only contraceptive pill. It is a progestogen-only oral contraceptive pill (POP) which is taken at the same time every day to prevent pregnancy.
Progestogen is similar to the hormone produced by the ovaries in the female body.
In Australia the mini pill is sold as Microlut®, Locilan® and Noriday®.
The mini pill works by:
- thickening the mucus of the cervix so that sperm cannot enter the uterus (womb)
- affecting ovulation (egg release from the ovary) in some users
When you take the mini pill for the first time or after a break, it can take up to three days to start working.
Speak with a doctor, nurse or pharmacist about the best way to get started.
- Taken correctly, the mini pill can be 99.5% effective at preventing pregnancy.
- If you miss a pill, vomit within two hours of taking a pill, are more than three hours late in taking the pill and have severe diarrhoea or take certain medications, this can reduce to 93% effective.
The mini pill might not be right for you if you:
- find taking a tablet at the same time each day difficult
- have been treated for breast cancer
- have severe liver disease
- are taking certain types of medication might stop the mini pill from working (see your doctor or pharmacist).
Starting the mini pill for the first time requires an assessment by a doctor.
They will explain how to use the mini pill and give you a prescription (script).
The cost of the mini pill is largely dependent on whether you have a Concession and/or Medicare card.
The mini pill is available from any pharmacy with a script.

- Reversible, with a rapid return to usual fertility once stopped.

- mood changes.
The mini pill has not been shown to cause weight gain.
You need to take the mini pill at the same time every day.
The pack contains 28 hormone pills. There are no sugar pills (non-hormone pills).
We recommend you set a reminder on your phone or calendar to help you remember to take the mini pill.
The mini pill might not work if you:
- take it more than three hours late
- have had severe diarrohea
- vomit within two hours of taking it
- are taking certain medications and natural remedies (check with your doctor).
- Take the missed pill as soon as you notice (this may mean you may be taking two pills on the same day).
- Use condoms for the next three days.
- Continue to take your pills as normal.
If you have had unprotected sex since you missed your pill, you may need to take emergency contraception.
