-
Norgeston is an oral contraceptive pill that contains an artificial type of progesterone called levonorgestrel. It’s taken every day without a break and has to be taken within the same 3-hour window each day to protect you from pregnancy. When taken this way, it’s over 99% effective at preventing pregnancy.
Norgeston is manufactured by Bayer and is also known as a progesterone-only pill, POP, or mini pill.
About Norgeston
-
-
Norgeston is a progesterone-only contraceptive pill used to prevent pregnancy. It contains the active ingredient levonorgestrel, which is similar to the progesterone hormone that is naturally produced by the body. Norgeston is commonly known as the mini pill or POP and is a common contraceptive option for people who can not take oestrogen.
-
-
To take Norgeston, you swallow 1 pill whole with water at the same time every day without a break.
Each strip of Norgeston has 35 pills containing 30 micrograms (mcg) of levonorgestrel and has the days of the week printed on it. To take Norgeston, you should:
- start with your first pill on the correct day of the week, as this can help you keep track
- take 1 pill every day following the direction of the arrows on the blister pack
- start a new pack the next day after finishing your current pack of 35 pills
Norgeston can be taken with or without food. If you get side effects like nausea, it might help to take it with food rather than on an empty stomach.
When to start Norgeston
You can start taking Norgeston at any time, but you must continue to take the pill at this time of day going forward. If you start taking it on the first day of your period or within the first 5 days, you will be protected immediately.
If you start to take Norgeston after day 5 of your period, you need to take Norgeston once a day for 2 days to be protected, and you should use condoms during this time if you have sex, or there’s a chance of pregnancy.
You can stop taking Norgeston at any time without having to ‘wean’ off it.
Who can take Norgeston?
Norgeston is suitable for people who:
- are not pregnant
- do not have severe liver disease, liver tumours, or jaundice
- do not have a history of breast cancer or other types of cancer affected by sex hormones
- do not have unexplained vaginal bleeding
- do not have a history of heart attacks or stroke
- are not allergic to any of the ingredients listed in Norgeston
- do not have severe diabetes with changes to their blood vessels
What to do if you miss a pill
If you miss a pill and it is less than 3 hours late, you should take it as soon as you remember. You will still be protected from pregnancy.
If you miss your pill and it has been more than 3 hours, you should take your next pill as soon as you remember, even if it means taking 2 pills in the same day. You will not be fully protected from pregnancy and will need to use extra contraception, such as condoms, for the next 7 days. If you had unprotected sex within the 7 days before your missed pill, you may be at risk of pregnancy. The risk of pregnancy increases if you miss more than 1 pill.

Norgeston contains levonorgestrel and works to prevent pregnancy in 2 main ways:
- thickening the cervical mucus, making it harder for sperm to enter the womb
- preventing the womb lining from thickening, making it more difficult for a fertilised egg to implant and grow in it
Norgeston can also stop ovulation in some people, so that no egg is released to be fertilised.
How long does it take until Norgeston is effective?
If taken on the first day of your period, Norgeston will be effective immediately. If it is taken after the fifth day of your cycle, you will not be protected for 48 hours and should use extra protection, such as condoms.
How effective is Norgeston?
When taken perfectly, Norgeston can be more than 99% effective. However, with typical use, it is around 91% effective. This could include missing the 3-hour window, or having severe vomiting and/or diarrhoea after taking it, which means the medication may not have been absorbed properly.
Norgeston will not protect you against sexually transmitted infections (STIs).
