Noriday is a progestogen-only contraceptive pill, also known as the mini-pill. You can take Noriday instead of contraceptive pills that contain oestrogen and it’s just as effective at preventing pregnancy.
You take 1 Noriday pill at the same time each day, without taking a break, for continuous protection.
Norethisterone is the active ingredient in Noriday and each pill contains 350 micrograms of norethisterone. Noriday is made by Pfizer.

Noriday is a contraceptive pill you can use to prevent pregnancy. You take it by swallowing 1 pill at the same time every day.
Noriday contains norethisterone, which is a progestogen that is similar to the hormone progesterone.
Progesterone is a female sex hormone found naturally in your body and is involved in regulating your menstrual cycle. When you have high levels of progesterone, your body is less likely to release an egg through ovulation. This is how Noriday prevents pregnancy.
Start the first strip of Noriday pills on the first day of your period. You will need to use extra contraception, such as condoms, for the first 7 days of taking Noriday.
Each blister strip is marked with the days of the week. The arrows along the foil will help you to remember to take a pill each day.
To take Noriday, make sure you:
- swallow 1 pill each day with a glass of water
- take the pill at the same time each day
Once you’ve finished a strip of Noriday pills, you can start the next one the following day. You will not need to take a break between strips and you will take Noriday throughout the time you would normally have your period.
You might experience some breakthrough bleeding or light spotting while taking Noriday.
What if I miss a pill?
If you forget to take your Noriday pill, you’ll need to take the missed pill as soon as you remember and continue taking your pills as normal. This might mean taking 2 pills on the same day.
You should use extra contraception if it has been more than 3 hours since you forgot to take your pill. Use condoms for the next 7 days after a missed pill. If you have had sex since you forgot to take your pill then you may want to consider using emergency contraception.
If you’re sick or have diarrhoea you can continue to take Noriday as normal. You should use a condom during the time you are unwell if you plan on having sex, and for the next 7 days after.
Noriday works to prevent pregnancy by:
- thickening the fluid at the entrance to your womb (cervix), making it hard for sperm to get through
- stopping a fertilised egg growing in your womb
- stopping your ovaries from releasing eggs
It’s important to remember that Noriday does not prevent you from getting sexually transmitted infections (STIs). To protect against STIs, you should use condoms.
Noriday is more than 99% effective at preventing pregnancy when you take it perfectly every single day.
It’s not always easy to remember to take a pill every day. If you have missed a pill and have followed our missed pill advice, Noriday is around 91% effective in preventing pregnancy.

- weight changes
