How does Norgeston work?
The active ingredient in Norgeston is levonorgestrel, a synthetic hormone that mimics a natural hormone in your body called progestogen. It stops you from becoming pregnant by:
Increasing the thickness of the mucus at the neck of your womb (cervix) which makes it harder for sperm to get through.
Reducing the thickness and quality of your womb lining to prevent any fertilised eggs from implanting.
In some women, Norgeston stops the ovaries from releasing eggs although this doesn’t happen to all women who take it.
What is Norgeston used for?
Norgeston is used for contraception - it stops women from getting pregnant. If you are using Norgeston you don’t need to use another method of contraception like a condom to avoid pregnancy, but does not protect women against sexually transmitted infections.
Taken correctly, Norgeston is more than 99% effective, which means that out of every 100 women using it, only one will get pregnant in any one year.
Who can take Norgeston?
Norgeston doesn’t contain any oestrogen type hormones and can be used by women who are unable to take the combined contraceptive pill for reasons such as:
- High blood pressure
- Obesity or being overweight
You may also be able to take a progestogen-only pill if you're over the age of 35 and if you smoke (while combined pills are not recommended in this case).
Who should not take Norgeston?
Although Norgeston is safe for most healthy women, there are some women who it might not be suitable for.
If you think you could be pregnant, stop taking Norgeston and make an appointment to see your doctor. It’s fine to take it while you are breastfeeding.
Other conditions that might make it unsuitable for you include:
- If you have ever had a severe liver disease and your liver function test is not yet back to normal
- If you have ever had a liver tumour
- If you have cancer affected by sex hormones
- If you have any unexplained vaginal bleeding
- If you have ever had a blood clot in your legs or your lungs
- If you have ever had a heart attack or stroke
- If you have had a blood clot in any other part of your body
- If you have severe diabetes with changes to the blood vessels
- If you are allergic to levonorgestrel or any of the ingredients in Norgeston
There are certain conditions that could be affected if you take the contraceptive pill - for a complete list, speak to your doctor or read your patient information leaflet. If you are affected by any of the conditions included you could still be able to take Norgeston, but with regular check ups.
How to take Norgeston
You can take your pill with or without food, preferably with a glass of water. Norgeston pills should be swallowed whole and not chewed. You will need to take it at the same time every day to prevent getting pregnant.
When to start taking Norgeston
It’s best to start taking it on the first day of your menstrual cycle, that is the first day of your period. This protects you from pregnancy immediately.
You can start taking your pill up to the fifth day of your cycle without needing to use any other contraception - unless you have a short menstrual cycle of 23 days or less. If so, you’ll need to use another form of contraception for the first two days.
If you’re not pregnant, you can start taking Norgeston at any time in your cycle, as long as you use another type of contraception too for the first two days.
If you’ve just given birth, Norgeston will protect you against pregnancy immediately if you start taking it on day 21 after giving birth. If you start taking it any later, you’ll need to use a condom or another form of barrier contraception for two days.
If you are starting this pill straight after having a miscarriage or abortion at under 24 weeks, you will also be protected against pregnancy immediately. If you start taking it more than five days afterwards you will need to use extra contraception for the first two days of pill taking.
