Side effects


1. Before you take Noriday

Noriday may not be suitable for all women. Do not take Noriday if you have ever had any of the following:

• cancer of the breast, cervix, vagina, or womb

• malignant or benign liver tumours

• liver problems, for example jaundice (yellowing of the skin or eyes)

• pruritus (itching all over your body) or jaundice while you were pregnant

• high levels of fat in your blood

• vaginal bleeding for which your doctor could not find the cause

• amenorrhoea (lack of periods)

• thrombophlebitis (inflamed veins), coronary artery disease, heart attack, angina, blood clots, or a stroke

• a disease of your red blood cells, such as sickle cell anaemia

• an allergic reaction to any of the ingredients in Noriday

Also, please tell your doctor if you could be pregnant. You should not be taking Noriday if there is a possibility that you may be pregnant.

► Tell your doctor if you suffer from any of the following conditions, as some diseases may get worse when you are taking the contraceptive pill:

• epilepsy

• migraine

• heart or kidney problems

• depression

• diabetes

• varicose veins

• gallstones

• asthma

• high blood pressure

• tetany (muscle twitches)

• multiple sclerosis

• porphyria (a rare inherited blood disease)

• otosclerosis (an inherited form of deafness which may get worse during pregnancy)

If any of these get worse, or if you get them for the first time, your doctor may tell you to stop taking Noriday.

Noriday tablets contain lactose.

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

Your doctor or clinic will give you regular checkups while you are taking Noriday. Your blood pressure will be checked before you start the pill and then at regular intervals whilst you are on the pill. If your blood pressure goes up, your doctor may tell you to stop taking Noriday. Your breasts and reproductive organs may also be checked, including taking a cervical smear at regular intervals if this is considered necessary by the doctor.

2. Breast Cancer

Every woman is at risk of breast cancer whether or not she takes the pill. Breast cancer is rare under 40 years of age but the risk increases as a woman gets older.

Breast cancer has been found slightly more often in women who take the pill than in women of the same age who do not take the pill. If women stop taking the pill, this reduces the risk, so that 10 years after stopping the pill, the risk of finding breast cancer is the same as for women who have never taken the pill. Breast cancer seems less likely to have spread when found in women who take the pill than in women who do not take the pill.

It is not certain whether the pill causes the increased risk of breast cancer. It may be that women taking the pill are examined more often, so that breast cancer is noticed earlier. The risk of finding breast cancer is not affected by how long a woman takes the pill, but by the age at which she stops. This is because the risk of breast cancer strongly increases as a woman gets older.

● In 10,000 women who take progestogen-only pills like Noriday for up to 5 years but stop taking it by the time they are aged 20, it is estimated that less than 1 additional case of breast cancer would be found up to 10 years afterwards, compared with the number found in 10,000 women who had never taken the pill. For 10,000 women who take a pill like Noriday for 5 years and stop it by the age of 30, there would be 2 or 3 extra cases of breast cancer found up to 10 years afterwards, (in addition to the 44 cases of breast cancer found in 10,000 women in this age group who have never taken the pill).

● For 10,000 women who take Noriday for 5 years and stop it by the age of 40, there would be about 10 extra cases found up to 10 years afterwards (in addition to 160 cases of breast cancer found in 10,000 women in this age group who had never taken the pill).

● The possible small extra risk of being diagnosed with breast cancer has to be weighed against the known benefits of taking the progestogen-only pill.

Taking any medicine carries some risk. You can use the information in this leaflet, and the advice your doctor or clinic has given you to weigh up the risks of taking the pill. Don’t be embarrassed, ask as many questions as you need to.

3. Other medicines and Noriday

Some medicines may stop Noriday from working properly. These include some drugs that treat epilepsy, arthritis, some antibiotics and sedatives. If you take any other medicines while you are taking Noriday, make sure that your doctor knows. You will be advised whether you need to use additional contraceptives while you are taking the medicine.

The herbal remedy St John’s wort (Hypericum perforatum) should not be taken at the same time as this medicine. If you already take a St John’s wort preparation, stop taking the St John’s wort and mention it to your doctor.

4. Smoking

Smoking increases the risk to your health and increases some of the risks of the combined pill. It is not known if these risks also apply to the progestogen-only pill. It is best to stop smoking anyway.

What do I do if I become pregnant whilst taking Noriday?

If you suspect that you might be pregnant, seek confirmation and see your doctor immediately. Stop taking the tablets and use another method of contraception until you are sure that you are not pregnant.

Noriday can increase your risk of having an ectopic pregnancy (a pregnancy developing outside of the womb).

The exposure of the foetus to sex hormones such as Noriday has been shown to be associated with an increased rate of birth defects such as heart and limb malformations. Please discuss how advisable a continuation of any pregnancy under Noriday is with your doctor.
