Many patients take Noriday free of side effects however, like all medicines, some people may experience some side effects. The severity can vary from person to person.
Side effects such as bleeding between periods or feeling nausea are more common in the first three months. However, they should soon disappear. If the side effects become intolerable, worsen, or continue beyond three months, you should contact your doctor or The Family Chemist clinician.
A rare side effect (1 in 10 in every 10,000 users) can occur in women taking Noriday: a harmful blood clot in a vein or artery. Seek urgent medical attention if you notice any swelling of one leg, pain or tenderness, increased warmth in the affected leg, change in colour of the skin on the leg, sudden unexplained breathlessness or rapid breathing, sharp chest pain, severe lightheadedness, rapid or irregular heartbeat or severe pain in your stomach. The patient information leaflet contains more information regarding recognising a blood clot.
You are more at risk of having a blood clot:
▪ as you get older
▪ if you smoke
▪ if you are seriously overweight
▪ if you have some diseases of the heart and blood vessels
▪ if you have diabetes
▪ if you suffer from migraines
▪ if you’re off your feet for a long time because of major surgery, injury or illness ▪ if you or any of your close family have had blood clots
▪ if you have varicose veins

A few women have irregular periods, a little unexpected bleeding or spotting or no periods at all while taking Noriday, especially during the first few months. Normally, these changes are nothing to worry about and require no treatment. Keep taking Noriday as usual. The problem should disappear after the first few strips.
You may also have unexpected bleeding if you are not taking your pills regularly, so try to take your pill at the same time every day. Also, unexpected bleeding can sometimes be caused by other medicines.
Make an appointment to see your doctor if:
You get breakthrough bleeding or spotting that:
- carries on for more than the first few months
- starts after you’ve been taking Noriday for a while
- carries on even after you’ve stopped taking Noriday.
You have had no period for six weeks.
