What is Norethisterone?
Norethisterone is a period delay medication. Period Delay Tablets are a prescription treatment, used to delay your next period for up to 17 days. They contain an ingredient called a progestogen, which is similar to the natural female hormone progesterone.

– Medicines to treat epilepsy (e.g. phenytoin, carbamazepine)
– Antibiotic medicines to treat an infection (e.g. tetracyclines, rifampicin, co-trimoxazole) – Antiviral medicines to treat HIV (e.g. ritonavir, nelfinavir)

Is there any reason why I would not be able to take Norethisterone?
Some women using hormonal contraceptives including period delay pills have reported depression or depressed mood. Depression can be serious and may sometimes lead to suicidal thoughts. If you experience mood changes and depressive symptoms contact your doctor for further medical advice as soon as possible.
Risk of Venous Thromboembolism (VTE)
All women have a small chance of having a blood clot in the veins of the leg, in the lung or other part of the body. The chances of getting a clot are very slightly higher if you are taking a hormone medicine. You are more likely to get a clot whether or not you are taking period delay tablets if you:
– are very overweight
– have systemic lupus erythematosus. (This is a condition where the immune system attacks healthy tissues, typically causing symptoms such as painful joints and muscles, tiredness, fever and rashes).
– have had a blood clot in the veins or lungs before
– have relatives who have had blood clots
– are unable to move for long periods of time (for example after an operation)
– have a serious injury or have major surgery
– have a history of repeated miscarriage.
Tell your doctor if you have just had an operation or if you are going to have an operation while taking period delay tablets. Section 4 of this leaflet (‘Possible side effects’) also has more information on the warning signs of blood clots.
Why should I take Norethisterone?
Periods can be inconvenient. Norethisterone lets you safely delay your period so that you can focus on what’s important.
Will Norethisterone affect my cycle?
Norethisterone won’t effect your normal cycle. Your period will commence shortly after you take the last dosage.
