Norethisterone (Period Delay)

Delaying a period for up to about 17 days.

Norethisterone keeps the womb lining in place, so it is not shed until you stop the tablets. Your period usually starts 2 to 3 days after the last tablet.

Women who want to delay a period and have no history of blood clots, stroke, heart attack or liver problems. It is not a contraceptive.

Order online and we review your request. A prescriber checks your consultation form for clinical appropriateness and contacts you if anything else is needed. Once approved, your medication is dispensed and delivered to your door.

Side effects vary. Common effects may include nausea, headache, and gastrointestinal disturbances. Please refer to the patient information leaflet supplied with your medication for a complete list. Report any unexpected or severe side effects to your prescriber or pharmacist.

Do not take if you have had a blood clot (DVT or pulmonary embolism), stroke or heart attack, have liver disease, unexplained vaginal bleeding, or breast cancer, or if you might be pregnant.

Tell us about all medicines you take. Some epilepsy medicines, some antibiotics (rifampicin) and St John's wort can stop it working.

Must not be taken if you are or might be pregnant. Not recommended when breastfeeding.

Take one 5mg tablet three times a day, starting 3 days before your period is due, for as long as you need to delay it (up to 17 days). It does not prevent pregnancy, so use condoms if you have sex. Seek urgent help if you get calf pain or swelling, chest pain, breathlessness or sudden headache.
