Norethisterone for period delay

Norethisterone is a prescription medicine used to treat certain gynaecological conditions, but some people ask about using it to delay their period for non‑medical reasons, such as holidays, weddings, sports or other events.

It should be noted that this medication is not suitable for everyone and can increase the risk of blood clots. For this reason, a healthcare professional must always check patient’s medical history before it is prescribed.

In line with national NHS guidance, GP practices are no longer advised to routinely prescribe Norethisterone or similar medicines solely to delay periods for non‑medical reasons. Our practice therefore does not prescribe period‑delay medication for lifestyle or personal events, though we continue to prescribe Norethisterone on the NHS where there is a clear medical reason, it is clinically appropriate and the medicine is suitable for you.

If you wish to use medication to delay your period for a holiday or other personal reason, you can purchase this via certain community pharmacies, some of whom offer an online assessment and home delivery service. It is also available from some private clinics and accredited online doctor services. Please ensure you use a reputable, registered UK‑based provider.
