Delaying a period for holiday/sport 

The Chowdhury Practice is no longer able to prescribe norethisterone for period delay, particularly for non-medical reasons like holidays, due to changes in prescribing guidelines and a focus on resource allocation. Norethisterone, a medication used to delay periods, is now often available over the counter at pharmacies, or through private healthcare providers, for those seeking period delay for non-urgent reasons. 

The change in prescribing practices reflects a shift in priorities within the NHS, focusing on efficient resource allocation and encouraging individuals to access period delay medication through other available channels like private providers and pharmacies, particularly for non-medical reasons. 

The National Institute for Health and Care Excellence (NICE) updated its guidelines in May 2025, stating that period delay medication should not be routinely prescribed on the NHS for non-medical reasons like travel.

Norethisterone is available through private providers, including pharmacies, allowing individuals to access it without needing a prescription from their GP for non-medical purposes. 

While generally considered safe, norethisterone can cause side effects like nausea, headaches, and breast tenderness, and it may not be suitable for individuals with certain medical conditions or risk factors, such as a history of blood clots.
