Delaying your period isn’t about avoiding nature — it’s about taking control. Whether you’re heading on holiday, planning a wedding, or just want a break from the usual cramps and discomfort, sometimes the timing of your period couldn’t be worse. The good news is, it’s possible to safely delay your period using prescription treatment. In this blog, we’ll look at how a period delay pill works, when to take them, and how to get them quickly and safely through Mentor Pharmacy.
There are all sorts of reasons someone might want to delay their period — and they’re all valid. Life doesn’t always work around your cycle, and sometimes you just want the freedom to feel your best.
If your period often gets in the way, using a period delay pill occasionally can make a big difference.

The most common period delay pill prescribed in the UK is norethisterone. It’s a synthetic form of the hormone progesterone. During your menstrual cycle, your progesterone levels naturally drop, which causes the womb lining to shed — in other words, your period starts.
Norethisterone works by keeping progesterone levels high, which tricks the body into holding off on menstruation. When you stop taking the tablets, hormone levels drop, and your period begins within a few days.
To use a period delay pill like norethisterone effectively, timing is key. You’ll need to start taking it around three days before your period is due to begin.
This method is only intended for occasional use and should not be used as a regular contraceptive. It’s also not suitable for everyone, which is why a quick health check is done before issuing a prescription.
