There are times when having your period can be inconvenient — during holidays, important events, religious observance, sports competitions, or even a honeymoon. In such cases, many women turn to a period delay pill to postpone their menstrual cycle safely and temporarily.
At Mendus Pharmacy, we provide convenient, pharmacist-led access to period delay medication, including norethisterone, the most commonly used option in the UK. In this guide, we’ll explain exactly how the period delay pill works, who can use it, when to start taking it, and what to expect throughout the course.
What Is the Period Delay Pill?
The period delay pill is a hormonal medication that contains norethisterone, a synthetic version of the hormone progesterone. In a natural menstrual cycle, progesterone levels drop towards the end of the cycle, triggering the shedding of the womb lining — which results in your period.
By taking norethisterone, you artificially maintain progesterone levels, preventing this drop and therefore delaying your period until you stop taking the medication.
It’s important to understand that the period delay pill is not a form of contraception. It will not protect you from pregnancy, so if you’re sexually active, you’ll need to use additional contraception.
Who Can Use the Period Delay Pill?
The period delay pill is generally suitable for women aged 16 to 50 who:
Have regular periods
Are not using hormonal contraception
Do not have a history of blood clots, liver disease, or hormone-sensitive cancers
Are not currently pregnant or breastfeeding
At Mendus Pharmacy, a pharmacist will assess your suitability before prescribing norethisterone. You may be asked questions about your medical history, menstrual cycle, and any medications you’re currently taking.
Women already on the contraceptive pill may be advised to manipulate their current pill pack instead of taking norethisterone — your pharmacist can guide you accordingly.
When to Start Taking It
Timing is crucial for the period delay pill to be effective. You should begin taking the medication three days before your period is due.
For example, if your period is expected on a Friday, you should start taking norethisterone on the Tuesday. If you start too late — for instance, the day before or the day your period is due — the medication may not work effectively, and bleeding could still occur.
That’s why it’s helpful to track your cycle and plan ahead, especially if you have an upcoming event or holiday.
Dosage and How to Take It
The standard dosage of norethisterone for delaying a period is:
5mg, taken three times a day (morning, afternoon, and evening)
Start three days before your period is due
Continue for up to 17 days
This will delay your period for the duration that you continue taking the tablets. Once you stop taking norethisterone, your period will usually begin within 2 to 4 days.
It’s important to take the tablets consistently and not miss any doses. Setting reminders can help, particularly if you’re travelling or attending a busy event.
How Long Can You Take It For?
Norethisterone is designed for short-term use only, typically to delay your period for up to 17 days. It should not be taken continuously or used to skip multiple periods in a row unless advised by a doctor.
Taking the period delay pill too frequently or over a long period may increase the risk of side effects and is not recommended for regular cycle management.
If you’re looking for a longer-term solution to manage periods or reduce menstrual symptoms, your pharmacist or GP can discuss alternative options such as the combined contraceptive pill, hormonal coil, or injection.
Side Effects to Be Aware Of
Most people tolerate the period delay pill well, but some may experience:
Nausea
Headaches
Breast tenderness
Bloating
Mood changes
Spotting or light bleeding
These side effects are usually mild and resolve after stopping the medication. If you experience anything unusual or severe, speak to a healthcare professional.
