Delaying your period
Some people may wish to delay their period for a holiday, special occasion, exam or sporting event.
There are medicines that can be prescribed to temporarily delay a period. These medicines are not suitable for everyone, so it is important to discuss your options with a healthcare professional.
What is period-delaying medication?
Period-delaying medication can be used to postpone a period for a short time.
One medicine commonly used for this purpose is medroxyprogesterone acetate (Provera®), which is a synthetic form of the hormone progesterone.
How does it work?
Period-delaying medication works by maintaining progesterone levels, which prevents the lining of the womb from shedding as it normally would during a menstrual cycle.
This delays the start of a period until the medication is stopped.
Who may be suitable?
Period-delaying medication may be suitable for people who:
- have regular periods
- are not currently pregnant
- are generally well
It may not be suitable for everyone. Your clinician will consider your medical history and any medicines you take before prescribing treatment.
How is it taken?
Period-delaying medication is usually started a few days before your period is due.
The exact dose and duration of treatment will depend on your individual circumstances.
Always follow the advice provided by your clinician and do not change the dose yourself.
Possible side effects
Like all medicines, period-delaying medication can cause side effects.
Common side effects may include:
- headaches
- nausea
- bloating
- breast tenderness
- mood changes
- spotting or light bleeding
Most side effects are mild and improve once the medication is stopped.
When should I seek urgent medical advice?
Seek urgent medical attention if you develop:
- swelling, pain or redness in one leg
- sudden chest pain
- sudden shortness of breath
- severe headaches
- sudden changes to your vision
Does period-delaying medication prevent pregnancy?
No.
Period-delaying medication is not a contraceptive and does not prevent pregnancy.
If contraception is required, you should discuss suitable options with a healthcare professional.
Other ways to delay a period
If you use the combined contraceptive pill, it may be possible to delay your period by taking packs back-to-back without the usual break.
You should seek advice from a clinician or pharmacist before making any changes to your usual contraception.
How can I get period-delaying medication?
Period-delaying medication may be available from:
- GP practices
- sexual health services
- pharmacies offering private period-delay services
