If your period is due during a holiday, it may be possible to delay it. The right approach depends on whether you already use hormonal contraception, when your next period is expected and whether period-delay treatment is suitable for you.
For people who are not already using a suitable combined contraceptive pill, norethisterone is the only progestogen licensed in the UK specifically for postponing menstruation. For period delay, it needs to be started before the expected period rather than once normal bleeding is already established.
If you already take certain types of combined contraceptive pill, it may instead be possible to delay the withdrawal bleed by changing how you take your pill packs. This depends on the type of pill you use.
Can you stop your period for a holiday?
It is more accurate to think about delaying an expected period rather than instantly stopping one.
If your period has not started yet, a prescriber may consider period-delay treatment after checking that it is suitable for you. Norethisterone is normally started at least three days before the expected period.
If normal menstrual bleeding has already begun, the usual period-delay course should not be treated as an on-demand way to stop that bleed. Starting late does not simply make the same treatment work faster.
If you are already bleeding, read our guide to starting norethisterone after a period has begun rather than changing the dose yourself.
What tablets can delay your period for a holiday?
Norethisterone
Norethisterone is a synthetic progestogen and is licensed in the UK for postponement of menstruation. The standard licensed period-delay regimen uses norethisterone 5mg three times a day, starting three days before the expected period.
It works by maintaining progestogen activity so that the hormonal change that normally leads to menstrual bleeding is postponed while treatment continues.
Norethisterone is not contraception. If pregnancy prevention is needed during your holiday, you will still need an appropriate contraceptive method.
For the detailed regimen, missed-dose information and treatment timing, see the norethisterone dosage guide.
If you already take the combined contraceptive pill
People already using certain combined contraceptive pills may be able to delay their withdrawal bleed by taking active pill packs back-to-back or using another tailored regimen.
For example, someone using a monophasic 21-day pill may be advised to start the next packet without the usual pill-free break. Everyday pill packs may require the inactive tablets to be skipped. The correct approach depends on the specific pill, so check the leaflet or ask a pharmacist, nurse or doctor before changing how you take it.
Breakthrough bleeding can still happen when pill-free breaks are reduced or removed.
What about the mini pill?
The progestogen-only pill is taken continuously rather than with the traditional seven-day pill-free break used by some combined pills. Its effect on bleeding patterns can vary, so it should not be assumed that starting or changing a mini pill will reliably prevent a period for a particular holiday.
If you already use hormonal contraception, tell the healthcare professional exactly which product you take before trying to alter your bleeding pattern.
When should you start period delay tablets before your holiday?
Plan from the date your period is expected, not simply from your flight date.
For the licensed norethisterone period-delay regimen, treatment should start at least three days before the expected onset of your period.
For example, if your period is expected on Friday, the normal start point would be Tuesday, assuming treatment has been prescribed and you have been told to follow that regimen.
This is why it is sensible to arrange any required clinical assessment with enough time before travel. Leaving it until the day before your period is expected may mean the standard treatment window has already passed.
Do not take extra tablets or change the prescribed timing to compensate for starting late.

What if your holiday is soon?
What matters is how close you are to the expected start of your period.
| Your situation | What to consider |
|---|---|
| Your period is more than three days away | There may still be time for assessment and, if appropriate, period-delay treatment. |
| Your period is due within three days | Seek advice promptly rather than assuming the standard regimen can simply be started late. |
| Your period has already started | Standard period-delay treatment is not a reliable way to stop an established normal period. |
| Your cycles are irregular | Timing can be harder to predict, so individual advice is useful before choosing a start date. |
| You already take hormonal contraception | The most appropriate approach may depend on the exact contraceptive you use. |
If your dates are uncertain, give the prescriber as much information as possible about your usual cycle rather than guessing.
Can you stop a period once it has already started?
Norethisterone used for period delay is intended to begin before the expected period.
Once a normal period is underway, taking the standard period-delay regimen is not a dependable way to make the bleeding stop. Norethisterone has other licensed uses involving abnormal or heavy bleeding, but those use different clinical regimens and should not be copied for holiday period delay.
Do not take additional tablets or use a different dosing schedule without advice.

How to take norethisterone for your holiday
The usual dose is one 5mg tablet taken three times a day. You start three days before your period is due and keep taking it for as long as you want to delay, typically until your holiday is over. Norethisterone can usually delay your period for up to around 17 days. Once you stop the tablets, your period normally returns within two to three days.
For example, if your period is due on the 12th and you fly home on the 20th, you would start norethisterone on the 9th, take it three times a day across your trip, and stop when you are ready for your period to return.
For the full breakdown, see our norethisterone dosage guide. Your exact dosing is also confirmed by the prescriber and printed on your medication, and you should always follow the instructions on your dispensing label.
How long can you delay your period?
NHS Specialist Pharmacy Service guidance states that norethisterone can be taken for up to three to four weeks if necessary for period delay. The actual duration prescribed should reflect your circumstances and the prescriber's assessment.
That does not mean everyone should use it for the maximum duration.
Follow the course stated on your dispensing label and do not extend treatment simply because your holiday changes or you decide you would like to delay your period for longer.
When will your period return after stopping the tablets?
With the licensed norethisterone period-delay regimen, menstruation usually returns within about three days after treatment is stopped, although individual timing can vary.
If your period does not return and pregnancy is possible, take appropriate advice before considering another course.
Will period delay tablets definitely stop your period?
No treatment can guarantee a completely bleed-free holiday for everyone.
Individual response varies, and spotting or breakthrough bleeding can occur even when treatment has been taken correctly. NHS Specialist Pharmacy Service guidance specifically notes that the effectiveness of period-delay treatment can vary between individuals.
Taking more than the prescribed amount does not guarantee a better result and may increase risk.

Are period delay tablets suitable for everyone?
No. Norethisterone is a prescription-only medicine, and a healthcare professional needs to check whether it is appropriate for you.
Your health history, possibility of pregnancy, previous blood clots, liver problems, unexplained vaginal bleeding and other medicines can all be relevant to the decision. The official patient information leaflet also lists important warnings, contraindications and potential side effects.
Give accurate information during your assessment, including all prescription medicines, non-prescription medicines and herbal products you use.
For more detail about possible effects and warning symptoms, read Medicina Pharmacy's norethisterone side-effects guide.
Does a period delay pill prevent pregnancy?
No.
Norethisterone prescribed for period delay is not a contraceptive and should not be relied on to prevent pregnancy.
If you need contraception while travelling, use an appropriate contraceptive method and seek advice if you are unsure what is suitable alongside period-delay treatment.
Planning period delay for your holiday
If you know your travel dates and approximately when your period is expected, plan ahead rather than waiting until bleeding is about to start.
You can review Medicina Pharmacy's period-delay treatment information if you want to understand the current consultation-led treatment route.
An online assessment does not guarantee that norethisterone will be prescribed or supplied. A prescriber needs to decide whether treatment and the proposed timing are appropriate for you.
