Heading off on a beach break or city escape? If your period’s due right in the middle of your plans, you’re definitely not the only one looking for a way to shift the timing.

For some people, taking norethisterone — a prescription-only option — might be suggested as part of a short-term plan to delay your period for holiday comfort. But there’s more to it than just timing. This guide explains what to expect, how it works, and why it’s important to speak to a healthcare professional first.

Speak to a Healthcare Professional First

Before anything else, it’s really important to know that period delay tablets, like norethisterone, aren’t available without a prescription. That’s because they’re not suitable for everyone, and they need to be used safely, based on your health history and current cycle.

You’ll need to speak to a healthcare professional, such as our leading pharmacists here at WePrescribe, to check if this kind of treatment is right for you. For instance, anyone with a history of blood clots, liver conditions or hormone-sensitive issues may be advised against it. A quick consultation will also help confirm when to start the tablets, how long to take them for, and how to manage your period delay with minimal side effects.

So even if your plans are coming up fast, try to arrange this chat in good time — it’s the only way to make sure your approach is both safe and tailored to your needs.

Start Norethisterone 3 Days Before Your Period Is Due

If you’re taking norethisterone to delay your period for holiday plans, the usual advice is to start around three days before your period is due. That timing helps stop your body from beginning its normal cycle.

Your prescriber will confirm the best start date based on your usual pattern, so it’s worth keeping track in the lead-up. Starting too late often means it won’t work properly, and starting too early might just extend things unnecessarily.

It won’t be effective once your period has already started, so planning ahead is key. Make sure you’ve got the tablets on hand before you travel, and follow your prescribed routine to keep things on track.

Take the Correct Dosage Regularly

Once you’ve been prescribed period delay tablets, it’s important to take them as directed — usually three times a day, spaced out evenly. This keeps the hormone levels steady and helps stop your period from starting.

Missing doses can make the tablets less effective and might lead to spotting. So, try to build a routine — set phone reminders or keep them somewhere visible if you’re busy or travelling.

If you do miss a dose, don’t take two at once. Instead, speak to one of our prescribers for the right next step.

Being consistent with your norethisterone dosage is what keeps the delay working, so it’s worth being a little extra careful while you’re away.

Continue Taking the Tablets Until You Want Your Period to Start

Once you’ve started taking norethisterone, you’ll need to keep taking it regularly — usually up to the day you want your period to return. This is what holds off the hormonal shift that normally triggers bleeding.

The timing is flexible, which means you can continue for as long as your prescriber advises. But it’s not something to extend on your own — always follow the plan you’ve been given.

When you stop, your period should return within a few days. So it’s a simple way to shift your cycle, as long as it’s done with the right medical support.

Stop Taking the Tablets to Allow Your Period to Begin

When you’re ready for your period to return — whether you’re back from your trip or just feel it’s time — simply stop taking the tablets as directed. Most people find their period arrives within 2 to 4 days after the last dose, though for some, it might be slightly sooner or later.

What shows up can vary a bit — it might be lighter or heavier than usual, and it could take a day or two to get going properly. That’s normal, especially after a short hormonal pause.

If it doesn’t return within a week, or if anything feels off, it’s best to check in with your prescriber — just to make sure everything’s on track.

Be Aware of Potential Side Effects

Like any prescribed treatment, taking norethisterone can come with some side effects, although not everyone gets them. Most are fairly mild and temporary, but it’s still worth knowing what to look out for while you’re on the tablets.

Here are some of the more common norethisterone side effects reported:

  • Mild nausea or an unsettled stomach
  • Headaches that come and go
  • Bloating or a feeling of fullness
  • Breast tenderness or slight discomfort
  • Changes in mood or sleep
  • Spotting or breakthrough bleeding (especially if a dose is missed)

If anything feels unusual or gets worse, or if you notice signs of something more serious (like leg pain or chest tightness), don’t wait — speak to a healthcare professional straight away.

Understand When Not to Use Norethisterone

While many use period delay tablets safely under supervision, norethisterone isn’t right for everyone. That’s why a proper consultation matters — to rule out any risks based on your medical history.

You shouldn’t take it if you:

  • Are pregnant or might be
  • Have a history of blood clots
  • Have liver disease or serious liver problems
  • Have hormone-sensitive conditions (like some cancers)
  • Are experiencing unexplained vaginal bleeding

These factors can impact the safety of the medication for you. Your prescriber will ask the right questions, so just be open — it’s all about keeping things safe and making sure you’re offered the right treatment.

Pack Enough Tablets for the Full Holiday

If you’re planning to delay your period while travelling, make sure you’ve got everything sorted before you go. That includes having the full course of tablets — and a little extra, just in case your return is delayed.

Here are a few tips to keep things smooth:

  • Request your prescription in advance — don’t leave it until the last minute
  • Double-check the norethisterone dosage and total quantity needed
  • The maximum time you can delay your period is 17 days, so the maximum treatment duration is 20 days
  • Keep your tablets in your hand luggage, not your suitcase
  • Carry them in the original packaging with your name and instructions
  • If you’re travelling abroad, bring a copy of your prescription for customs

A little planning goes a long way when it comes to avoiding stress and keeping your cycle under control while away.

 

If you’re thinking about how to stop your period temporarily, the first step is always to speak to a healthcare professional. A quick online consultation can help you understand your options and whether this approach is safe for you.
