Women’s health deserves clarity, respect, and reliable access to treatment. At The Care Pharmacy, we are proud to support women across the UK with safe, regulated access to period delay treatment, including norethisterone tablets. In this guide, we explain how they work, when to take them, what to expect, and how to use them safely.
Norethisterone tablets are a prescription-only medication used to delay your period temporarily. They contain a synthetic form of progesterone, a natural female hormone that helps regulate the menstrual cycle.
Normally, a drop in progesterone levels triggers your period. Norethisterone works by maintaining progesterone levels in your body, preventing the lining of the womb from shedding. As a result, your period is delayed until you stop taking the tablets.
These tablets are commonly used for:
They are not a contraceptive and do not protect against pregnancy.
To understand how norethisterone tablets work, it helps to know what happens in a natural menstrual cycle. After ovulation, progesterone rises to prepare the womb for pregnancy. If pregnancy does not occur, progesterone levels fall, and menstruation begins.
Norethisterone acts like progesterone. By continuing to supply this hormone in tablet form, it prevents the hormonal drop that would normally trigger bleeding.
When you stop taking the tablets, hormone levels fall and your period usually starts within two to three days.
Timing is important. To delay your period successfully, norethisterone tablets should be started three days before your expected period date.
The standard dose is:
You can continue taking the tablets for up to 17 days if needed. Once you stop, your period typically begins within 48 to 72 hours.
Starting the medication too late may mean it does not work effectively. If you are unsure about your cycle dates, it is important to discuss this during your consultation. Get in touch with our team to get personalised advice.
You can delay your period for up to 17 days using norethisterone tablets. This provides flexibility for most short-term events or travel plans.
It is not recommended for long-term cycle suppression without medical supervision. If you regularly need to delay your period, there may be alternative hormonal options that suit you better.
Most women tolerate norethisterone tablets well. However, like all medications, side effects can occur.
Common side effects include:
Less commonly, some women may experience spotting or breakthrough bleeding.
These side effects are usually temporary and settle once the medication is stopped.
Some women experience light spotting or breakthrough bleeding while taking norethisterone. This usually occurs if doses are missed or taken inconsistently, which can cause hormone levels to fluctuate. It does not necessarily mean the medication has failed or is unsafe. Taking the tablets at evenly spaced times each day helps reduce the likelihood of this happening.
Norethisterone tablets are suitable for many women who want to delay their period temporarily.
You may be eligible if you:
During your online consultation, we will assess your suitability carefully. We review your medical history, current medications, and any risk factors to ensure treatment is safe for you.
Norethisterone may not be suitable if you:
This is why an honest and accurate consultation is essential before starting treatment.
Norethisterone tablets are widely used and generally safe for short-term use. However, as a synthetic hormone, they do carry some risks.
There is a small increased risk of blood clots, particularly if you:
Our prescribing team will assess your individual risk profile before issuing a prescription.
Norethisterone 5mg does not affect long-term fertility. It works temporarily to delay menstruation by maintaining progesterone levels, but it does not permanently alter your cycle. Once you stop taking the tablets, ovulation and your natural hormonal rhythm resume.
Key points to remember:
Most women return to their regular cycle pattern within one month.
If you are using period delay tablets for travel, maintaining a consistent dosing schedule is essential for effectiveness. Taking the medication three times daily at evenly spaced intervals helps keep hormone levels stable.
When travelling, consider the following:
Planning ahead reduces the risk of breakthrough bleeding and ensures your period remains delayed as intended.
Accessing norethisterone tablets through a trusted online pharmacy offers convenience, privacy, and speed. However, it is vital to choose a regulated UK provider.

Our goal is to provide safe medical support so you can make informed decisions about your body and your commitments.

Below are some common questions our team get asked about period delay pills. Click on each question to get the answers you are looking for.
You must start norethisterone tablets three days before your expected period. If taken at the correct time and dose, they are highly effective at delaying menstruation.
Moderate alcohol consumption does not directly affect how norethisterone works. However, excessive alcohol can increase certain health risks, including clotting risks in some individuals.
Some women notice a slightly heavier or lighter bleed after stopping. This typically settles within one cycle.
It is designed for occasional use. If you frequently need to delay your period, speak to a clinician about longer-term hormonal options.
Take it as soon as you remember, unless it is close to your next dose. Missing doses may increase the chance of breakthrough bleeding.
No. Norethisterone tablets do not prevent pregnancy.
If you are sexually active and do not wish to conceive, you should use appropriate contraception while taking them. If you are already using the combined contraceptive pill, you may have other options for delaying your period.
Our healthcare team can advise you on the safest approach during your consultation.
Timing is crucial when taking norethisterone tablets. They must be started three days before your expected period. If you begin treatment too late, especially once progesterone levels have already started to fall, the medication may not prevent bleeding. In this case, your period may still begin, or you may experience breakthrough spotting. Tracking your cycle accurately helps ensure the tablets work effectively.
Because norethisterone influences progesterone levels, some women notice changes in premenstrual symptoms. It may reduce certain PMS symptoms in some individuals, while others may experience mild mood changes or bloating. Hormonal sensitivity varies from person to person. If you have previously experienced significant PMS or mood-related symptoms with hormonal treatments, this should be discussed during your consultation.
After stopping norethisterone tablets, your period usually begins within two to three days.
Your next cycle may be slightly different in timing or flow, but most women return to their normal pattern within one cycle. If your period does not return as expected, you should seek medical advice.
Your menstrual cycle is personal. Whether you are planning a holiday, preparing for a wedding, or observing an important religious event, you deserve reliable and respectful medical support.
At The Care Pharmacy, we are proud to champion women’s health with regulated online access to norethisterone tablets, delivered discreetly and supported by qualified UK professionals.
