Period Delay Tablets

How do period-delay tablets work?

Period delay tablets containing Norethisterone 5mg can be taken three times each day to postpone periods. Start taking the tablets at least three days before your period begins and continue for as long as you need them. After quitting the medications, a menstrual bleed usually begins 2-3 days later, and may last longer.

During the menstrual cycle, the hormone balance shifts. A menstruation (the shedding of the uterine lining) will be postponed when using Norethisterone tablets.

Norethisterone should not be used to delay periods in women who are currently taking a contraceptive pill. The NHS page How can I postpone my period? has more information about postponing periods while on contraceptive tablets.

How long is it safe to delay your period?

Delaying your period for a short period (up to a few days or a week) using medications like norethisterone is generally considered safe for most women.

Ashcroft Pharmacy can supply Norethisterone tablets to last up to 17 days, with a maximum of 60 tablets available. If the delay is smaller than 17 days, the tablets are taken for fewer days and fewer tablets are needed.

Taking period-delaying medications is just for occasional use and should not be asked more than once every three months (four times per year).

Consult your own doctor if you need to delay your period more regularly or for a longer amount of time. Period control can often be achieved by taking a hormonal contraceptive, with many contraceptives lowering or eliminating periods entirely.

However, it’s important to note that delaying your period for an extended period (longer than a few weeks) or doing it frequently is not recommended without medical advice

Patients must read the patient information pamphlets included with the tablets.

Interactions with other drugs

There are a few drugs that can cause Norethisterone to interact. This could reduce the effectiveness of either medicine. The checks are done through the online consultation.

Side effects that may occur

Norethisterone, like many drugs, can produce side effects, albeit they are usually minor. Side effects are covered in greater detail in the manufacturer's patient information leaflets, which are included in pharmaceutical packages.

Side effects of Norethisterone 5mg

Bloating, breast discomfort, and a decrease of libido are the most commonly reported side effects. If you use Norethisterone for a long time instead of a short time to delay periods, you're more likely to get side effects.

Fluid retention is a side effect of Norethisterone for certain women, which can exacerbate pre-existing migraine, epilepsy, blood pressure, and asthma.

Fluid Retention and Period Delay Pills

Fluid retention, or edema, is a common side effect of progestogen-based period delay tablets, such as Provera and norethisterone.

In simple terms, fluid retention means your body is holding onto extra water. You might notice swelling in your legs, ankles, or fingers, and you may feel bloated.

Period delay pills can cause fluid retention, which can worsen certain health conditions. If you have:

• Epilepsy
• Migraine
• Asthma
• Heart disease
• Kidney issues

Fluid buildup could be harmful. If symptoms worsen, stop the medication and consult your doctor. Ashcroft Pharmacy cannot prescribe these pills for these conditions.

Can you use them again if you have problems?

If you experience worsening of any of these conditions while taking Provera or norethisterone, it's crucial to stop taking them and inform your doctor. It's very unlikely you'll be advised to take them again. The risks outweigh the benefits. You should discuss alternative period delay tablets with your GP.

Extremely uncommon sensitivity reactions

Provera and norethisterone might induce serious allergic reactions in certain people. The sudden onset of any or all of the following conditions need immediate medical attention (dial 999 in the UK):

• Itchy rash on the skin.
• Hands and feet are swollen.
• Swelling of the mouth or face.
• Feeling a little lightheaded.
• Breathing problems.
• Wheezing.

Blood clots are a possibility (Venous Thromboembolism)

A blood clot in the veins of the legs, the lungs, or other parts of the body is a modest risk for all women. If you use Norethisterone, your chances of getting a clot are slightly enhanced.

If any of the following apply, Ashcroft Pharmacy cannot give Norethisterone since they raise the risk of blood clots:

• Obese or very overweight.
• There has been a previous blood clot in the veins or lungs.
• Blood clots have occurred in relatives.
• Long durations of immobility, such as after an operation or during a long-haul flight (6+ hours).
• Following a major injury or surgery.
• Repeated miscarriages in the past.

The longer the cycle is extended, minor spotting or bleeding may occur in roughly 10% of women.
