What is Norethisterone?

Norethisterone 5mg is an easy-to-take medication that can help you to safely delay your period by up to two weeks; the majority of women who are not already using oral contraceptives will be able to use Norethisterone at times when they are looking to do so.

Norethisterone is actually the active ingredient in the medication and is a synthetic version of the hormone, progestogen. This synthetic hormone imitates the effects that natural hormones have on your body and, in doing so, it can maintain hormone levels and prevent the normal decrease in progestogen levels that cause the period.

During a woman's menstruation cycle, the lining of the uterus begins to grow thicker in preparation or an egg to develop there. At the end of the cycle, this excess lining is discharged in what is commonly referred to as the period. Norethisterone is essentially used to delay this process.

What are the benefits of Norethisterone?

As well as being an effective method of period prevention, Norethisterone 5mg can also be used to help some other menstrual-related concerns like:

  • Heavy bleeding
  • Pain during periods
  • Pre-menstrual symptoms
  • Unusual uterine bleeding not related to a period
  • Endometriosis

Of course though, its main benefit comes in the prevention that it can provide. Effective and easy-to-use, Norethisterone is a medication that can offer a great deal of comfort for someone who is worried that a special event, a holiday for example, might be ruined or negatively affected by the symptoms of their period. Another important factor to be considered is that using this medication to delay your period will in most cases not lead to an unusually heavy period when the effects of the ingredients wear off.

Who can use Norethisterone?

Norethisterone can be used by women that are over the age of 18 and who want to delay their period. Certain treatments and conditions do prevent you from being safe to use the treatment though:

  • Combined contraceptives
  • Deep vein thrombosis
  • Liver problems
  • Cardiovascular problems

Although it may not always prevent you from using this treatment, it is vital that, if there are any other medical concerns that affect you, you let your doctor know during the online consultation. It is important to recognise that you are unable to use this medication if you are already using a combined contraceptive.

Are there any side effects?

The occurrence of side effects whilst using Norethisterone is quite rare, however as with most prescription medication, there is always a slight risk. Some of the most commonly reported side effects with Norethisterone include:

  • Stomach aches
  • Itching
  • Rashes
  • Nausea
  • Headaches

In very rare cases, users may also experience more severe side effects like facial swelling and wheezing, however this is incredibly uncommon and is more likely to be the result of allergic reaction than an adverse effect caused by the drug as a whole. If you have any allergies that may affect the efficacy of the medication then it is important you mention them during the consultation and, likewise, if you do experience any side effect persistently then you should contact a doctor.

How do I use Norethisterone?

Available in a tablet form, Norethisterone is an incredibly easy-to-take option for women who are looking to delay their period. For a simple set of instructions on how to use this medication, take a look below.

  • Take first tablet three days before period
  • Then take three tablets each day until you want your period to return
  • Once you discontinue using this medication, should experience your period within a few days
  • The period will be just as it normally is
