What is Primolut N?

Primolut N is a medication that’s used to mitigate negative side effects from your period. These include heavy or irregular periods, pain, and premenstrual syndrome (PMS). It can also be used to delay your period if you have a special event planned.

Heavy and painful periods are inconvenient at best. In some cases, they can prevent you from participating in activities that are part of your routine. They are caused by hormone imbalances, fibroids, cancer, and other conditions.

How does Primolut N work?

The active ingredient in Primolut N is norethisterone, which is a derivative of the hormone progesterone. It’s a synthetic form of a hormone that is a normal part of the menstrual cycle.

Norethisterone can provide relief from heavy and painful periods because it mimics the naturally occurring progesterone in your body. It can prevent your uterine lining from building up as much each month, reducing the amount your body needs to expel each month during your period. As a result, it also decreases the need for the muscle contractions that cause pain when they loosen the thickened endometrium in your uterus during your period.

What doses of Primolut N are there?

Primolut N is available in only one dose containing 5 mg of norethisterone BP. If it isn’t providing adequate relief for your period symptoms, you should sign in to your account and send our clinician a message. They may suggest another treatment that will work better for you.

How to take Primolut N

Sticking to your Primolut N treatment plan is simple and straightforward. You will need to follow instructions based on whether you’re taking it to treat heavy periods or delay your period.

For heavy bleeding

  • Take one Primolut N pill two or three times a day for days 19 through 26 of your menstrual cycle.
  • You don’t need to take it with food, but you should drink water when you swallow it.
  • Don’t chew, crush, or break Primolut N.

To delay your period

  • Start taking Primolut N three days before your period is supposed to start.
  • Swallow one whole pill three times a day for up to 14 days.
  • Don’t tamper with Primolut N by breaking or cutting it.
  • Your period should start two or three days after you stop taking Primolut N.

How long does it take Primolut N to work?

You must plan in advance for Primolut N to be effective. If you’re using it for heavy periods, it has to be taken during days 19-26 of your period. And if you need to delay your period, you have to start taking it three days before your regular period. After you finish taking Primolut N, your period should start in about two to three days.

What should I do if I make a mistake when taking Primolut N?

Most of the time, making a mistake whilst taking Primolut N isn’t a big deal. If you feel sick or have side effects after taking too much, speak to a clinician.

You shouldn’t worry if you miss a dose of Primolut N. Don’t take a double dose to make up for it. Simply take your next dose on time and you should be fine.

FAQ: Primolut N

Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.

Is Primolut N similar to any other treatments?

Primolut N is similar to many other medications. The active ingredient, norethisterone, is also in other branded and generic medications. The only difference is the company that makes it and the prices. Other than that, these medications should have the same therapeutic effects unless they also contain other active ingredients.

How is Primolut N different from other treatments?

There are many different medications that can be used to treat heavy and painful periods. While some medications are used to treat pain or heavy bleeding from periods, there are a lot that can provide relief for both like Primolut N. Many of these medications have the same or similar active ingredients.

Other medications often contain a slightly different derivative of progesterone than Primolut N called medroxyprogesterone. If you’re not sure which treatment is best to treat your heavy or painful periods, our clinician can advise you on the right medications for you.

Which version of norethisterone should I use?

Your personal preference will dictate which kind of norethisterone you take. Treatments for heavy periods that contain the active ingredient norethisterone will work in the same way.

Do I need a prescription for Primolut N?

Hormone treatments like Primolut N are not available over the counter. It’s a prescription only treatment because it carries a risk of blood clots and other life threatening conditions, so our clinician will need to make sure it’s safe and suitable for you to use in the first instance.

Why should I buy Primolut N online with Treated?

We not only provide you with treatment. We provide you with ongoing support too. So once you’ve chosen your medication from the options recommended by our clinical team, our clinicians will reach out to you regularly to find out how you’re getting on with your treatment.
