Period pain

Period pain is something which almost every woman will encounter at some point in their lives. Some may even experience it on a frequent basis. While many women will normally endure small amounts of pain during menstruation, sometimes this pain will be more intense and uncomfortable than usual.

During menstruation, the female reproductive system undertakes various processes in order to get ready for pregnancy. One of these involves the thickening and shedding of the lining of the uterus. A fertilised egg latches onto this lining and begins its development into an embryo. However, when fertilisation does not take place, the lining of the uterus sheds and is discharged via menstrual bleeding.

Muscular movements around the womb are required for this shedding to take place, and these can cause feelings of pain and discomfort.

Heavy periods

Heavy periods is the name given to overly-abundant menstrual bleeding. It can sometimes be the result of an underlying health issue, such as hypothyroidism or polycystic ovary syndrome.

However, half of women with heavy periods will have no specific cause. This is sometimes known as dysfunctional uterine bleeding. While those instances of heavy periods that aren’t caused by an illness will often not be a health concern, they can still be frustrating and very uncomfortable to endure.

As explained above, during menstruation, the lining of the uterus becomes thicker, so it is ready for a fertilised egg to implant and develop. If implantation doesn’t occur, the wall sheds, and is evacuated during menstruation.

In those with heavy periods, this evacuation will be more substantial. Defining how much bleeding is too much isn’t straightforward, as everyone is different and there is no specific amount of how much someone should lose. Women will usually be able to tell when they’re losing more than usual, but signs of heavy periods may include: using more sanitary products than you normally would; or blood leaking through to clothes.

There are treatment options available to those looking to reduce the severity of menstrual bleeding. If it is the result of another condition, such as polycystic ovary syndrome (PCOS) or hypothyroidism, then the primary condition will require attention from a doctor. But for those whose bleeding is not due to any other ailment, then hormonal treatment may be issued to help reduce the level of blood loss.

How do treatments work?

In the body, the particular process involving the buildup and discharge of the womb lining is managed by a hormone called progesterone. When the presence of this hormone drops, the uterine lining builds up and sheds (thus causing period pain or heavy bleeding in those affected).

Both Primolut N, which is a medicine made by Bayer, and Utovlan, by Pfizer, temper this process by supplementing levels of this hormone with norethisterone which is a synthetic version of progesterone. This results in the uterine lining developing and being released in more manageable amounts, so that less exertion is required on the part of the muscles in the womb, and as a result, less pain is felt; and heavy menstrual bleeding is lessened.

Heavy periods and period pain are common. However, you should talk to your GP if you are having period pain, or if you think your periods are heavier than normal. They may need to ask you some questions and conduct tests to identify whether there is an underlying issue causing the problem. Where appropriate, they can initiate a prescription for treatment where required.

Types of Treatment

If you are experiencing new symptoms of period pain or heavy menstrual bleeding, or have noticed a change in your usual symptoms, you should see your GP to rule out any potential causes of this.

How heavy or painful periods are treated will depend on what their cause is.

Some conditions, such as polycystic ovary syndrome (PCOS) and hypothyroidism, can lead to heavy menstrual bleeding. Treating these conditions may reduce the presence of excessive bleeding.

However, it is common for heavy periods to occur with no specific cause.

There are several treatments available for heavy or painful periods. Which you are issued may depend on the other treatments you are currently taking.

Your GP may be able to help you manage period pain with the contraceptive pill, if it is suitable.

However in cases where this does not prove sufficient, they may suggest a treatment specifically for the management of heavy periods and period pain.

Utovlan and Primolut N are only available to buy on prescription, and both contain a synthetic hormone called norethisterone.

The treatments function by temporarily altering the way the body manages the lining of the uterine wall, but cannot be taken in addition to the contraceptive pill.

If you haven’t used treatment for heavy or painful periods before, you should speak to your GP about the available options.

How do they work?

The process of menstruation is managed in the body by progesterone. When levels of the hormone drop, the lining of the uterine wall builds up and subsequently sheds if fertilisation does not occur. In Primolut N and Utovlan, the artificial hormone keeps this growth and exuviation under control, and reduces heavy menstrual bleeding, as well as pain and discomfort.

What are the side effects?

Utovlan and Primolut N contain the same ingredient, but the side effects they induce may be slightly different. Common side effects across both include headache, reduced menstrual bleeding and ‘spotting’ between periods.

View the respective product pages for more information.

Can I take them with other medications?

Be aware that these medications may interact with the efficacy of other products. Let your doctor know if you are using any other treatments during consultation.
