What is Mefenamic Acid?

We are often asked “what is mefenamic acid?”

Mefenamic Acid is a prescription drug. It’s only available as an oral capsule.

Mefenamic Acid is available as the brand name Ponstel or it can come as a generic drug. The generic version usually costs less than the branded one, although in some cases the branded version may not have certain strengths or forms.

It’s called a nonsteroidal anti-inflammatory drug, a specific class of drug, also known as NSAIDs. They help to reduce pain, inflammation and fever.

By blocking a naturally occurring chemical called cyclo-oxygenase enzymes, the body produces fewer chemicals called prostaglandins. Some of these prostaglandins are produced at sites of injury and can cause pain and inflammation. So by blocking these from producing, Mefenamic Acid helps relieve pain and inflammation.

For a more complete answer on ‘What is Mefenamic Acid?’ talk with your doctor or consult the patient information leaflet.

Alternative to Mefenamic Acid Period Pain Relief

Period Pain

Period pain is common and a normal part of your menstrual cycle. Most women experience it at some point in their lives.

It’s usually felt as painful muscle cramps in the tummy, which can spread to the back and thighs.

The pain sometimes comes in intense spasms, while at other times it may be dull but more constant.

What causes period pain?

Period pain occurs when the muscular wall of the womb tightens (contracts).
During your period, the wall of the womb starts to contract more vigorously to encourage the womb lining to shed away as part of your monthly period.

When the muscular wall of the womb contracts, it compresses the blood vessels lining your womb. This temporarily cuts off the blood supply – and hence oxygen supply – to your womb. Without oxygen, the tissues in your womb release chemicals that trigger pain.

While your body is releasing these pain-triggering chemicals, it’s also producing other chemicals called prostaglandins. These encourage the womb muscles to contract more, further increasing the level of pain.

Period pain caused by a condition

Less commonly, period pain can be caused by an underlying medical condition. Doctors sometimes call this secondary dysmenorrhoea.

Period pain linked to an underlying condition tends to affect older women. Women aged 30 to 45 are most commonly affected.

Conditions that can cause period pain include:

endometriosis – where cells that normally line the womb start to grow in other places, such as in the fallopian tubes and ovaries; these cells can cause intense pain when they shed and fall away
fibroids – non-cancerous tumours that can grow in the womb and can make your periods heavy and painful
pelvic inflammatory disease – where your womb, fallopian tubes and ovaries become infected with bacteria, causing them to become severely inflamed
adenomyosis – where the tissue that normally lines the womb starts to grow within the muscular womb wall, making your periods particularly painful

Side Effects

Like all medicines Mefenamic Acid can cause side effects, although not everybody gets them.
All medicines can cause allergic reactions although serious

allergic reactions are rare. Any sudden wheeziness, difficulty in breathing, swelling of the eyelids, face or lips, rash or itching

episodes of peptic ulcer, stomach bleeding or perforation.
