Mefenamic acid is a prescription painkiller widely used for period pain, muscle cramps and heavy bleeding during periods.
Mefenamic acid works by reducing the hormones that cause inflammation and pain in the body and is not just prescribed for period pains; it is also used to treat other painful conditions such as arthritis and for pain control after surgical procedures. Mefenamic acid works by blocking chemicals made by the body called cyclo-oxygenase enzymes (COX) which in turn help to make other chemicals called prostaglandins. Period pains are caused by the production of prostaglandins in the lining of the womb and so taking Mefenamic acid can help to control the discomfort and pain experienced by some women by relieving their symptoms. It also reduces blood loss in women who suffer from heavy menstrual bleeding as prostaglandin production is known to be at a higher level in women who suffer from heavy periods.
Most women experience period pain at some time in their lives. Described in medical terminology as 'dysmenorrhoea', period pain is usually defined as muscle cramps in the lower abdomen, which can range from mild through to intense and painful, sometimes spreading to the thighs and around the body to the lower back. The pain varies from a dull, nagging ache or sensitivity to severe spasms which are caused by the muscular wall of the womb as it contracts and presses against adjacent blood vessels, interrupting the oxygen supply to the womb and thus triggering pain. Most period pains usually occur as the bleeding starts and may last for two or three days.
Prostaglandins are also produced by the body in response to certain diseases and conditions and even injury all of which may cause pain, swelling and inflammation. Therefore Mefenamic acid has a role to play in effectively controlling symptoms in other situations and it may also work in preventing the action of prostaglandins even after they have been produced.
Mefenamic acid comes in tablet form and as with other anti-inflammatory medication, it is recommended that you take it either with or after food to avoid irritating the lining of the stomach.
Mefenamic acid is usually taken three times a day at mealtimes as this is one way to ensure that you remember to take it and that the dosages are fairly evenly spaced.
If you forget to take a dose at your usual time, then take it as soon as you remember, making sure it is not on an empty stomach. If it is nearly time for your next tablet then don't double up, just leave out the missed tablet and carry on with your dosage as normal. Do not take two tablets to make up for the missed dose.
