1. Uses of Mefenamic Acid
Mefenamic acid may act on the prostaglandin production in the body, which are chemical substances implicated in both pain and inflammation. This action mechanism makes it suitable for various applications, such as
Pain: The drug is applicable in mild to moderate states of pain. Mefenamic acid is commonly prescribed for dental pain, muscular pain, and back pain.
Menstrual Pain: This drug is often used by many people to treat dysmenorrhea, which is painful menstrual cramps. Its anti-inflammatory action diminishes the degree of cramps.
Arthritis Symptoms: It may be useful in alleviating symptoms of rheumatoid arthritis and osteoarthritis by mitigating the pain and inflammation experienced by patients, though often not as a first-line treatment.
Headaches: Some persons use mefenamic acid in the management of tension headaches or mild migraine headaches; its effectiveness is however more variable for this indication.
2. Preparations of Mefenamic Acid
Mefenamic acid exists in several preparations to meet different patient needs:
Tablets and Capsules: The preferred preparations of mefenamic acid are given in dosages of either 250 mg or 500 mg, which come in either tablets or capsules. These are administered orally with meals to reduce the chance of gastric irritation.
Oral Suspension: For patients who may have problems taking tablets, an oral suspension preparation of mefenamic acid may be offered. This is handy, especially for pediatric and geriatric patients.
Topical Gels and Creams: Mefenamic acid can in some cases be prepared in topical formulations. They are applied topically as analgesics, though not so frequently applied.
The dose to be given normally depends on the intensity of the pain, age, weight, and general state of health. It is usually prescribed for a short period, like 7 days or less, unless otherwise advised by a healthcare provider.

Anti-Inflammatory Activity: Its anti-inflammatory effect makes it useful for inflammatory pain, such as arthritis.
4. Disadvantages of Mefenamic Acid
Despite being effective, mefenamic acid has potential disadvantages and risks that include:
Gastrointestinal Side Effects: Mefenamic acid is known to cause gastrointestinal irritation, resulting in a number of symptoms like abdominal pain, indigestion, or peptic ulcers. This should be taken with food to reduce the chance for side effects, but prolonged therapy is still not recommended due to the danger of gastrointestinal bleeding.
Kidney and liver problems: The use of mefenamic acid for extended periods is likely to put strain on the kidneys and the liver, like all other NSAIDs. Patients with predisposed medical conditions involving the kidney or liver must avoid this medication, or if their use is necessary, they will have to be under strict observation.
Cardiovascular Events Risk: Patients on high doses of NSAIDs, such as mefenamic acid, might face a high risk of having a heart attack and stroke, mainly when taken over an extended period.
Allergic Reactions: Some patients react with allergies, from mild rashes to severe reactions of shortness of breath. Patients allergic to aspirin or other NSAIDs should not use mefenamic acid.
5. Dosage and Administration
Mefenamic acid is usually taken as part of the following regimen:
Adults: A common dosage involves 250 mg to 500 mg every three hours. Again, any dosage depends on the intensity of pain and tolerance in the patient’s body.
Pediatrics: The dose of mefenamic acid for children differs and is commonly given on the basis of body weight and age. Pediatric dosing must always be supervised by a doctor.
Schedule Duration: Mefenamic acid should be given with food or milk to decrease gastrointestinal adverse effects, and its use is generally restricted only for short duration, up to five to seven days.
6. Precautions and Contraindications
The administration of mefenamic acid requires some precautions as follows:
Alcohol Avoidance: The use of alcohol is likely to increase the risk for bleeding in the digestive system when mixed with an NSAID such as mefenamic acid.
Pregnancy and Lactation: Pregnant and nursing mothers should only use this medication if recommended by a physician, as the medication can cause some harm to the fetus or baby.
Medication Interactions: Mefenamic acid may interact with other medications such as blood thinners, other NSAIDs, and specific antidepressants. This medication should be communicated to a patient’s physician with all the medicines he/she is taking presently.
Monitoring: The patient on long-term NSAIDs, particularly at higher doses, should be followed up regularly regarding kidney, liver, and heart functions.
