Mefenamic Acid for Pain Relief
Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID) used to treat mild to moderate pain [1]. It is available by prescription [2].
How Does Mefenamic Acid Work?
Mefenamic acid functions by inhibiting the production of prostaglandins, which are hormone-like substances that contribute to inflammation, pain, and fever [1]. By reducing prostaglandin synthesis, mefenamic acid alleviates these symptoms [1].
What Kind of Pain is Mefenamic Acid Used For?
This medication is primarily prescribed for the relief of pain associated with conditions such as:
* Menstrual pain (dysmenorrhea) [3]
* Rheumatoid arthritis [1]
* Osteoarthritis [1]
It is considered effective for acute pain conditions [2].
What Are the Potential Side Effects of Mefenamic Acid?
Like other NSAIDs, mefenamic acid can cause side effects. Common side effects may include:
* Gastrointestinal issues such as stomach pain, nausea, diarrhea, and constipation [2]
* Dizziness or drowsiness [2]
* Headache [2]
More serious, though less common, side effects can include stomach ulcers, bleeding, kidney problems, and allergic reactions [2]. Individuals with a history of stomach problems or kidney disease should use this medication with caution [2].
Are There Alternatives to Mefenamic Acid for Pain?
Yes, other NSAIDs like ibuprofen and naproxen are also used for pain relief [4]. Acetaminophen is another common pain reliever that works differently and is often considered for individuals who cannot tolerate NSAIDs [4]. The choice of medication depends on the specific type and severity of pain, as well as individual patient factors and medical history [4].
