What is Mefenamic Acid Used For?
Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID) used to treat mild to moderate pain [1]. It is commonly prescribed for menstrual pain (dysmenorrhea) and other inflammatory conditions [2].
How Does Mefenamic Acid Work?
Mefenamic acid functions by inhibiting the production of prostaglandins, which are chemicals in the body that contribute to pain, inflammation, and fever [1][2].
What is the Average Price of Mefenamic Acid?
The price of mefenamic acid can vary depending on the dosage, quantity, and pharmacy [3]. For example, a 30-count bottle of 500mg tablets can range from approximately $8 to $16 at different online pharmacies [3]. Generic versions are generally more affordable than brand-name medications [3].
Are There Different Forms of Mefenamic Acid Available?
Mefenamic acid is typically available in oral dosage forms, most commonly as tablets [1].
When Does Mefenamic Acid Go Off Patent?
Mefenamic acid has been available as a generic medication for many years, indicating its patents have long expired [4]. New patent filings related to specific formulations or delivery methods could exist, but the compound itself is off-patent [4].

Multiple pharmaceutical companies produce generic mefenamic acid. Brand names associated with mefenamic acid have included Ponstel [1].
What Are the Potential Side Effects of Mefenamic Acid?
Common side effects of mefenamic acid can include stomach upset, nausea, vomiting, heartburn, diarrhea, and dizziness [1]. More serious side effects, though less common, can include gastrointestinal bleeding, kidney problems, and allergic reactions [1].
How Does Mefenamic Acid Compare to Other Pain Relievers?
As an NSAID, mefenamic acid works similarly to ibuprofen and naproxen in reducing pain and inflammation [2]. However, individual responses to these medications can differ. For very mild pain, over-the-counter options like acetaminophen may also be considered, though it does not have the same anti-inflammatory properties [5].
What Should I Consider Before Taking Mefenamic Acid?
Individuals with a history of stomach ulcers, bleeding disorders, kidney disease, or heart conditions should consult a healthcare professional before taking mefenamic acid [1]. It is also important to discuss any other medications being taken to avoid potential interactions [1].
