How to Read This mefenamic acid vs meloxicam Comparison
mefenamic acid is classified in the Nonsteroidal Anti-Inflammatory Drug (NSAID) drug class, while meloxicam sits within the Nonsteroidal Anti-Inflammatory Drug (NSAID) class. Because both drugs share the same classification, they are often considered interchangeable in theory, but clinical outcomes rarely track that cleanly. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, mefenamic acid has 1,155 submissions while meloxicam has 20,600. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to both of these drugs are nsaids that work in the same way, so taking them together increases the risk of stomach issues without helping more with pain.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
