What the FDA Data Shows for ketorolac

The FDA label for ketorolac (sold under brand names such as Toradol) classifies it as a prescription-only medication in the Nonsteroidal Anti-Inflammatory Drug (NSAID) class. Ketorolac is used for short-term relief of moderate to severe pain. Official labeling lists 26 commonly reported side effects, including Stomach pain, Constipation or diarrhea, Upset stomach.

Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. Voluntary reports accumulate over the lifetime of a drug and reflect wide-ranging clinical use. The database also lists 3 documented drug interactions derived from FDA labeling, with the top-flagged interaction rated major severity. NADAC pricing from CMS shows a generic unit cost of $11.41.

Report counts do not establish causation — a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history (currently 4 recall records on file), and patent information further shape supply and switching decisions.
