What the FDA Data Shows for pyridoxine
The FDA label for pyridoxine (sold under brand names such as Vitamin B6) classifies it as an over-the-counter product in the Vitamin B6 Supplement class. PNV-DHA is used to help people who don't get enough vitamins and minerals from their diet. Labeling covers dosing, contraindications, and monitoring requirements derived from clinical trials.
Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. For this drug, FAERS contains 3,060 voluntary reports. The database also lists 1 documented drug interaction derived from FDA labeling, with the top-flagged interaction rated minor severity. Acquisition-cost data is surveyed weekly by CMS and updated as manufacturers report changes.
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 3 recall records on file), and patent information further shape supply and switching decisions.
