What the FDA Data Shows for cholecalciferol

The FDA label for cholecalciferol (sold under brand names such as Vitamin D3) classifies it as an over-the-counter product in the Vitamin D3 Supplement class. PNV-DHA is used to help people who don't get enough nutrients 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. Voluntary reports accumulate over the lifetime of a drug and reflect wide-ranging clinical use. Interaction data is drawn directly from FDA-approved prescribing information. 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 4 recall records on file), and patent information further shape supply and switching decisions.
