                                The United States Food and Drug Administration (FDA) has established specific limitations for the use of D&C Red No. 33, a color additive often confused with the recently banned food dye FD&C Red No. 3. While Red 33 is not approved for food use, it has defined parameters for its inclusion in certain ingested pharmaceuticals.
