Final answer:
The list of food dyes in medication is found in the inactive ingredients section of the package insert, which is essential to check for patients with allergies to specific dyes.

The list of food dyes in medication can be found in the inactive ingredients section of the package insert or labeling. This section provides detailed information about all the non-medicinal ingredients, including colorants such as food dyes that might cause allergic reactions in some patients. In the case of Taylor, who is allergic to red dye and penicillin, careful examination of this section is crucial in order to ensure that the antibiotic prescribed does not contain any red dye and is not a penicillin-derived medication, as these could lead to a potential allergic reaction.
