Does the full prescribing information or the brief summary type have to be any particular size?
No, but the regulations specify size in sections 201.10(g)(2) and 202.1(b)(2) which state: “The established name shall be in printed letters that are at least half as large as the letters comprising the proprietary name or designation with which it is joined, and the established name shall have a prominence commensurate with the prominence with which such proprietary name or designation appears, taking into account all pertinent factors, including typography, layout, contrast and other printing features.”
