`We also refer to our letter dated July 12, 2024, notifying you, under Section 505(o)(4) of
`the FDCA, of new safety information that we have determined should be included in the
`labeling for nonsteroidal anti-inflammatory drugs (NSAIDs). This information pertains to

`fixed drug eruption (GBFDE).

`changes in pending “Changes Being Effected” (CBE) supplements, as well as annual
