`Attention: Leslie Sands, M.S., R.A.C.

`
`Morristown, NJ 07960
`
`Dear Ms. Sands:
`
`Please refer to your Supplemental New Drug Application (sNDA) dated and received August 7,
`2015, submitted under section 505(b) of the Federal Food, Drug, and Cosmetic Act (FDCA) for
`Treximet (sumatriptan and naproxen sodium).
`
`We also refer to our letter dated July 9, 2015, notifying you, under Section 505(o)(4) of the
`FDCA, of new safety information that we believe should be included in the labeling for
`nonsteroidal anti-inflammatory drugs (NSAIDs). This information pertains to the risks of
`cardiovascular thrombotic events and heart failure and edema. In that letter, we also requested
`that you adopt the revised NSAID class template labeling, so as to furnish adequate information
`for the safe and effective use of Treximet.
`
`This supplemental new drug application provides for revisions to the labeling for Treximet,
`consistent with our July 9, 2015, letter.
`
`APPROVAL & LABELING
`
`We have completed our review of this supplemental application. It is approved, effective on the
`date of this letter, for use as recommended in the enclosed, agreed-upon labeling text.
`
`

`labeling unless we notify you otherwise.
