*Not Applicable.

†The dose for a major nerve block must be adjusted according to site of administration and patient status. Supraclavicular brachial plexus block may be associated with a higher frequency of serious adverse reactions, regardless of the local anesthetic used (SEE PRECAUTIONS).

‡Median dose 21 mg per hour was administered by continuous infusion or by incremental injections (top-ups) over a median delivery time of 5.5 hours.

§Cumulative doses up to 770 mg of NAROPIN over 24 hours (intraoperative block plus postoperative infusion). Continuous epidural infusion at rates up to 28 mg per hour for 72 hours have been well tolerated in adults; ie, 2016 mg plus surgical dose of approximately 100–150 mg as top-up.
