Important Safety Information

Using NAROPIN beyond recommended doses to increase motor block or duration of sensory block may negate its favorable cardiovascular advantages, in the event that an inadvertent intravascular injection occurs.
Like all amide-type local anesthetics, NAROPIN may be associated with adverse reactions. In clinical trials, side effects were mild and transient and may reflect the procedures, patient health status, and/or other medications used. Adverse events reported at a rate of ≥5%: hypotension, nausea, vomiting, bradycardia, fever, pain, postoperative complications, anemia, paresthesia, headache, pruritus, and back pain.

New Safety Information

There have been adverse event reports of chondrolysis in patients receiving intra-articular infusions of local anesthetics following arthroscopic and other surgical procedures. NAROPIN is not approved for this use.
