BENZOAK VET® (benzocaine)

INAD#
11-740

BENZOAK VET® is a liquid containing 20% benzocaine that is applied as an immersion bath treatment. BENZOAK VET® is only available for purchase through Pharma Production AS/Riverence Brood LLC. The primary goal of field studies conducted under INAD #11-740 is to evaluate the efficacy of BENZOAK VET® for use as an anesthetic/sedative in all freshwater finfish, freshwater prawn, and all saltwater finfish. Fish may be treated between 10 – 150 milligram (mg) benzocaine per L for up to 15 minutes. Treatment duration will vary dependent upon species and water temperature. BENZOAK VET® should be applied as a single treatment event. A 72-hour investigational withdrawal period is required for doses up to 100 mg/L and 96-hour for doses between 101 to 150 mg/L, and if other INADs that are authorized by the FDA are used with BENZOAK VET®, then the longest withdrawal time needs to be followed. To participate in the INAD Program for BENZOAK VET® visit thedata collecting site.

Please read the Study Protocol prior to any treatments. It contains the protocol, SDS, and a copy of the forms to be used as a guide for collecting data that will be entered into the online INAD database. The FDA authorization letters for this INAD are currently only available by emailing Bonnie Johnson.
