Florfenicol (marketed by Schering-Plough Animal Health under the trade name Nuflor) is a fluorinated synthetic analog of thiamphenicol.[1]

In the United States, florfenicol is currently indicated for the treatment of bovine respiratory disease (BRD) associated with Mannheimia (Pasteurella) haemolytica, Pasteurella multocida, and Haemophilus somnus, for treatment of bovine interdigital phlegmon (foot rot, acute interdigital necrobacillosis, infectious pododermatitis) associated with Fusobacterium necrophorum and Bacteroides melaninogenicus.

The use of florfenicol in horses, and likely in other equids, typically causes diarrhea. This has been anecdotally reported to progress to lethal cases of acute colitis. Therefore, use of this antimicrobial in the equine patient should be limited to cases in which other, safer, options are not available. [2]

Contamination

Florfenicol was among the drug contaminants in a brand of supermarket eggs in Taiwan and Iran.[3]
