Drug Type: Antibiotic


Florfenicol is a broad-spectrum, primarily bacteriostatic, antibiotic with a similar mechanism of action as chloramphenicol (inhibition of protein synthesis). Florfenicol is effective against a number of many Gram-negative and Gram-positive organisms, including certain chloramphenicol-resistant strains of Escherichia coli, Salmonella typhimurium and Staphylococcus aureus. Florfenicol is used most often to treat respiratory disease.

Caution: Recent research shows that florfenicol causes kidney damage to broilers and is toxic to developing chick embryos at around day 5 of incubation.
