Additional Safety Information

  • Use of more than one product containing neomycin or failure to follow withdrawal times may result in illegal drug residues.
  • Not for use in liquid supplements.
  • The concentration of neomycin required in medicated water must be adjusted to compensate for variation in age and weight of animal, the nature and severity of disease signs, and environmental temperature and humidity, each of which affects water consumption.
  • If symptoms such as fever, depression, or going off feed develop, oral neomycin is not indicated as the sole treatment since systemic levels of neomycin are not obtained due to low absorption from the gastrointestinal tract.
