Indications

  • Gram-negative infections.
  • Some staphylococcal Staphylococcus spp and streptococcal Streptococcus spp (fecalis) infections.
    All obligate anaerobic bacteria and many haemolytic streptococci are resistant.
  • As neomycin is extremely nephrotoxic and ototoxic it is:
    • Primarily used topically for infections of skin, ear or mucus membranes, or orally to reduce intestinal bacterial population in treating hepatic encephalopathy and before intestinal surgery.
    • Non-specific bacterial enteritides - often in combination with antimuscarinic agents.
    • Treatment of hepatic encephalopathy (coma) together with dietary protein reduction and lactulose Lactulose : 20 mg/kg PO QID.
    • To reduce bacterial flora before elective colorectal surgery (along with appropriate bowel evacuation): 500 mg-1 g (with an identical dose of erythromycin Erythromycin base) 19 hours, 18 hours and 9 hours before surgery.
    This dosage regimen is derived from human data. Differences in gastrointestinal (GI) transit times may alter the dosing schedule in dogs.
