For the treatment and control of colibacillosis (bacterial enteritis) caused by Escherichia coli susceptible to neomycin sulfate in cattle (excluding veal calves), swine, sheep and goats.

Dosage and Administration

Administer to cattle (excluding veal calves), swine, sheep and goats at a dose of 10 mg neomycin sulfate per pound of body weight in divided doses for a maximum of 14 days.

Dosage Schedule for Treatment of Colibacillosis:

Pounds of Body Weight

25 lb

1.2 mL (1/4 tsp*)

50 lb

Neomycin Oral Solution may be given undiluted or diluted with water.

Herd Treatment: Each 473.1 mL (1 Pt) will treat 9464 pounds of body weight. Each 3.785 L (1 Gal) will treat 75,700 pounds of body weight. Therefore, estimate the total number of pounds of body weight of the animals to be treated and administer 29.5 mL (1 Fl Oz) for 591.5 pounds. The product should be added to the amount of drinking water estimated to be consumed in 12-24 hours. Provide medicated water as the sole source of water each day until consumed, followed by non-medicated water as required. Fresh medicated water should be prepared each day.

Individual Animal Treatment: To provide 10 mg neomycin sulfate per pound of body weight, mix 5 mL (1 tsp*) in water or milk for each 100 pounds of body weight. Administer daily either as a drench in divided dosages or in the drinking water to be consumed in 12-24 hours.

Neomycin Oral Solution Caution

To administer the stated dosage, 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 persist after using this preparation for 2 or 3 days, consult a veterinarian. 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 poor absorption from the gastrointestinal tract.

Important: Treatment should continue 24 to 48 hours beyond remission of disease symptoms, but not to exceed a total of 14 consecutive days. Animals not drinking or eating should be treated individually by drench.
