Neomycin Liquid may be given undiluted or diluted with water.

Herd Treatment: Each bottle will treat 9,600 pounds body weight. Therefore, estimate the total number of pounds body weight of the animals to be treated and administer one (1) fluid ounce for each 600 pounds. The product should be added to the amount of drinking water 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 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 one(1) teaspoon in water or milk for each 100 pounds body weight. Administer daily either as a drench in divided doses or in the drinking water to be consumed in 12-24 hours.

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 low 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.


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.


Not for human use. Keep out of reach of children. Discontinue treatment prior to slaughter by at least the number of days listed below for appropriate species:

         Cattle ....................... 1 day

         Sheep ...................... 2 days

         Swine and Goats ....... 3 days
