Always consult a veterinary physician or animal care specialist before using procaine penicillin G and neomycin sulfate injections.
Indications and Usage
Bactracillin G is indicated for treatment of bacterial pneumonia (shipping fever) caused by Pasteurella multocida in cattle and sheep, erysipelas caused by Erysipelothrix rhusiopathiae in swine, and strangles caused by Streptococcus equi in horses.
It is also indicated in the treatment of acute and sub-acute bovine mastitis in milking cows, accompanied by pain and inflammation caused by bacteria sensitive to penicillin, streptomycin and neomycin therapy.
- Hypersensitivity to penicillin and/or procaine;
- Administration to animals with a seriously impaired renal function;
- Concurrent administration of tetracyclins, chloramphenicol, macrolides and lincosamides.
Do not administer by the intravenous route.
Administration and Dosage
Administration should be by deep intramuscular injection in all species.
Usual dosage is as follows: 5mg of procaine penicillin G and neomycin sulfate per kg body weight for cattle, pigs and horses and 10mg of procaine penicillin G and neomycin sulfate per kg body weight in small animals (intramuscularly). Procaine penicillin G and neomycin sulfate injections shouldn’t be administered if any hypersensitivity is discovered.
Maximum dose for cattle and horses is 25 ml and for pigs is 6 ml.
The daily dose of penicillin is 3,000 units per 45 kg of body weight. Continue daily treatment until recovery is apparent and for at least one day after symptoms disappear, usually in two to three days. Treatment should not exceed four consecutive days.
Refer to an animal care specialist for guidelines on dosage. Do not exceed what they advise, and complete the full treatment, as stopping early can result in a recurrence or worsening of the problem.
- Hypersensitivity to penicillins may lead to cross-sensitivity to cephalosporins and vice versa;
- If the animals develop the symptoms such as skin rash or any other skin allergies, seek medical advice with a veterinarian;
- Swelling of the face, lips or eyes or difficult breathing are more serious symptoms and require urgent medical attention.
