Ampicillin for injectable suspension has proved effective in the treatment of many infections previously beyond the spectrum of penicillin therapy. This drug is particularly indicated in the treatment of the following infections caused by susceptible strains of organisms:
Dogs and Cats-Respiratory Tract Infections: Upper respiratory infections, tonsillitis and bronchopneumonia due to hemolytic streptococci, Staphylococcus aureus, Escherichia coli, Proteus mirabilis, and Pasteurella spp.
Urinary Tract Infections due to Proteus mirabilis, Escherichia coli, Staphylococcus spp., hemolytic streptococci and Enterococcus spp.
Gastrointestinal Infections due to Enterococcus spp., Staphylococcus spp. and Escherichia coli.
Skin, Soft Tissue and Post-Surgical Infections: Abscesses, pustular dermatitis, cellulitis and infections of the anal gland, due to Escherichia coli, Proteus mirabilis, hemolytic streptococci, Staphylococcus spp. and Pasteurella spp.
Cattle and calves Including Non-Ruminating (Veal Calves)-Respiratory Tract Infections: Bacterial pneumonia (shipping fever, calf pneumonia and bovine pneumonia) caused by Aerobacter spp., Klebsiella spp., Staphylococcus spp., Streptococcus spp., Pasteurella multocida and E.coli susceptible to aompicillin trihydrate.
The dosage of ampicillin of injectable suspension will vary accordign to the animal being treated, the severity of the infection and the animal's response.
Dogs & Cats The recommended dose for dogs or cats is 3 mg/lb of body weight administered twice daily by subcutaneous or intramuscular injection.
Cattle and calves Including Non-Ruminating (Veal Calves) From 2mg to 5 mg/lb of body weight once daily by intramuscular injection. Do not treat for more than 7 days. In all species, 3 days treatment is usually adequate, but treatment should be continued for 48 to 72 hours after the animal has become afebrile or asymtomatic.
CONTRAINDICATIONS: A history of allergic reactions to penicillin, cephalosporins or their analogues should be considered a contraindication for the use of this agent.
PRECAUTIONS: Because it is a derivative of 6-aminopenicillanic acid, ampicillin for injectable suspension has the potential for producing allergic reactions. If they should occur, ampicillin for injectable suspension should be disontinued and the subject treated with the usual agents (antihistamines, pressor amines, corticosteroids).
