Product Description

POLYFLEX Injectable Suspension is an antibiotic that provides protection against gram-positive and gram-negative bacteria, including bacterial pneumonia.

  • Treats bacterial pneumonia (shipping fever, calf pneumonia and bovine pneumonia)
  • Approved for use in cattle (including lactating dairy cows) and calves (including non-ruminating veal calves)

Features & Benefits

  • POLYFLEX provides bactericidal activity against gram-positive and gram-negative bacteria
  • It is labeled for 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 ampicillin trihydrate.
  • POLYFLEX is approved for use in beef and dairy cattle and calves

Dosage Information

  • Approved for use in cattle (including lactating dairy cows) and calves (including non-ruminating veal calves)
  • Cattle and Calves: 2 to 5 mg/lb of body weight once daily by intramuscular (IM) injection. Do not treat for more than seven days.
  • Three days treatment is usually adequate, but treatment should be continued for 48 to 72 hours after the animal has become afebrile or asymptomatic.

 

Safety Information:

Do not treat cattle for more than 7 days. Milk from treated cows must not be used for food during treatment, and for 48 hours (4 milkings) after the last treatment. Cattle must not be slaughtered for food during treatment, and for 144 hours (6 days) after the last treatment.

POLYFLEX has the potential for producing allergic reactions because it is a derivative of 6-aminopenicillanic acid. If a reaction should occur, discontinue use of POLYFLEX and treat the subject with the usual agents (antihistamines, pressor amines, corticosteroids).

CAUTION: Federal law restricts this drug to use by or on the order of a licensed veterinarian. 

Use POLYFLEX with total confidence.

POLYFLEX (ampicillin) goes beyond conventional penicillin therapy. It offers broad-spectrum activity and reliable meat-withdrawal and milk-withholding times.

Reap the benefits of short withdrawal times.

With POLYFLEX, there is a 48-hour milk and six-day slaughter withdrawal, unlike the variable withdrawal periods associated with the extra label use of penicillin.

Dosage is flexible.

Get low-volume dosage that’s still effective at labeled dose (0.5–1.25 mL/cwt.1 equivalent to 2 mg – 5 mg/lb.).

POLYFLEX is a fast-acting treatment against respiratory tract infections.

It is labeled for 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 ampicillin trihydrate.

POLYFLEX offers a more economic alternative to third-generation cephalosporin drugs.
