Features and Benefits

Think Gram-positive

  • 95 percent of dry cow mastitis is caused by Gram-positive pathogens2
  • DRY-CLOX provides bactericidal activity against Gram-positive bacteria - Strep agalactiae, penicillin-resistant Staph aureus and non-penicillinase-producing Staph aureus.
  • In a study, 98% of the Staph aureus isolates tested were sensitive to cloxacillin benzathine.3

Proven Efficacy

  • In a head to head trial between DRY-CLOX and ceftiofur hydrochloride, there were no statistical differences between the following parameters2:
    • Infections at calving
    • Risk for cure
    • Risk for new infection
    • Risk for clinical mastitis at 100 days in milk
    • Risk for culling
    • DHIA test performance for milk, percent butterfat, percent protein and SCC up to 100 DIM.

Long Lasting Activity With Zero Milk Withhold*

  • A zero milk withhold from dry pen to bulk tank lets your cows go right back to being profitable members of your herd.
  • DRY-CLOX offers the option of a 30-day dry period.

*Zero milk discard period after calving following a 30-day dry cow period.

Dosage Information

At dry off, at least 30 days prior to calving, infuse a 10 mL syringe (500 mg cloxacillin activity per syringe) once each quarter has been completely milked out.

Safety Information:

For use in dry cows only. Do not use within 30 days of calving. Any animal infused with this product must not be slaughtered for food until 30 days after the latest infusion.

Because it is a derivative of 6-aminopenicillanic acid, DRY-CLOX has the potential for producing allergic reactions. Such reactions are rare; however, should they occur, the subject should be treated with antihistamines or pressor amines, such as epinephrine.

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