Dry-Clox is indicated for the treatment of mastitis in dairy cows during the dry period. Dry-Clox has been shown by extensive clinical studies to be efficacious in the treatment of mastitis in dry cows, when caused by Streptococcus agalactiae and Staphylococcus aureus including penicillin-resistant strains. Treatment of the dry cow with Dry-Clox is indicated in any cow known to harbor any of these organisms in the udder at drying off, or which has had repeated attacks of mastitis during the previous lactation, or is affected with mastitis at drying off, if caused by susceptible organisms.
