Dosing
& Administration

The low-volume dosage of Macrosyn enables you to use less product per animal compared to most other antimicrobials—that means one bottle goes a long way.

To administer Macrosyn, inject intramuscularly as a single dose in the neck at a dosage of 2.5 mg/kg (0.25 mL/22 lb) BW.  Do not inject more than 2.5 mL per injection site.
