General Administration Guidelines

• Use a 16-gauge, ½ to ¾ inch sterile needle for cattle; 16- or 18-gauge for swine (18- or 20-gauge for younger pigs).
• Use automatic syringe equipment for 50 mL, 500 mL, or 1000 mL packages.
• Disinfect the injection site and rubber stopper with alcohol before use.
• Do not exceed 10 mL per injection site in cattle. Divide larger doses accordingly.

Recommended Parasite Control Program

Swine: Treat all breeding animals initially. Continue as follows:

• Sows: 7–14 days before farrowing
• Gilts: 7–14 days before breeding and again before farrowing
• Boars: At least twice annually or as needed
• Feeder Pigs: Treat before moving to clean quarters

Important Notes

1. Ivermectin has persistent activity against mites but does not immediately kill eggs. Avoid exposure to uninfested animals or environments for at least one week post-treatment.
2. Louse eggs are unaffected—monitor for reinfestation and retreat if needed.
3. Consult a veterinarian for diagnosis and integrated parasite management.

Minor Species Use

• Reindeer: For warbles (Oedemagena tarandi), inject 200 mcg/kg subcutaneously.
• American Bison: For grubs (Hypoderma bovis), inject 200 mcg/kg subcutaneously.

Residue Warnings

• Cattle: Do not treat within 35 days of slaughter. Not for use in female dairy cattle of breeding age or pre-ruminating calves.
