What It Is and How It Works
Ivermectin pour-on is a topical solution for cattle, designed to treat and control a variety of parasites such as gastrointestinal worms, lice, and mites. It works by binding to specific areas in parasite nerve cells, increasing cell-permeability to chloride ions. This results in the paralysis and eventual death of the parasites, providing extended protection against re-infestation.
Indications / Uses
Ivermectin pour-on is primarily used in cattle to combat internal and external parasites. Approved indications include treatment and control of gastrointestinal roundworms (e.g., Ostertagia ostertagi), lungworms, cattle grubs, lice, and mites. While primarily intended for these conditions, any off-label use should be prescribed by a licensed veterinarian.
Dosage Forms and Typical Dosing Considerations
The pour-on formulation makes application straightforward; however, proper dosage based on weight is crucial for effectiveness and safety. Typical dosing considerations consider the weight of the cattle, any underlying health conditions, and the presence of other medications or treatments. Dosages should be strictly administered as per the product\’s label or veterinary instructions.

Applying ivermectin pour-on involves the following steps:
- Ensure cattle are dry and clean before application.
- Weigh cattle to determine the correct dose.
- Apply the product along the backline of the animal using the dispenser provided.
- Avoid overdosing by double-checking weight and measurements.
- Store the product per the label\’s recommendations to maintain efficacy.
