What It Is and How It Works
Durvet Ivermectin Pour-On is a topical solution specifically formulated for cattle to manage parasitic infections. Ivermectin, the active ingredient, is a broad-spectrum anti-parasitic agent that works by binding to specific sites in the parasites\’ nervous system, causing paralysis and death of the parasite. This mechanism effectively eliminates a wide range of parasites, including gastrointestinal roundworms, lungworms, and certain external parasites such as lice.
Indications / Uses
Durvet Ivermectin Pour-On is primarily indicated for treating and controlling various internal and external parasites in cattle. It is effective against gastrointestinal roundworms, lungworms, cattle grubs, sucking lice, and biting lice. Its use ensures better health and increased productivity in the herd by minimizing parasitic burdens.
Dosage Forms and Typical Dosing Considerations
The pour-on formulation of ivermectin is designed for easy application along the backbone of cattle. The dosing is generally based on the weight of the animal, and it is crucial to follow the specific dosage recommened by a veterinarian or the instructions on the product label. Overdosing and underdosing can both lead to ineffective treatment or adverse effects.
Factors such as age, breed, health status, and parasite burden may influence the dosing decisions. Special considerations are necessary when using it on lactating cows, as the milk withdrawal period must be strictly adhered to.
How to Take It Correctly Step-by-Step
- Determine the weight of the cattle to calculate the appropriate dose.
- Ensure the animal is restrained and calm to prevent injury during application.
- Pour the correct amount of ivermectin solution along the topline of the animal from the withers to the tail base.
- Avoid applying to wet or dirty skin to ensure proper absorption.
- Do not wash or expose the animal to the rain immediately after application, as this may reduce effectiveness.
- Store the product in a cool and dry place, away from sunlight and out of reach of children.
Side Effects Common to Serious
Common Side Effects
Most cattle tolerate the pour-on ivermectin well, but some common side effects could include:
- Minor skin irritation or itching at the site of application.

Serious or Rare Side Effects
- If systemic reactions occur such as neurologic symptoms or severe skin reactions, contact a veterinarian immediately.

- Use caution in cattle intended for human consumption and comply with withdrawal periods.
- Avoid use on lactating dairy cows intended for human milk consumption unless label directions indicate safety.
- Special considerations should be given to pregnant or debilitated animals.
Drug, Food, and Supplement Interactions
While ivermectin has minimal known significant drug interactions in cattle, it is important to inform a veterinarian of all medications and supplements the animals are receiving. This includes other parasiticides, nutritional supplements, or any newly introduced medications that might interfere with its effectiveness or safety.
