Quick Facts
- Used primarily for controlling parasitic infections in cattle.
- Works by paralyzing and killing parasitic worms and mites.
- Commonly administered as a subcutaneous injection.
- Effective against a range of internal and external parasites.
- Dosage must be calculated accurately based on cattle weight.
- Potential for adverse effects if overdosed.

What It Is and How It Works
Ivermectin is an antiparasitic agent that belongs to the avermectins class. It disrupts parasite nerve signals by enhancing the release of gamma-aminobutyric acid (GABA). This action paralyzes and potentially kills the parasites, thereby eliminating them from the host animal.
For cattle, ivermectin injectable is used against various nematodes, lungworms, cattle grubs, mites, and lice, providing a broad spectrum of activity against internal and external parasites.
Indications / Uses
Ivermectin injectable is approved for use in cattle to treat and control:
- Gastrointestinal roundworms
- Lungworms
- Grubs
- Sucking lice
- Mange mites
Ivermectin is especially beneficial in regions where these parasitic conditions are prevalent among cattle.
Dosage Forms and Typical Dosing Considerations
The injectable form of ivermectin for cattle is commonly available at a concentration of 1% solution. The dosage is typically administered as a single subcutaneous injection at a dose recommended by a veterinarian based on the animal\’s weight.
Factors influencing dosing include the size and condition of the cattle, the type and severity of the parasitic infection, and special considerations like pregnancy or concurrent illnesses.
Always follow professional guidance and prescription labels accurately to prevent under- or overdosing.
How to Take It Correctly Step-by-Step
- Verify cattle weight to determine the correct dose.
- Ensure the formulation is the appropriate one for cattle.
- Administer subcutaneously as per veterinarian instructions.
- Avoid dosing in animals under stress or with compromised health.
- Follow safety protocols to avoid self-injection.
- Do not exceed recommended dosage or frequency.
Incorrect dosage or administration can lead to ineffective treatment or adverse reactions.
Side Effects Common to Serious

Contraindications & Precautions
Cattle should not be treated with ivermectin if they have known hypersensitivity to ivermectin or any of its components. Use caution in young calves or those with underlying health conditions.
Pregnant cattle should be treated only under professional supervision, ensuring safety for both the dam and fetus.
Drug, Food, and Supplement Interactions
Interaction with other antiparasitic drugs can enhance or reduce effectiveness and safety. Ivermectin should not be combined with drugs that could potentially enhance its neurological effects unless overseen by a veterinarian.
Ensure a full list of current medications and supplements are communicated to the veterinarian before administrating ivermectin.
