What It Is and How It Works
Ivermectin is an antiparasitic medication belonging to the avermectin class. It works by binding to specific ion channels in nerve and muscle cells of parasites, leading to paralysis and death of the parasites. In dogs, it is most commonly used to treat heartworm disease and various external mites.
Indications / Uses
Ivermectin is primarily used in veterinary medicine to prevent heartworm disease and treat other parasitic infections in dogs, such as mites responsible for mange. Importantly, its use should be under veterinary supervision to avoid avoidable risks, specifically in breeds sensitive to the medication.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various formulations suitable for dogs, including oral tablets, chewables, and topical solutions. Dosing typically depends on the dog\’s weight and specific condition. Crucially, a veterinarian\’s guidance is necessary to determine the appropriate dose and to avoid toxicity, notably in Collies and similar breeds that are more susceptible to side effects.
How to Take It Correctly Step-by-Step
When giving ivermectin to dogs:
- Administer as directed by the veterinarian.
- Follow the specified timing and dosage; do not double doses to make up for missed ones.
- Store in a cool, dry place out of reach of children and pets.
- Avoid mixing with alcohol or other medications unless approved by a veterinarian.

Contraindications & Precautions
Ivermectin should not be used in dogs with known hypersensitivity to the drug. Caution is advised for pregnant or nursing dogs and those with existing neurological disorders. Furthermore, some breeds like Collies may require specific dosing adjustments due to their genetic predisposition to ivermectin sensitivity.
