Quick Facts Scannable

Used to treat various parasitic infections in dogs.
Works by disrupting the nerve and muscle function of parasites, ultimately leading to their death.
Available in liquid form for ease of administration.
Commonly used for heartworm prevention and treatment of mites, lice, and other parasites.

What It Is and How It Works

Ivermectin is a broad-spectrum antiparasitic agent used to control multiple types of internal and external parasites in dogs. It belongs to the avermectin class of drugs and works by binding to specific ion channels in nerve and muscle cells of parasites. This binding leads to paralysis and death of the parasites by causing an increase in the permeability of cell membranes to chloride ions, leading to an interruption of neural signal transmission.

Indications / Uses

Liquid ivermectin is mainly used in veterinary medicine to treat and prevent a variety of parasitic infections in dogs. These include heartworm disease prevention, treatment of mite infestations like sarcoptic mange, and control of lice. It may also be used to treat certain gastrointestinal worms, though its primary indication remains heartworm prevention. Its use should always be governed by a veterinarian’s prescription and specific guidance.

Dosage Forms and Typical Dosing Considerations

Ivermectin for dogs is available in several forms, with the liquid formulation being favored for its easy administration, especially in small or uncooperative dogs. The dosage of ivermectin can vary significantly based on the intended use, the dog\’s weight, and its overall health. Due to potential toxicity, especially in overdose or in breeds susceptible to drug sensitivity, dosing requires precise calculation by a veterinarian based on the specific needs of the dog.

How to Take It Correctly Step-by-Step

Consult your veterinarian before use to determine the correct dosage and administration method.
Administer the liquid form orally, following the vet\’s orders precisely. Use a syringe for accuracy if necessary.
Ensure your dog has a small meal beforehand to minimize gastrointestinal discomfort.
Give the dose at regular intervals as prescribed, without missing or doubling doses.
Store the medication in a cool, dry place, away from direct sunlight to maintain efficacy.
If a dose is missed, contact your veterinarian for the best course of action rather than guessing or administering extra doses.

Side Effects Common to Serious

Common Side Effects

While generally well-tolerated, ivermectin may cause mild side effects, such as drooling, vomiting, and diarrhea, particularly at the beginning of treatment.

Less Common Side Effects

Occasionally, dogs may experience lethargy or temporary drowsiness. Observing your pet after administration is recommended to ensure they do not exhibit unusual behavior.

Serious or Rare Side Effects

In some cases, especially where toxicity occurs, dogs may exhibit severe signs such as tremors, ataxia, hypersalivation, or seizures. This is more common in breeds with genetic sensitivity to ivermectin. Urgent veterinary care is essential if any of these symptoms are observed.

Contraindications & Precautions

Ivermectin should be used cautiously in dogs known to possess the MDR1 gene mutation, affecting some herding breeds, which may cause increased drug sensitivity leading to toxicity. Pregnant and lactating dogs or those with preexisting liver conditions may also require special dosing adjustments or alternative treatments.

Drug, Food, and Supplement Interactions

The potential for interaction requires careful handling of ivermectin when given with other medications such as spinosad, which can enhance toxicity. Dogs should not receive ivermectin concurrently with certain oral parasite preventatives without veterinary approval. Always disclose all medications, supplements, or herbal products your pet is receiving to the veterinarian to avoid adverse interactions.
