How Does Ivermectin Work?

Ivermectin belongs to a class of drugs called macrocyclic lactones. It works by paralyzing and killing parasites that have nerve systems. The drug targets glutamate-gated chloride channels, which are present in the nervous system of invertebrates but absent in mammals. This selective action allows ivermectin to effectively eliminate parasites without harming the dog.

When administered, ivermectin is absorbed into the bloodstream and distributed throughout the body. It remains active for an extended period, providing long-lasting protection against parasites. The drug's persistence in the body contributes to its effectiveness, but it also necessitates careful consideration of dosage and potential side effects.

Ivermectin vs. Other Antiparasitic Drugs

Compared to other antiparasitic drugs, ivermectin offers a broad spectrum of activity. It's effective against parasites that are resistant to other treatments, making it a valuable option in certain cases. However, some newer drugs may have fewer side effects or be more convenient to administer.

While ivermectin is a cost-effective choice, other options like fenbendazole and pyrantel pamoate may be preferred for routine deworming. The choice of antiparasitic drug depends on the specific parasite, the dog's health status, and the owner's preferences. Always discuss treatment options with your veterinarian.

When to Use Ivermectin?

Ivermectin is commonly used to treat and prevent heartworm disease in dogs. It's also effective against intestinal parasites like roundworms, hookworms, and whipworms. Furthermore, it can be used to treat skin infestations caused by mites, such as sarcoptic mange and demodectic mange.

Veterinarians often prescribe ivermectin for dogs diagnosed with heartworm disease. It's administered in a specific dosage and schedule to eliminate adult heartworms and prevent the development of new infections. Regular preventative measures, including monthly ivermectin administration, are crucial for maintaining heartworm-free status.

Available Forms and Composition

Ivermectin is available in various forms, including oral tablets, topical solutions, and injectable formulations. The most common form for dogs is an oral tablet, often found in over-the-counter products. The active ingredient is always ivermectin, and the dosage varies depending on the dog's weight.

Topical ivermectin solutions are applied directly to the dog's skin and absorbed through the bloodstream. These formulations are often used for treating skin infestations like mange. It's important to follow the manufacturer’s instructions carefully when using any ivermectin product.

How to Administer Ivermectin?

The correct dosage of ivermectin is crucial for its effectiveness and safety. It's typically calculated based on the dog’s weight, with a standard dose ranging from 6 to 12 mcg per kilogram of body weight. Always consult with a veterinarian or follow the instructions on the product label carefully.

When administering oral ivermectin, ensure the dog swallows the tablet completely. Topical formulations should be applied evenly over the affected areas of skin, avoiding contact with eyes and mucous membranes. Regular monitoring for any adverse reactions is essential after administering ivermectin.

When Should You Avoid Ivermectin?

Certain breeds of dogs, such as Collies, Australian Shepherds, and related herding breeds, are highly sensitive to ivermectin due to a genetic mutation affecting their ability to metabolize the drug. Administering ivermectin to these breeds can lead to severe neurological toxicity.

Pregnant or nursing dogs should not be given ivermectin unless specifically directed by a veterinarian. Dogs with known allergies to ivermectin or other macrocyclic lactones should also avoid this medication. Always inform your veterinarian about any pre-existing conditions or sensitivities before using ivermectin.

Potential Side Effects of Ivermectin

Common side effects of ivermectin are usually mild and transient. These may include vomiting, diarrhea, lethargy, or itching. These symptoms typically resolve within a few hours or days without intervention.

Rare but serious side effects include neurological signs such as tremors, seizures, ataxia (loss of coordination), and coma. These reactions are more likely to occur in sensitive breeds or with overdose. Seek immediate veterinary attention if you notice any concerning neurological signs.

What to Do in Case of Overdose?

Signs of ivermectin overdose can include dilated pupils, drooling, tremors, incoordination, and seizures. If you suspect your dog has ingested too much ivermectin, contact your veterinarian or an emergency animal hospital immediately.

Treatment for ivermectin overdose typically involves supportive care, such as intravenous fluids to maintain hydration and anticonvulsants to control seizures. Activated charcoal may be administered to prevent further absorption of the drug from the gastrointestinal tract.

Alternatives to Ivermectin

Several other antiparasitic drugs can be used as alternatives to ivermectin. Fenbendazole and pyrantel pamoate are commonly prescribed for routine deworming, while selamectin and fipronil are effective against fleas and ticks.

For dogs with heartworm disease, milbemycin oxime and moxidectin are alternative macrocyclic lactones that can be used under veterinary supervision. The choice of antiparasitic drug depends on the specific parasite, the dog's health status, and the owner’s preferences.
