Is 227mg of ivermectin too much for my dog to prevent heartworms? I'm really worried I messed up.

I just gave my dog a dose of ivermectin, and I'm really worried I might have given too much. The package says it’s 227mg, and now I’m second-guessing if that’s the right amount. Could you please tell me if 227mg is a safe dosage for preventing heartworms, or if I should be concerned about any potential side effects?

Answer

You're worried about giving your dog an incorrect dose of ivermectin, and you want to ensure that 227mg is safe for heartworm prevention. It's important to double-check dosages based on your dog's size and specific needs.

  • 227mg may be a high dose depending on your dog's size.
  • Signs of ivermectin toxicity include drooling, lethargy, vomiting, and seizures.
  • It's crucial to follow veterinary guidance for medication dosages.

Ivermectin is commonly used in low doses for heartworm prevention. The typical dose is micrograms per kilogram of body weight, not milligrams. A dose of 227mg could be significantly more than recommended, which can cause toxicity, especially in certain breeds. If you're concerned about any symptoms your dog may have, it's best to consult with a vet immediately.

If this is an emergency, please seek immediate veterinary care.
