Accidentally gave my dog a second dose of heartworm meds—should I call the vet or wait it out?

I accidentally gave my dog a second dose of her heartworm medication this morning because I forgot I had already given it to her earlier in the week. I'm worried about how this might affect her. Should I be calling you right away, or is it something that might just work itself out without causing harm?

Answer

Accidentally giving your dog a double dose of heartworm medication can be concerning, but in most cases, it is not immediately dangerous. Monitor your pet for any adverse reactions.

  • Monitor your dog for any unusual symptoms.
  • Potential mild side effects like vomiting or diarrhea can occur.
  • Contact a vet if you're worried or notice any concerning symptoms.

Heartworm medications have a wide margin of safety, which means most dogs tolerate an extra dose without severe problems. However, you should observe your dog over the next 24-48 hours for signs like vomiting, diarrhea, lethargy, or drooling. These symptoms are generally mild and short-lived, but if they persist, consulting a vet is advisable to ensure your dog's safety and well-being.
