My puppy got adult Simparica Trio, adult dog got puppy dose. Help!

Hello, thank you for using PetCoach. Please understand that we are not an emergency service. If you are worried your pet have ingested something toxic you need to call your local veterinary emergency clinic or ASPCA Animal Poison Control as we cannot guarantee a prompt response. Some toxicities are true emergencies and can be fatal. ( https://www.aspca.org/pet-care/animal-poison-control ) Typically speaking most (not all) animals that ingest a double dose of a preventive medication are safe however, not all animals react to medications the same way. The best you can do if it has been more than an hour since he ingested it is to watch for symptoms of toxicity like: tremors, seizures, ataxia (walking drunk/unsteady), extreme lethargy, vomiting, etc. If you notice any symptoms get him to an emergency clinic ASAP. As an aside, according to studies done by Zoetis who make Simparica, "In the overdose groups, transient and self-limiting neurological signs were observed in some animals: mild tremors at 3 times the maximum exposure dose and convulsions at 5 times the maximum exposure dose. All dogs recovered without treatment." Again, this won't hold true for every individual. Hope this helps. Best wishes.

Simparica has a wide margin of safety, but Abby ingested 4 times her normal dose. You may see tremors or convulsions within the next 24 hours. These symptoms are typically self limiting and, in safety studies, resolved without treatment. Ideally, she should be examined at the nearest veterinary ER. Vomiting can be induced via injection followed by administration of activated charcoal to further reduce absorption. This is most effective when done within an hour or two of ingestion. There is no antidote for sarolaner (the active ingredient in Simparica) overdose, so treatment is largely supportive and symptomatic until recovery is complete. This may include IV fluids and medications to control tremors or convulsions if they develop.

Thank you for contacting Petco Pet Education Center with your question about Rockelle. She should be ok. According to studies done by Zoetis who make Simparica, "In the overdose groups, transient and self-limiting neurological signs were observed in some animals: mild tremors at 3 times the maximum exposure dose and convulsions at 5 times the maximum exposure dose. All dogs recovered without treatment." You don't need to do anything. I hope this helps!

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. If Henk ingested the tablets in the last 1-2hrs, you should take him to your local vets right away to induce vomiting. If it was longer than 2hrs, making him vomit would not be recommended. If that is the case, you should monitor Henk at home for symptoms of vomiting, diarrhea, lack of appetite, tremors, problems with balance. If you notice any of these symptoms, you will have to get him to your local vets as soon as possible.

No, it's not safe to give half a dose. You can't be sure you are giving Sahara exactly half of the medication, and you could accidentally overdose her. I would return the Simparica, and get the correct dosage for her weight.

As long as Jasper is older than 6 months of age and weight more than 2.8lbs, it should be safe. By your information, that appears to be the case. Lethargy and gastrointestinal upset (vomiting or diarrhea) are the most commonly reported side effects.

So this medication contains a combination of Spinosad and Milbemycin. Milbemycin is used in dogs as a heartworm prevention, and can safely be given at two to four times the normal dose used for heartworm prevention. Spinosad is used for flea prevention, and it is a relatively safe drug. The most common side effects seen with its use include a decreased appetite, diarrhea, vomiting, and lethargy. Studies on research dogs showed no long term effects on dogs that were given ten times the recommended dose. More than likely, Molly will be just fine, but if you see any of the side effects that I mentioned above, have her seen by a vet just to be safe. Best of luck, I hope this helps!
