My dog missed Simparica. Can I double up or give the next dose?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Yes, Simparica and Interceptor can be given together at the same time. BUT if this is the first time giving one or both of the drugs then I would give one at a time 2 days apart in case one causes a problem. Then if there are no issues give them together next month. Have a great day!

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!

Simparica is a once a month flea and tick preventive medication and giving it daily will soon overdose your dog and possibly cause severe health problems and death. So please, give Simparica only as instructed on the label. A one time application will likely be enough to kill the mange. If not, ask your vet to prescribe Bravecto (one-time application) for your dog. You can give Omega 3 fatty acids daily.

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.

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.

No worries. The one on the left (Simparica) should be given every 30 days and the one on the left (Milbemax) should only be given once initially and then again in 2 weeks for the treatment of roundworms and hookworms. Although if Jake only had tapeworms it only requires one treatment of the Milbemax. Tapeworms, if found in your pets stool, are caused by ingesting a flea, so reinfection is possible if you don’t keep up with giving the Simparica on time every month. I hope this helps. Best wishes and take care!

You can safely use one after the other if you wait at least 2 weeks in between applications. So since it has been 3 weeks, then you are ok to switch to Simparica now. I would also recommend treating the condo with a flea fogger purchased from your local Home Depot or Lowe's. Thanks for visiting Petco Pet Education Center, formerly Petcoach and I hope that you get rid of your flea problem soon! Take care.
