My dog got Interceptor Plus after a Proheart shot. Is she okay?

Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear Pepper had a mixup with her medications. Fortunately, those drugs do not typically interact negatively with each other and theoretically should not cause any issue. I would monitor for any vomiting, inappetence, excessive sedation, incoordination, etc. for 24 hours but wouldn't anticipate that you would see any signs. If you are concerned or she begins acting abnormally, I would recommend reaching out to your regular veterinarian or ASPCA poison control for further advice.

Hello and thanks you for your post on Petco Pet Education Center, formerly Petcoach this afternoon! Yes, this should be okay. Although both are oral heart worm and intestinal parasite preventatives and typically speaking, giving two heart worm preventatives together or within a short amount of time is not recommended, combining these two preventatives together accidentally one week apart should not result in a negative reaction. Sam may have some transient diarrhea or vomiting, however. I hope this helps put your mind at ease and best wishes to you and Sam!

Hello. There should be no problems giving the Pro Heart on top of the Trifexis. Just monitor for any indications of Loki not feeling well, vomiting, diarrhea or loss of appetite for the next couple of days, but there should be no long term issues with this.

If Grace has been entirely normal since the episode of vomiting I don't think you have anything to worry about. Of course, continue to monitor for any signs of ill health like vomiting, diarrhea, lethargy, or inappetance. Thanks for using Petco Pet Education Center, formerly Petcoach and best wishes to you and Grace!

You did exactly the right thing by calling around to vets to ask for help right away. It's always best to check when you aren't sure, and are worried about your pet. The Triheart dose that we give dogs for heart worms has very small doses of the two medications that are in it. Ivermectin is one of the medications that is in the Tri heart. The dose is 68 micrograms. Veterinarians use this medication also to treat dogs with skin mites and use a dose over 100 times the dose in one heart worm preventive tablet. Therefore, even if she would have eaten two or three boxes of the Triheart she should be very safe and there is not any risk of an overdose of the ivermectin. The other medication is called pyrantel pamoate which is used for deworming of intestinal parasites. This medication has a very large safety margin also, and can be given at 10-20 times the normal dose without any risks of toxicity. Therefore, just like with the ivermectin in the Triheart Plus, I would not expect any potential side effects either. These potential side effects could include an upset stomach, mild diarrhea, and/or vomiting. Monitor her for those side effects, and bring her into your vet in the morning if you are still concerned.

One of the active drug ingredient in both meds is milbemycin, so if the allergy or reaction to was that specific drug, it would be better to avoid it. Of course we can't know that for sure. It may be that Rexy is allergic to one of the other active ingredients in trifexis, or to one of the inert ingredients. However, I think the best recommendation would be to use a prevention that does NOT contain milbemycin or praziquantel (the ingredients in Trifexis). Heartgard is a good alternative. Make sure that he is up to date on his heart worm test first. I think its fine to go ahead and get him started on a different heart worm prevention ASAP, even though he just had surgery. I hope that helps you ! Thanks for asking Petco Pet Education Center, formerly Petcoach!

Intestinal parasites are spread in the feces of infected animals so as long as you sister is picking up after her dogs your dogs should be fine. Also, since your dogs are receiving a monthly heartworm preventative they will be protected from any infestation. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach.
