Can I give my dog Simparica and Interceptor together safely?

It is ok to give trifexis and simparica together (staggered by 2 weeks is great). Both of those medications will protect against fleas so there is some overlap with that. If you want to streamline how many medications you are giving Dakota monthly, Another option would be to use sentinel or interceptor instead of the trifexis and give with that with simparica monthly. These products contain the same heart worm preventative (milbemycin) as trifexis but do not contain any medication to kill adult fleas. (Trifexis contains both the milbemycin for heart worm prevention and Spinosad for fleas). That way you would be giving one medication for heart worm prevention (sentinel or interceptor ) and one for flea and tick prevention (simparica). Another option is to continue trifexis and add in a tick collar (such as the preventic collar or the seresto collar). I know there are so many products and options it is confusing ! Let us know if you have any other questions. And great job with preventative care.

Yes, you can give both products at the same time and Charlie will likely do fine. If you want to be extra cautious, separate them by two days. Neither product had activity against ticks. If ticks are a concern where you live, you can switch the products to something like Simparica for fleas and ticks and the Interceptor for heartworms and intestinal worms. There’s not really a reason to use three different products. I hope this is helpful and please feel free to post any additional questions.

Hi there and thank you for using pet coach! Yes, it is safe to use both products together. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Hi there. While there's technically no reason that these two medications can't be used together, they are both heartworm preventatives - so there's quite a bit over overlap in what they do, and both should not be needed at the same time. If your pup is currently on Interceptor and you want to add a second medication to cover fleas, I would recommend using something like Nexgard or Bravecto - these are flea/tick meds only, so you wouldn't be treating her unnecessarily for heartworms with two different meds.

Hello. This is fine to use. I would not recommend giving both of these on the same day. Give one on the first of the month & the second on the 15th so there are no drug interactions. Thanks for using Petco Pet Education Center, formerly Petcoach.

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 and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. No, your dog should not get sick from these medications combined. While they are not needed together, they do not interact negatively, so Mario should be just fine! I hope this is helpful!
