My dog vomited after Trifexis heartworm medicine. Is she safe now?

Thank you for submitting your question regarding Fiona. She is unlikely vomiting from the Trifexis if she hasn't in the past. That is a small dose change for her. There are numerous causes of vomiting such as dietary indiscretion, an infection, stress or something more serious such as eating a foreign object. If she still refuses to eat or cannot keep food or water down, then she will need to see a veterinarian today. Being such a small breed dog, it is easy for her to become dehydrated. If she seems to be feeling better, give her small frequent amounts of water and food throughout the day today. I hope this information helps!

Hi there. Trifexis has a very wide margin of safety (a dog could eat an entire box and not have any serious issues, in most cases), so it's unlikely that this will cause any problems. The most likely side effect would be vomiting or GI upset, in the first day or two after taking the meds. If she's acting normal so far, you probably won't see any issues at all. It's fine for her to continue with her normal daily routine as far as eating, exercising, etc.

Toxic reactions of the main ingredient in Trifexis in dogs starts at 400mg/kg. Assuming duke had 6 tablets of 60-120lbs he had a little under 10,000 mg, for his weight toxic dose starts at 12,000 mg, so he should be safe, but if you start seeing worse symptoms or if he isn't better by tomorrow morning- take him to the vet in order to get it checked.

Poor Ember! Vomiting and lethargy are both common side effects of Trifexis, and do not usually indicate any kind of serious problem. But, you could certainly opt to use a different flea and heartworm medication for her in the future to avoid this issue. For tonight, I would withhold food and leave her alone to rest since she doesn't feel well. If she's still acting noticeably lethargic tomorrow, or if she develops any other symptoms, then I would call your veterinarian or take her in for a check-up to make sure nothing else is wrong.

Six hours is sufficient time for Stella to digest the Trifexis. If you didn't see the pill in the vomitus, then she digested it. Typically, another dose is recommended only if vomiting occurs within 1 hour of administration.

This is a very common side effect of Trifexis, if you know for sure that he didn't throw up for the first 2 hours after you gave it to him, then you do not have to treat again. the side effect will last up to 24 hours. next time try to give it a quarter tablet at a time every 15 minutes with food, this can prevent this side effect. alternatively you can switch to a different product.

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.
