My dog has diarrhea after taking Trifexis. What should I do now?

Bravecto may cause diarrhea in some dogs. If Gunner is behaving normally otherwise, withhold food for 24 hours. Allow small amounts of water or unflavored PediaLyte as log as he is not vomiting. Resume feeding a bland diet in small, frequent amounts. Feed this way until the stool is normal before transitioning solely to the regular diet. A bland diet is plain white rice mixed with one of the following: cottage cheese, ground turkey, ground beef (cooked/drained) or boiled boneless/skinless chicken breast. If the diarrhea does not stop or if Gunner develops other symptoms (lethargy, loss of appetite, vomiting, etc.), then have him seen by your veterinarian.

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.

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.

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.

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!

The age and pound limit for puppies is 8 weeks and 5 lbs. It would appear that Luna is within this range. The most common listed side effects for Trifexis include itchiness, anorexia, lethargy, redness and diarrhea. Often drugs may have other side effects that are considered uncommon and/or rare. There is also the possibility of allergic reactions to medications. If Luna appears to be in true distress to you, I would recommend getting her into a vet particularly if these side effects happened immediately after using the drug. Intervention may be required, and time is of the essence in smaller, younger patients. Hope this helps.

No, this isn't typical. Keep a close eye on her, and take her back into the vet in the morning if the symptoms persist. If she starts vomiting, has diarrhea, starts having trouble breathing, gets a rash or hives, or her face starts swelling, bring her into an ER vet immediately. Best of luck.
