My puppy vomited and is lethargic after Trifexis. What should I do?

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.

If there are no other symptoms and she is still eating and drinking normally you can probably wait until Monday to have her examined. I doubt the recent vaccines and Trifexis are related. If she vomits or has diarrhea, if she isn’t eating or if she is so lethargic you can’t rouse her you should see an emergency vet.

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.

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.

Thank you for submitting your question regarding Junior. It is unlikely that he is experiencing a reaction from the vaccinations or the Trifexis given the amount of time in between. Reactions to both are possible, but in my experience will happen the same day. If his symptoms recur, I would recommend that he sees his veterinarian, but I am happy that he is feeling better 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!

Diarrhea can be a side effect of any antiparasitic medication. As long as Butter is behaving normally otherwise, you can manage it at home. Withhold food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet in small, frequent amount until symptoms resolve. Begin with 1 tablespoon of food every hour and gradually increase the amount. Feed bland until the stool is normal then transition slowly to the regular diet. Symptoms to monitor for and that should be addressed by your veterinarian include lethargy, vomiting, persistent diarrhea, loss of appetite or abdominal pain.
