My dog throws up NexGard with food. What can stop the nausea?

That could happen after administration of Nexgard, even though is quite unusual and it is more likely to be dietary related. I would suggest to withhold food for the next 4 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhea, vomiting, lethargy or inappetence.

IF they vomited within an hour of the medication, then the medicine did not digest to work for them. This is the most common side effect of Comfortis and seems to be so often, I have quit recommending it. I have had great success with flea control and no vomiting side effects by using Nexgard for monthly or Bravecto given every 3 months. I would recommend changing products and if redosing them immediately if they vomited under an hour of getting the Comfortis.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If Chockey vomited 2-3 hours after you gave the Nexgard, it is likely that the tablet was digested and that he has the preventative in his system. If he vomited shortly after you gave the tablet, it is possible that he vomited up the nexgard. If you want to use a collar this should be absolutely fine as it is more of a topical preventative and not a systemic. Please let me know if you have any other questions or concerns and I would be more than happy to help you further!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Blitz! It is possible that it is from the Nexgard. There isn’t a specific medication to counteract the effects, just supportive care. I would contact your vet so they can report the reaction to the company. Sadly, as with any medication, there is potential for negative side effects with Bexgard. It is generally very well tolerated and it is very effective. Vomiting and diarrhea are reported side effects in the drug insert provided by the company. I have never heard of frequent ruination. It sounds like Blitz should have a recheck to make sure he is stable and to provide supportive medications for his symptoms. I wish you both the best!

Yes. Like all medications, there can be side effects, including vomiting and diarrhea. Here is the product insert that discusses everything about the medication. Look at the section called "Adverse Effects": https://nexgardfordogs.com/assets/NexGard_PI.pdf

I'm sorry to hear that Boo hasn't been feeling well! It is possible that the permethrin spray or collars may be related to his vomiting, but other possible causes include a foreign body intestinal obstruction, virus, parasites (particularly tapeworms since they can be transmitted by ingesting infected fleas), among others. At this point, I recommend leaving his flea collar off and bathing Boo in original blue Dawn dish soap to remove any residue remaining from the permethrin sponge bath. Withhold food for the next 12 hours, then gradually offer very small frequent meals of a bland diet of boiled white meat chicken and white rice for a few days. After a few days, gradually mix the bland diet with his normal food over another 5-7 days. If Boo continues to vomit, develops diarrhea, becomes lethargic or stops eating, he will need to go to his vet for further evaluation. Once he vomiting resolves, be sure that Boo is regularly receiving a high quality flea preventative, such as Nexgard, Bravecto, or K9 Advantix II. I hope that he feels better soon!

No worries. You can safely switch up flea medication every 2-4 weeks no problem. All flea prevention is labeled as safe for dogs but pets can have adverse reactions to just about any medication unfortunately. But these are not expected to happen. I have seen fewer reactions with Nexgard if that is any consolation. : ) Best wishes with your pet Jack moving forward and I hope that he tolerates Nexgard well! Take care.
