Hi there! Since Primo is 84 pounds (about 38 kilograms), 150 mg of Deramaxx would be a dose of about 4 mg/kg. This is within the approved label dosing range for this medication for short-term use, so it's unlikely that you will see any serious side effects related to this - especially since you were able to make him vomit within about an hour, so he probably vomited up at least part of the medication before it was fully absorbed.

With any higher-than-normal dose of Deramaxx, it's always possible to see GI issues such as stomach upset or even gastric ulcers - so I would recommend monitoring Primo closely for the next few days to make sure that he's acting normal. If he has repeated episodes of vomiting (more than once or twice), doesn't want to eat, or begins acting lethargic, then I would recommend taking him to the vet right away to be checked out.

If he normally takes Deramaxx daily, I would also recommend calling your regular vet in the morning to let them know that this happened - they may recommend skipping his normal dose for the next day or two to help minimize the risk of any problems.
