My cat took Onsior 12 hours early. Is he okay? What to watch for?

Pet's info: Cat | Domestic Shorthair | Male | neutered | 1 year old | 11 lbs

My cat was prescribed onsior. I realized that I gave him his medicine this morning with his other 12 hour instead of waiting till tonight. Will he be okay. Do I need to be looking for anything since I have given him the medication 12 hours early

Fortunately Onsior is one of the safest pain killers on the market and a one time double dosage is not likely to affect him. i would still monitor him for vomiting, lack of appetite and bloody stools, i would also recommend skipping the next dose.
