Accidentally gave my hamster 0.5ml metacam- will he be okay?

I went to the vet and they prescribed this medication for him. I have been giving him 0.5ml instead of 0.05ml. This is because when the vet showed me how much to give him on the syringe type of thing he showed it up to the 0.5ml by accident I’m guessing. But now I have given him this dose for 3 days straight. Will he be ok? I just gave him another dose now and I also realised right now.
