The hydroxyzine is an approved medication in dogs and his normal dose would be 50 mg twice a day. You are unlikely to notice any side effects from that tablet. However cymbalta is not used in dogs but his toxic dose for his weight is around 300-400 mg. The side effects of that medication include vomiting, disorientation, lethargy and tremors. If it has been under an hour you can induce vomiting and see if he throws anything up so it won't be absorbed. If it is longer than hour you can watch for those symptoms.
