This is a rather big overdose, but this drug is relatively safe to overdose. Signs of an overdose can be vomiting and muscle tremors. If you don't see any of these after eight hours, then she will be fine. If you do see vomiting and tremors, then it's best to take her to the vet for treatment and monitoring. It's most likely that she will be OK. Just check on her every so often and make sure she has plenty of water available. I hope that helps and Abby gets better soon.
