Hi there! My name is ***** ***** I'm happy to help you with your question today.
So I looked up the MSDS (material safety data sheet) for Hyland's and found that it contains only very, very micrograms of a subset of quinine...not the actual product itself....which is a good thing.
I don't expect there to be any problems here.
You may see her getting some vomiting and/or diarrhea, but generally this resolves on it's own in 24 hours.
That being said...if you notice her being incredibly lethargic, if she becomes anorexic, has blood in vomit or diarrhea, or if she has any problems with coordination then you should have her seen by an emergency vet in your area, but I really don't think it's going to be an issue here.
Even if she's fine until morning, you should still give your regular vet a call in the morning, just to be on the safe side.
