HELP, dog ate Prevacid

[noirsphynx]

I just discovered while I was out that my 60lb dog ate approximately 15-20 30mg prevacid pills(lansoprazole) does anyone happen to know how worried I should be? It's probably been a few hours since it happened but he seems fine. I called my vet but they weren't much help other than giving me the animal poison control # which charges $ just to give me an answer.
