How many minutes ago did she ingest this?
Okay. Give her 1 teaspoon of hydrogen peroxide by mouth and she should vomit in about 15 minutes. Make sure to catch the vomit and identify the tablet in it. I will wait around to make sure she gets the tablet up. You can repeat this once if necessary.
I'm sorry ... I waited the appropriate amount of time doubled for you to get back with me. I would take her to the vet and let them check her liver enzymes. Most likely she will be okay but there is a possibility that it could affect the liver and they can tell from a quick blood test.
