We Are At My Mother In Laws House Who's Getting

We are at my mother in laws house who's getting old and left her xanax out! My 19 month old may have got a hold of some. She doesn't remember how many she had left. They are .5mlg. I can't be positive if he got any. I would assume he would chew it up if he did eat one and spit it out or came to me. But in case he did what should I do?!
