My 1 1/2 Year Old Swallowed A Regular Advil Pill.

My 1 1/2 year old swallowed a regular advil pill. Just one he found it at the bottom of my old purse. He isn't acting any different. He did puke after swallowing it I think it was kinda stuck in his throat. I googled but I didn't get any answers. Could you help me. Will he be okay after swallowing 1 advil regular pill.???? It was a 200 mg tablet he just took 1 will he be okay???
