I Manage A Clean And Sober Living House, But We

I manage a clean and sober living house, but we have a resident who is the mother of one of our clients who needed a place to go, so we rent a room to her. She has been violently throwing up for about an hour and she just stated to me that she has been out of her Thyroid medicine for 8 days. I believe it is called Levoxyl? She is 63, slightly overweight and has some mild cognition problems. She seems to be resting right now. Do I need to get her to the hospital right away?
