My mom 53 yrs old, inhaled some "all out" mosquito repellent last night in the process of sis spraying it upon a spider. Today early morning, around 4am she vomitted, and feeling tired throughout the day. She says it's just small amount and that she is fine. How serious might that be? She says we should wait till tomorrow to see the doctor.
