My 16 Yr Old Daughter Used Too Much Clorox Bathroom

My 16 yr old daughter used too much Clorox bathroom cleaner and the the bathroom with Windows and door closed. She is now experiencing pain when she breathes. I let her sit outside in cool air to ventilate. She says she feels a little better, but she says it feels like someone is sitting on her chest. Is it okay for her to drink water? At what point, should I consider her being seen by doctor?
