How can you help someone who took 15 advil (ibuprofen) pm. to kill themselves?

Call 911: They need emergency help right now. The problem goes beyond just what they took. The mere fact that they tried to kill themselves is an emergency itself.

That person needs to: be evaluated in an emergency room for both suicidality and for medical effects of drug overdose. May need to call 911 for assistance with emergency transport.
