From what you describe she is experiencing paranoid delusions. Her mental condition can be caused by this drug, but she may have had a psychotic break. If it is the medication, the cessessation of using it will remedy the condition. The psychosis attributed to Accutane is usually hallucinations (seeing things), not delusions (blatanly false beliefs). However whatever the cause, she is serious danger with impaired judgement and a risk to herself and possibly others. I would contact the police and describe her state of having a "mental breakdown. I would contact all the local emergency rooms and and inquire if she was admitted. My heart goes out to you during this especially traumatic time. If she returns home you need to have her hospitalized by calling 911 and having her taken by ambulance to the hospital for evaluation and stabilization. Best wishes and good luck.
