My Daughter Has Been On Aropax For About 3 Months

My daughter has been on aropax for about 3 months and we are very concerned with the affect its had on her.
uncontrolled spending, loss of ability to decide right from wrong, unreasonable behaviour. she has reduced amount in the past week but still is very oblivious to how she is acting, eg running out of petrol regularly, not paying bills...etc all her friends are very worried about her, but the problem is she is 19 and doesn't see a problem...do you have any suggestions.
