Welcome to our corner. It is a really supportive place. I am glad you found us, but sorry you need us.
Usually there is NOT withdrawal from medications for ADHD. My oldest was on many of them. Your insurance wants you to try the generics before they will OK the others. This is pretty common. You do NOT need to try them for 30 days. CALL THE doctor and tell them about her reaction - this is a BAD reaction and the medication needs to be changed. The doctor can now tell United that she cannot tolerate this medication, she needs the other one.
The insurance may demand another generic. It isn't a bad idea to try them, but if this is her reaction then she needs to be changed.
Have they evaluated her for anything else? Often we find that our "ADHD kids" have other problems or have something else. It sounds like you are at the beginning of hte journey and are getting some helpful info.
We do have an insurance forum, they may be helpful with this. Also the Special Education forum can help you with IEP's and other educational things. The people in the forums are just wonderful.
I hope things smooth out soon. Sounds like you have a lot on your hands.
Hugs,
Susie
