Has her doctor ever checked into DNA testing to find what medications she can best metabolize? Some insurance pays for testing. Check first.
I found out my Difficult Child didn't have a specific enzyme for some medications...and twice as many of one enzyme so she metabolized it too fast and it didn't stay in system long enough to help.
Our report had 3 lists of medications to try...one that was recommended, and the other lists to use with caution or extreme caution.
