Although you have not mentioned the names of the medicines, from your description it appears that your daughter is suffering from the extra-pyramidal side effects of certain anti-psychotic medicines and later was prescribed an anticholinergic
medicine like trihexyphenidyl
to reduce these adverse effects. Since this helped her only to some extent, you are worried and looking for another doctor. While you are trying to find a more suitable doctor, you can ask your previous doctor to do one of the following:
1) to consider changing her antipsychotic
to one which has lesser risk of extra-pyramidal side effects
2) to lower the dose of the antipsychotic medicine
3) to increase the dose of the anticholinergic medicine prescribed to reduce the side effects
I am sure these steps will benefit her.
