I have reviewed your query and here is my advice.  Zyprexa use may cause extrapyramidal adverse effects such involuntary movements. These adverse effects are dose dependent, so, if it possible to lower the dose, these adverse effects may settle down. Discuss with the Psychiatrist about these issues.
