Why is 20 mgs of zyprexa doing nothing for my paranoia?

Uncertain: However, we don't know if this is paranoia that is part of your normal personality, a paranoid delusion or a symptom of a thought disorder (like schizophrenia). Each may respond quite differently. Hopefully you are also receiving psychotherapy. Take care.

Why: That's a big question. Usually that's a very effective med for the right patient. Work closely with your doctor to ensure the diagnosis and full treatment regimen is best for you.
