Yes: Stelazine is a first generation antipsychotic medication. It is effective in controlling the psychosis as seen in schizophrenia. As you indicated, trifluoperazine is the generic name for stelazine. The first generation antipsychotic medications tend to have more side-effects then the second generation antipsychotics. This may especially apply to the side-effect called tardive dyskinesia.

MEDICATION: It's important to find the correct combination of medications with your Psychiatrist. Medications aren't sufficient since they don't teach you coping mechanisms. A Clinical Psychologist with expertise in multiple types of psychotherapy can help you find ways to handle stress that will help medications work better.
