Yes. Trifluoperazine is an antipsychotic that can be used to treat bipolar disorder especially when there are psychotic symptoms present or when it is added to a mood stabilizer like lithium. Newer medications are available that seem to be better tolerated.
Stelazine. Stelazine (Trifluoperazine) is a first-generation antipsychotic used to treat schizophrenia. It would not be my first choice to treat a bipolar patient with psychotic features. An atypical antipsychotic would be perferrable.
