Dear Bethany Seed, Welcome to Healthcaremagic!
Citalopram is an antidepressant-- antidepressants are NOT used for bipolar as they will destabilise the disease course.
Trifluoperazine is an older antipsychotic-- may be used but not FDA approved for
bipolar disorder. Moreover, may cause serious side effects if used in long term.
Drugs for bipolar are:
Lithium
Anticonvulsants like divalproex, lamotrigine,
carbamazepine
IInd gen. antipsychotics like olanzapine, quetiapine,
risperidone etc.
