Medicine choices

Several medicines are used to treat bipolar disorder. It may take time to find the treatment that works best for you. The most common medicines used are:

• Mood stabilizers, such as lithium (Lithobid). Experts believe that lithium may affect certain brain chemicals (neurotransmitters) that cause mood changes. A mood stabilizer and an antipsychotic are recommended as the first medicines for acute manic episodes.
• Anticonvulsants, such as carbamazepine (such as Equetro and Tegretol), divalproex (Depakote), and valproate (Depakene). They are also considered mood stabilizers. Divalproex and valproate are used to treat manic episodes. The anticonvulsant lamotrigine (Lamictal) may be helpful for bipolar depression.
• Antipsychotics, such as aripiprazole (Abilify), olanzapine (Zyprexa), quetiapine (Seroquel), risperidone (Risperdal), and ziprasidone (Geodon). Antipsychotics improve manic episodes. Olanzapine may be used in combination with other medicines.
• Benzodiazepines, such as diazepam (Valium). These may be used instead of antipsychotics or as an additional medicine during a manic phase.
