From the Research

Managing mania in a patient already taking Prozac (fluoxetine) and Wellbutrin (bupropion) requires immediate intervention, and the most effective approach is to add a mood stabilizer such as lithium or valproate, or an atypical antipsychotic like olanzapine or risperidone, as evidenced by the study 1. The first step is to contact a psychiatrist for urgent evaluation while temporarily discontinuing or reducing the Wellbutrin and potentially the Prozac under medical supervision. Some key points to consider in managing this condition include:

  • The potential for antidepressants like Prozac and Wellbutrin to trigger or worsen mania in susceptible individuals, particularly those with bipolar disorder, as noted in the study 2.
  • The importance of adding a mood stabilizer or an atypical antipsychotic to control the manic episode, with options including lithium (600-1200 mg/day), valproate (750-1500 mg/day), olanzapine (5-20 mg/day), or risperidone (2-6 mg/day), as supported by the study 1.
  • The use of benzodiazepines like lorazepam (1-2 mg every 4-6 hours as needed) for acute management of agitation, while the mood stabilizer takes effect.
  • The need for regular monitoring of medication levels, side effects, and mood symptoms for ongoing management, considering the patient's response to treatment and potential risks associated with medication use, as discussed in the study 3.
  • The possibility that the manic episode may indicate previously undiagnosed bipolar disorder rather than unipolar depression, highlighting the importance of thorough diagnostic evaluation and treatment planning, as emphasized in the study 4. Once the acute mania resolves, the treatment plan should be reassessed, potentially maintaining the patient on mood stabilizers long-term while carefully evaluating whether antidepressants should be reintroduced, taking into account the latest evidence and guidelines for managing bipolar disorder, such as those discussed in the study 5.
