• Watch for these changes and call your healthcare provider right away if you notice:
  • New or sudden changes in mood, behavior, actions, thoughts, or feelings, especially if severe.
  • Pay particular attention to such changes when fluoxetine is started or when the dose is changed.

Keep all follow-up visits with your healthcare provider and call between visits if you are worried about symptoms.
