Data from several randomized controlled clinical trials indicate that the benefits of Fluoxetine for treating major depressive disorder (MDD) in children and adolescents outweigh its risks. Fluoxetine was reported to have notable effects superior to placebo (formulation without active ingredients, such as sugar pills). Therefore, it is primarily used in children for the following purposes.

  • The acute phase treatment of MDD in child and adolescent outpatients with severe persistent depression (2).
  • The prevention of relapse or extending time to relapse in pediatric MDD (3).
  • Short-term or maintenance treatment of MDD or OCD in children aged eight years and older.

Scientific evidence suggests that Fluoxetine may be the drug of choice for treating MDD and anxiety disorders. However, for use in anxiety disorders in children, approval is restricted to anxiety associated with OCD. Experts believe that the medication should be reserved for patients with moderate to severe depression. Maximum benefit can be derived if the medication is combined with cognitive behavioral therapy (CBT)iAn intervention that aims at changing negative thought patterns and behaviors to manage a mental-health condition with proper monitoring in children and adolescents (4) (5).

Your child’s psychiatrist may recommend CBT along with Prozac for children with mental health conditions to ensure better outcomes.

Also, notify your child’s psychiatrist of any side effects and keep following up on the progress on a regular basis.
