Stuttering worsened with atomoxetine treatment in a child with attention deficit and hyperactivity disorder

Stuttering; is defined as a deterioration in the fluency and timing of speech that can occur at any age, and which is inappropriate to the individual’s age and language skills. Several factors play a role in its etiology. Medications are one such factor. Atomoxetine is a drug that is frequently employed and well- tolerated in the treatment of attention-deficit hyperactivity disorder in children and adolescents. Stuttering is not a common side- effect when using atomoxetine. This report describes, a seven-year-old patient whose stuttering worsened significantly during atomoxetine use. This case is reported due to the scarcity of cases in which stuttering worsened during the use of atomoxetine.
