What is Strattera?

Strattera is a treatment for attention deficit hyperactivity disorder (ADHD) to help improve attention and reduce hyperactivity and impulsiveness. Strattera works by increasing levels of norepinephrine, a chemical messenger in the brain that is involved in hyperactivity and impulse control. Strattera is usually used together with psychological, educational, and social measures. Strattera is an SNRI medicine that is thought to have it effect by selectively blocking a protein called pre-synaptic norepinephrine transporter.  

Strattera is not a stimulant medication and is not a controlled substance.

Strattera contains the active ingredient atomoxetine, which is from a group of medicines called selective norepinephrine reuptake inhibitor (SNRI). Strattera received FDA approval on November 26, 2002, for the treatment of Attention-Deficit/Hyperactivity Disorder. Strattera has not been studied in children less than 6 years old. Strattera generic is now available under the active ingredient name atomoxetine.
