Strattera is a prescription medication used to treat Attention Deficit Hyperactivity Disorder (ADHD) in children, adolescents, and adults. Unlike stimulant medications, it contains the active ingredient atomoxetine, which works by increasing levels of norepinephrine in the brain, helping to improve focus and reduce impulsivity. Strattera is taken orally, usually once or twice a day, and can be prescribed for individuals who may not respond well to stimulants or prefer a non-stimulant option. Common side effects may include stomach upset, fatigue, and changes in appetite, but it is generally considered safe when used as directed by a healthcare professional.
