Teva-Atomoxetine: Uses, Side Effects and Dosage

ABOUT THIS MEDICATION

What TEVA-ATOMOXETINE is used for:

TEVA-ATOMOXETINE is a medicine for the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) in children 6 years of age and over, adolescents, and adults. TEVA-ATOMOXETINE should not be used in children under 6 years of age.

TEVA-ATOMOXETINE is a part of your overall treatment program for ADHD that may include other measures (psychological, educational, and social). Your doctor may also recommend other therapy.

What it does:

TEVA-ATOMOXETINE is a selective norepinephrine reuptake inhibitor medicine that increases the amount of noradrenaline, a natural chemical in the brain. TEVA-ATOMOXETINE may help increase attention and decrease impulsiveness and hyperactivity in patients with ADHD.

TEVA-ATOMOXETINE works differently from other medicines used for the treatment of ADHD. Atomoxetine hydrochloride is not a stimulant and is not addictive.

What is ADHD:

ADHD has 3 main types of symptoms: inattention, hyperactivity, and impulsiveness. Symptoms of inattention include not paying attention, making careless mistakes, not listening, not finishing tasks, not following directions, and being easily distracted.

Symptoms of hyperactivity and impulsiveness include fidgeting, talking excessively, running around at inappropriate times, and interrupting others. Some patients have more symptoms of hyperactivity and impulsiveness while others have more symptoms of inattentiveness. Some patients have all 3 types of symptoms.

Symptoms of ADHD in adults may include a lack of organization, problems starting tasks, impulsive actions, daydreaming, daytime drowsiness, slow processing of information, difficulty learning new things, irritability, lack of motivation, sensitivity to criticism, forgetfulness, low self-esteem, and excessive effort to maintain some organization. The symptoms shown by adults who primarily have attention problems but not hyperactivity have been commonly described as Attention-Deficit Disorder (ADD).

Many people have these symptoms from time to time. However, people with ADHD have these symptoms most of the time. Symptoms must be present for at least 6 months to be certain of the diagnosis. In addition, the symptoms cause problems in more than one area of life (home, school, work, or social situations).
