Attention-deficit hyperactivity disorder (ADHD) is estimated to affect 4.4% of adults in the U.S. Adults with ADHD have more problems with work, family relationships and social interaction, are more likely to smoke and use drugs, and have a significantly lower quality of life. One study found that 29.3% of adults with ADHD also have social anxiety disorder making it the most common anxiety disorder in people with ADHD. The treatment of ADHD often involves stimulants such as Ritalin, but it is unclear how this would affect people who also have social anxiety disorder. Atomoxetine has been found to be effective in adults with ADHD, adults with ADHD and alcohol problems, and children and adolescents with ADHD and anxiety disorders. A team of researchers in the U.S. studied the effectiveness of atomoxetine for adults with ADHD and social anxiety in a study of 442 people. They found that, compared to a placebo, atomoxetine effectively improved the symptoms of both ADHD and social anxiety and was well tolerated by the participants.
