Re “Drowned in a Stream of Prescriptions” (front page, Feb. 3):

Attention deficit hyperactivity disorder is a real illness that affects millions of children, adolescents and adults. Without treatment, it can have significant consequences, including problems in school and an increased risk of accidents, injury and substance abuse.

Fortunately, effective treatment is available. A comprehensive evaluation is the crucial first step in determining whether someone has the disorder. Medication can help, as part of a comprehensive plan overseen by a responsible and qualified physician.

The majority of people who take medication for A.D.H.D. do not experience serious adverse effects. All interventions have both risks and benefits. Patients and families need to ask questions and feel empowered to get a second opinion. No one has all the answers, and no single course of treatment is right for all patients.

The abuse of prescription drugs is a serious problem. Child psychiatrists will continue to educate our patients and their families about the importance of taking medication only as prescribed and about reporting any changes in symptoms or potential adverse effects.
