ADHD Drugs to Get New Warnings

Feb 21, 2007 | NewsInferno.com

The U.S. Food and Drug Administration (FDA) announced today that it is ordering all manufacturers of attention deficit hyperactivity disorder (ADHD) medication to develop Patient Medication Guides to warn patients of potentially serious side effects. The most significant warnings will be related to adverse psychiatric symptoms and to cardiovascular risks.

“Medicines approved for the treatment of ADHD have real benefits for many patients but they may have serious risks as well,” said Dr. Steven Galson, director of the FDA’s Center for Drug Evaluation and Research (CDER). “In our ongoing commitment to strengthen drug safety, FDA is working closely with manufacturers of all ADHD medicines to include important information in the product labeling and in developing new Patient Medication Guides to better inform doctors and patients about these concerns.”

According to the agency, “An FDA review of reports of serious cardiovascular adverse events in patients taking usual doses of ADHD products revealed reports of sudden death in patients with underlying serious heart problems or defects, and reports of stroke and heart attack in adults with certain risk factors. Another FDA review of ADHD medicines revealed a slight increased risk (about 1 per 1,000) for drug-related psychiatric adverse events, such as hearing voices, becoming suspicious for no reason, or becoming manic, even in patients who did not have previous psychiatric problems.”

In May of 2006, the FDA’s Pediatric Advisory Committee and the Drug Safety and Risk Management Advisory Committee directed the drug makers to revise their label warnings, and the new directive for Patient Medication Guides is the next step in that process. There are 15 medications subject to the new warnings: Adderall, Adderall XR, Concerta, Daytrana, Desoxyn, Dexedrine, Focalin, Focalin XR, Metadate CD, Methylin Oral Solution, Methylin Chewable Tablets, Ritalin, Ritalin SR, Ritalin LA, and Strattera.

The FDA says that approximately 3 percent to 7 percent of children and 4 percent of adults suffer from ADHD, which has three main symptoms: inattention, hyperactivity, and impulsivity. They recommend that any patient considering using any of these drugs “develop a treatment plan that includes a careful health history and evaluation of current status, particularly for cardiovascular and psychiatric problems (including assessment for a family history of such problems).”

According to drafts of the medication guides posted on the FDA’s website, the warnings include information about adverse events including “heart-related problems” and “mental (psychiatric) problems.” The heart-related problems cited include sudden death in patients who have heart problems or heart defects; stroke and heart attack in adults; and increased blood pressure and heart rate. The psychiatric problems facing all patients include new or worse behavior and thought problems; new or worse bipolar illness; and new or worse aggressive behavior or hostility. For children and teenagers, there are added warnings about new psychotic symptoms (such as hearing voices, believing things that are not true, unfounded suspicion) or new manic symptoms.
