FDA approves ADHD drug for binge-eating disorder

WASHINGTON — Federal health regulators have approved an attention deficit disorder drug for a new use: a first-of-its kind treatment for binge-eating disorder.

About 2 percent of U.S. adults, or about 5 million people, have binge-eating disorder, according to the Department of Health and Human Services.

Standard treatment for binge eating and other eating disorders usually involves counseling and psychotherapy. Some doctors also prescribe antidepressants to try and curb eating disorders, though they are not approved for that use.

The Food and Drug Administration originally approved Vyvanse in 2007 as a once-aday pill for attention deficit hyperactivity disorder. On Friday, the agency cleared the drug for adults who compulsively overeat.

Vyvanse, known chemically as lisdexamfetamine dimesylate, is part of a family of drugs that stimulate the central nervous system.

The drug’s prescribing label warns that Vyvanse has a “high potential for abuse and dependence,” and doctors should monitor patients for such signs.

Serious adverse events associated with Vyvanse can include psychiatric problems like hallucinations and mania, as well as heart complications. More common side effects include sleeplessness, increased heart rate, constipation and anxiety.

Regulators approved the new use for binge eating based on two studies in which adults with a history of the eating disorder had fewer instances per week while taking Vyvanse, when compared with those getting a placebo. The drug is not approved for weight loss.
