FDA Asks Antidepressant Makers To Warn Young Adults About Suicide Risks

WASHINGTON (AP) _ Young adults beginning treatment with any antidepressant should be warned about an increased risk of suicidal thoughts and behavior associated with the drugs, health officials said Wednesday.

The Food and Drug Administration proposed labeling changes that would expand a so-called ``black box'' warning now on all antidepressants. It would broaden the severe warning's current language, which applies only to children and adolescents, to include adults 18-24 during the first month or two of treatment with the drugs, the FDA said.

Eli Lilly and Co., the maker of Prozac, Zoloft manufacturer Pfizer Inc. and other pharmaceutical companies said they would comply with the FDA request.

The proposed labeling changes also would note that studies have not shown this increased risk in adults older than 24, and that adults 65 and older taking antidepressants have a decreased risk of suicidal thoughts and behavior.

The expanded warnings would emphasize that depression and certain other serious psychiatric disorders are themselves the most important causes of suicide.

``Antidepressant medications benefit many patients, but it is important that doctors and patients are aware of the risks,'' said Dr. Steven Galson, the FDA's drugs chief.

The FDA advises that patients of all ages starting on antidepressants should be ``monitored appropriately and observed closely'' for worsening symptoms, suicidal thoughts or behaviors or unusual changes in behavior.

Still, any risks are small: for every 1,000 patients 18-24 treated with antidepressants, the FDA would expect there would be five additional patients who have suicidal thoughts or exhibit suicidal behavior, said Dr. Thomas Laughren, who oversees psychiatric drugs for the FDA. The FDA analysis was based on studies of 11 antidepressants in more than 77,000 patients.

The proposed changes came with the endorsement of FDA expert advisers. Some experts have argued that the changes are overdue while others maintain they could keep drugs from those who need them.

Last month, a comprehensive analysis of antidepressants for children and teenagers found the benefits of treatment trump the small risk of increasing suicidal thoughts and behaviors in some patients. The Journal of the American Medical Association study also found that risk is lower than what the FDA identified in 2004, the year the agency warned the public about the risks of the drugs in children.

After that warning, doctors wrote children fewer prescriptions for antidepressants, and U.S. youth suicides increased.

That suggests the warnings could have a net effect that is harmful if they keep the drugs from patients who would benefit from them, said Dr. David Brent, a University of Pittsburgh School of Medicine psychiatry professor and co-author of the JAMA study.

``When you have a black-box warning and within it you caution people that the biggest risks are from the disease and not being treated, people will still pay attention to the headline and not the small print,'' Brent said.

Laughren said the FDA's doesn't know if the previously strengthened warnings led to the decrease in prescriptions or the increase in youth suicides.

``These are data that are hard to reach any conclusion about in terms of causality, but obviously it is something we are concerned about,'' Laughren said.
