Drugs said to boost suicide risk in young

Using antidepressants increases the risk of suicidal thoughts and behavior among people 18 to 25 but lessens it for those who are older, the Food and Drug Administration said.

The effects of antidepressants on adults ages 25 to 64 were mixed, so much so that the FDA would conclude only that the drugs had a neutral effect on suicidal behavior for them.

The information came from a review of 372 studies involving 100,000 patients and 11 drugs, including Lexapro, Zoloft and Prozac. The FDA analysis will be incorporated in future changes to antidepressant labels.
