Is Singulair linked to suicide? The Food and Drug Administration (FDA) is investigating reports of mood changes, suicidal behavior and even suicide in patients who have taken the popular, best-selling Merck drug. While Merck has recently updated Singulair's side effect list to include tremors, anxiousness, depression and suicidal behavior, the FDA wants a more in-depth data analysis of the possible suicide link.

Merck's top-selling product in 2007, Singulair brought in sales of $4.3 billion and is used by millions. According to a CNNMoney.com Article, Merck officials say there have been no suicides among the 11,000 patients enrolled in trials of Singulair.
