The American Lung Association (ALA) sponsored a recent study that sought to determine a true link between Singulair, a common medication used to treat allergies and asthma, and suicidal thoughts or tendencies. The original concern for a link between Singulair and suicide was announced by the Food and Drug Administration in March 2008 after there were several reports of people attempting suicide while taking Singulair.

This new study reassessed the emotional well-being of 569 people taking Singulair in three previously performed studies, and found no evidence of emotional distress in neither adults or children taking Singulair. In fact, because Singulair is known to treat allergies and asthma, people taking Singulair actually had improvement in their emotional well-being.

The FDA has yet to comment, and I would personally be surprised if the FDA would agree with this study that there is no evidence for a link between Singulair and suicide.
