Despite some reports of suicide among people taking certain asthma drugs, a new study finds no increased risk of attempted suicide among children and young adults on the medications. In 2008, the Food and Drug Administration (FDA) said it was investigating reports of mood and behavior changes, suicidal thinking and suicide among people taking asthma medications known as leukotriene modifiers. The drugs include Singulair (known generically as montelukast), Accolate (zafirlukast) and Zyflo (zileuton).
