On Thursday, the Food and Drug Administration announced that they are conducting a probe into the popular allergy medication Singulair because it allegedly causes depression and leads to risk for suicides. If I recall, several other drugs have lead to investigations for similar risks. Accutane comes to mind. Has anyone taking Singulair experienced these types of symptoms?

THURSDAY, March 27 (HealthDay News) -- The U.S. Food and Drug Administration said Thursday it was investigating the possibility of an increased risk of mood changes and suicidal behavior among those who take the highly popular asthma drug Singulair.

Singulair is the number one-selling drug among people aged 17 and younger. Last year, it posted sales of $4.3 billion, making it Merck & Co.'s top-selling product, according to the Associated Press.

In issuing its statement, the FDA stressed that asthma patients should not stop taking Singulair without talking to their doctor first.
