Singulair and Possible Suicide Risk
Sunday, March 30th, 2008Singulair is a prescription drug manufactured by Merck & Co. that is used as maintenance treatment for those suffering from asthma, but also used to relieve symptoms of those suffering from seasonal allergies. With millions of asthma sufferers worldwide, Singulair has been touted as a drug that can help prevent the symptoms of asthma before they even start. Over 50 million Americans alone suffer from nasal allergies and Singulair has been helpful in preventing those symptoms as well. It was approved for treating asthma in 1998 and for seasonal allergies in 2003. Singulair is used by millions and resulted in $4.3 billion in sales last year for Merck. It has been prescribed by physicians to both adults and children over the age of two.
However, the Food and Drug Administration (FDA) is looking into a connection between Singulair and suicidal behavior. The FDA called the possible connection an “emerging safety issue” after it was reported to them that “3 or 4” patients who were taking Singulair committed suicide. Currently, the FDA is doing an investigation to see if there is a link between taking Singulair and experiencing extreme mood or behavior changes, including suicidal behavior.
Within the past year, Merck has told physicians that possible side effects of Singulair could be tremors, depression, suicidal thinking or behavior and anxiety. The FDA has asked Merck to look at study data for more information on the patients who experienced depression, suicidal thinking or behavior, but it may take up to nine months for such an evaluation to be completed.
Until the study is complete, the FDA is not recommending that patients stop taking Singulair, but rather talk to their physicians if they have concerns. The FDA also advised physicians to monitor all patients taking this medication as well as Zyflo and Dey, two other drugs in the same class as Singulair. Merck officials issued a statement saying that the FDA based its concerns about Singulair on reports, not clinical findings, which is what is normally used to test drug safety. Of the 11,000 patients that have enrolled in 40 Singulair trials, Merck points out that none have committed suicide.
