My daughter, now 7 years old, took Singulair (4mg crystals) every evening from 12/29/2004-4/3/2008 (with 5 days off in 2/2008 ONLY). She developed significant mood disturbance/mood swings, sleep disturbance/frightening dreams and anxiety/unexplainable fears during this time, which we have now attributed to the drug, Singulair - the ONLY MEDICATION SHE WAS TAKING besides occasional antihistamines (which caused no problem). The drug Singulair clearly caused significant psychiatric symptoms in my daughter which are strikingly similar to symptoms now being attributed to the drug by MANY parents across the country. I suspected Singulair of negatively affecting my daughter and talked to her allergist about taking her off it in 2/2008 (before any news broke about links between Singulair and suicidal thoughts/behavior). The effects of Singulair on the brains of children are NOT UNDERSTOOD and/or NOT reported. I believe that this is a dangerous drug. It has been very difficult to connect the use of this asthma/allergy drug to behavior/mood issues in young children for two reasons. First, improperly trained physicians confuse drug "side effects" with normal child development (a "phase") or psychiatric illness. Second, Singulair has been heavily marketed as "SAFE" (to the medical community and directly to patients and their parents) and therefore has not been suspected when these serious psychiatric disturbances are reported to doctors. Pediatricians and allergists have said for years, "It couldn't be the Singulair" because that is the impression SOLD to them by Merck.
