My 7 year old son has been taking Singulair for about 2 years now. He has suffered from asthma since he was an infant and started with Pulmicort, then Zyrtec, then Singulair with Claritin (adding Albuterol and Flovent during periods of wheezing) as he aged. We have changed meds often due to concerns about staying on a steroid (Pulmicort) and noticible behavior problems (Zyrtec) and were assured by his doctor that Singulair does not have the same side-effects as the others. After reading so many of the other postings on this site, we are pretty certain that his unusual behavior (ADD like attention problems, fits of crying for no reason, inability to explain why he is doing things, acting out, etc.) are possibly the result of the Singulair. Like many others who have posted on this site, my son had always been a sweet well-behaved child who people loved to be around. However, over the past couple of years we have noticed more and more incidents of inappropriate behavior in school and nothing we have tried has worked to resolve the behaviors. He basically annoys others to the point that they avoid being around him and recently classmates have asked his teacher to move them to another table so they do not have to be bothered by him. Yesterday he cried uncontrollably for over 20 minutes when a toddler broke apart a Lego design he had just finished. I am going to stop the Singulair today and see if we notice any improvements over the next few weeks. I know we are at risk of asthma attacks without it (it definitely controls his asthma as he has not had an attack since going on it), but will continue the Claritin and have Albuterol if needed. NO medicine is worth taking if it can have such an impact on a child's behavior! I just hope, if it is the meds that have caused his behavior, that it is reversible after he is off and he will go back to beging the great kid that he used to be.
