My 3 year old son had severe asthma and had been hospitalized several times. In May of 2007 he was given Singulair for his asthma. It seemed to work well and after his release he was taken off the meds. In October he became ill again and I told the doctor about how well the Singulair had worked. He started Singulair the first week he seemed to be doing great. But by the second week I started having aggressive behavior and became very restless. He was constantly acting out. This was a child who always was so sweet and kind. I started to question his behaviors, but because the medication seem to be working so well with the asthma- I dismissed it. Well by the end of the second week my son got very aggressive with my mom and collapsed and starting having a very violent seizure. He stopped breathing and ER was called. At first we thought the seizure was due to him being sick. He was sent home. The following week my son again had two seizures within 6 hours. This happened again the following week. No one could figure out the problem. I started thinking what had changed in his life over the past few weeks. The only new thing in his life was the Singulair. I started asking about the Singulair and the doctors agreed because the seizure's seems to come within a few hours of him receiving the Singulair medication. Singulair was stopped and the doctors and my family all agreed he was allergic to Singulair. Although the medication has stopped my son is still having the seizures and is now on two seizure medication. I know my son's situation maybe a little more severe than others on this site. I just think that this medication may not be good for children. It seems that it is doing something to the chemical balance in these children's brain. I am no doctor-but I do believe that this medication really needs to be further reviewed. Especially in the use of small children. I am just happy that my son is still alive. Everyone please do your research and be careful and ask questions before placing your child on any medication. Because each person reacts differently to drugs. It's just unfortunate for my son that he went from a child suffering from asthma. And now he is a child suffering with asthma and seizure disorder. And I firmly believe that this medication caused my son's problems.
