WOW!!! I am glad I came across this website. I have twin boys that will be 7 this month. One has been on Singulair for about 3 years for allergy induced asthma and my other son has been on it for 9 months for allergies. I am taking them both off of it today. The son that is taking the medicine for 3 years has become increasingly angry and gets upset over small things. Over Memorial weekend, he lost a game he was playing on the wii and exploded. He was banging his head and then started to hit me. NEVER in my life have I seen him attack anyone. A few days later he threw rocks at his friend because he wanted the wagon. Over the past 3 years I have noticed some change in him and just took it as growing pains. He has always been a strong will child. However, over the past 3 years he has gotten worse and since he has physically attacked me and his friend, I have decided to send him to counseling. Now I firmly believe it is the Singulair.
My other son has been on it since August. He started to have anxiety within a month of taking it. His behavior has been stressed, depressed and not wanting to play with other kids. He was biting his nails to a nub, licking his hands, not talking to anyone at school and rubbing his head. I have also noticed he does like to look at the person he is talking too. Of course I thought the worse and thought he was being molested. I went to his Teacher and she has worked very hard with him, but he is still a loner. If you knew him before, he played with everyone and enjoyed life. I was told by his Ped. that he had anxiety and to have him see a shrink.
I am hoping that after taking them both off this medicine, I will see improvement.
