I have a 5 year old son that has been on Singulair for 2 years and when he first began it at 3 I noticed him having attention problems (zoning out). Now at 5 we ask ourselves regularly if other 5 year olds have the mood problems that he has. One minute he can be showing off and happy and the next he's yelling at us all to shut up to him. I am doing the same as you, last night was definately his final dose!
It definitely is worth taking them off to see if the behaviors subside. I teach and I was devastated to recognize some Oppositional Defiant Behaviors in my son at age 3. I was starting to prepare myself to go down that road if his behaviors didn't improve. He is such a sweet, loving and fun child other than the mood swings and rages. I will let you know how it goes for us!
I too am taking my son off of sigulair...he has become downright violent, this is very unlike him. I will post in a few days and let all know the results.
As of today, NO MORE SINGULAIR
After about a month of no singulair, our 3-year old son has had fewer mood swings and rages. When he does get upset, he is consolable and he comes around faster. He is also getting great relief from loratadine for his allergies. It was a good decision for our son and our family.
After about one month of no singulair, I think I can state that our 3-year old son has had fewer mood swings and fits of rage. When he does get upset, he is consolable and he comes out of it faster. His allergies seem to be managed just fine by loratidine, so it was a good decision for us to take him off the singulair
