I have a 2 1/2 year old daughter who was put on Singular about 3 months ago. About a week after taking it she began to break out in hives. Has anyone else observed this in their child? I took her to an allergist who ran all kinds of tests and they said that she was allergic to nothing. I am taking her off of it to see if the hives go away. She is also very moody, cries all the time, is very aggressive. She was never like that until she began taking this drug. Of course, the allergist said it was not Singular, and for me to continue giving it to her.
