Vyvance permanent side affects | ADHD Information

We have a 9yr old now from taking her off due to ticking, breathing problems etc now has a permanent motor ticking in the neck. She was started out with too high of a dose @ 50mg & seem to be ok for a short time but we had to take her off due to the side affects & now left with scares  I have never heard of a permanent tic due to meds, but I agree, 50mgs is too high to start. The neck tic could be Tourettes that was exacerbated by the stims? Yes I never herd of this either but she never had this problem before vyvance. She is now set up to get tested. We will let you know what we find out. But I will say, this is the most odd drug I have ever seen, From great to trying to use a knife on some one. I will say that you only have a 40% chance or less of this drug ever working.
