[|Human|] my son 12 years old he has been on vyvasnse 50mg for 6 years he has been digging at his head off and on for 2 years  he is not growing very good he is almost 13 weights 84 pounds and 52inches tall, we had to shave his head because he pulled his hair  out in places where is smooth down to his scalp and he says he cant help it we dont know what to do is it the vyvanse causing this.
[|AI|]  HiT hanks for using Chat Doctor His weight is normal according to age and height. His BMI is 22, so there is nothing to worry about it. With time, he would catch his growth. I think, he has trichotillomania. In that case, he has impulse to pull his hair out. He needs few antidepressants to control this. Some stimulant like Vyvanse could cause trichotillomania. Better to consult a psychiatrist for proper treatment. Thanks
