Before the Vyvanse he was on Adderall. He switched to Vyvanse because the Adderall showed increased impulsivity and sometimes aggressive behavior. The foot issue started with the Vyvanse so we went with the same medication as Foccalin. Yesterday the foot issue started up again. So his doctor is clueless as to what to prescribe him. The teachers at school call me to discuss his behaviors almost daily. It really saddens me to see him like this.
