<s>[INST] My brother took too much of his Vyvance (ADHD medication) two days ago. He said he was very very anxious and freaking out, but the side effects are gone. But it has been almost 48 hours since he has taken the meds and he says his head feels weird, like mentally. He suffered fom a pretty bad case of depression about 5 years ago, and i am worried this has triggered it again. Can you give me any advise on what he needs to do. [/INST] His had gone through your query. ADHD means attention deficit hyperactive disorder can be treated with multi modality approach.Vyvanse is amphetamine derivatives and nowadays it is not a choice in ADHD. It is psycho stimulant can cause many mental disturbances including psychosis and hallucinations. So Go for better alternative is good treatment. There are many alternatives like methylphenidate, clonidine etc. So discuss with treating doctor and get advise. Thank you. </s>
