Hi my 5 yo son is on Methamphetdate (can’t spell that for the life of me sorry. The generic Ritalin long acting). He was diagnosed at 4 yoa. We also have him on Tenex (not sure the dose as of right now). It works for impulse control at school. Just starting a second dose for home.
I was diagnosed almost 35 years ago when I was 5 with ADHD and an LD. I wouldn’t be where I am today without meds. I’ve been on Ritalin, Adderall and no Vyvanse. Meds are a good place to start, but also getting help from a mental health DR (psychiatrist and psychologist) is key as well.
I hope my info that I provided helped. Best of luck!
