Is there an alternate to methylphenidate to cure/control adhd in a 5 year old child, who also has mild autism and 2 instances of epileptic seizures?

MPH has a slight : Risk of lowering the seizure threshhold. Start with a very low dose of vyvanse; it often causes fewer side effects than its active ingredient, Adderall xr. 20 mg. Of vyanse = ~ 6.5 mg. Of Adderall xr. Onset of action is 2 hrs.; duration is 12-14 hrs. Intuniv 1mg. Or strattera (atomoxetine) 10 mg. With very slow titration works in ~ 4-6 wks., when a low-dose stimulant often can be added without side effects.

Nonstimulants: With a history of seizures in a child so young, nonstimulant medications such as intunive or stratera may be worth discussing with your doctor.

Several alternatives: Among the alternatives are amphetamines (adderall, vyvanse) Provigil and nuvigil. these are not likely to cause a recurrence of seizures but are efficacious in treating ADHD
