Dr. Glen Elliott answered

Specializes in Child Psychiatry

Try more: If you are truly having neither benefit nor side effects, then try more, up to 70 mg. It is an unusual medication in psychiatry--the only prodrug. It is inactive until absorbed and then cleaved into lysine and amphetamine. As a result, dosage requirements compared to other stimulants can be impossible to guess in advance.
