How often does a child with ADHD need to take methylphenidate or dexamphetamine?
A. The spacing of doses will also depend on the child. Most children take two or three doses a day at mealtimes. If a child wakes up with severe behavioural problems and need to take a dose straight away and a second dose a couple of hours later for the start of the school day. Further doses may then be more widely spaced during the day. As a general rule, three doses a day is often more effective than two.
