How effective is Intuniv at treating ADD/ADHD?
About 70 percent of people who take Intuniv get robust benefits, and we don’t know, in advance of taking it, who will respond well. A person has to try the medication. It typically takes a week to find out if it will help. The benefits accrue over time. Twenty percent of people won’t see any benefit and may feel crummy. About 10 percent experience irritability from the first dose. In my experience, the irritability doesn’t wear off, and I tell affected patients to stop taking it.
