ADHD
"The Actavis generic version of this medication was worse than useless, as all of the ADHD hyperactive subtype symptoms my son was experiencing returned within a week of switching to this from the Intuniv ER brand (daily 2mg dose), along with new and potentially dangerous side-effects.  His symptoms had been well-controlled for years prior to the insurance company insisting that we try a generic before they would continue to cover the cost of the brand."
