Key takeaways
Strattera (atomoxetine) and Concerta (methylphenidate extended-release) are both medications that treat ADHD (attention deficit-hyperactivity disorder). Concerta is a stimulant medication, but Strattera isn’t. They’re both typically taken once a day. In general, stimulants like Concerta are first-choice options for treating ADHD, while non-stimulants like Strattera are a second-choice option. Stimulants like Concerta start working the day you start taking it. But Strattera takes several weeks to work. Concerta is a controlled substance, but Strattera isn’t. They can both cause nausea, headache, and lowered appetite. Strattera, though, is more likely to cause dry mouth and constipation.
