In general, stimulants like Adderall are first-choice options for treating ADHD, while non-stimulants like Strattera are a second-choice option. Adderall starts working the day you start taking it. Strattera takes several weeks to work. Stimulants like Adderall are controlled substances, which means they can both lead to dependence and misuse. Strattera isn’t a controlled substance.
