Key takeaways
Ritalin (methylphenidate) and Adderall (mixed amphetamine salts) are stimulant medications that treat ADHD (attention deficit-hyperactivity disorder) and extreme sleepiness from narcolepsy. They’re different types of stimulants: Ritalin is a methylphenidate and Adderall is an amphetamine. Both medications are usually taken a few times a day. They also both come in long-acting forms that are taken once daily. There are more dosage forms of Ritalin available than Adderall. Both medications are controlled substances that can cause dependence and misuse. They have similar side effects, such as lower appetite, mood changes, and trouble sleeping.
