Key takeaways
Armodafinil (Nuvigil) and Adderall (dextroamphetamine/amphetamine salts) are both medications used to treat narcolepsy, a condition that causes excessive daytime sleepiness. However, they belong to different medication classes and have distinct uses and effects. Armodafinil is a wakefulness-promoting agent, while Adderall is a stimulant. Armodafinil is also used for shift work disorder and obstructive sleep apnea, whereas Adderall is primarily used for attention deficit-hyperactivity disorder (ADHD) and narcolepsy. Armodafinil is taken once daily, while Adderall may need to be taken multiple times a day due to its shorter duration of action. Both medications are available in generic forms, which can be more affordable. Common side effects of armodafinil include headache, nausea, and dizziness, while Adderall can cause trouble sleeping, loss of appetite, and nervousness. Armodafinil has a lower risk of abuse compared to Adderall, which is a Schedule II controlled substance with a higher potential for misuse and dependency. Additionally, armodafinil can interact with hormonal birth control, while Adderall can interact with medications affecting serotonin levels.
