There are significant differences in the way Modafinil and Adderall, which impacts their side effects and addiction potential.

What Is Modafinil?

Modafinil, often known as Provigil, is a central nervous stimulant medicine that is commonly referred to as a eugeroic treatment, or one that improves alertness and wakefulness. It’s approved by the FDA to treat daytime sleepiness in people who have different conditions, including:

• Narcolepsy

• Shift work disorder is a disorder that involves a disruption of normal sleeping hours when one is working nights

• Sleepiness that occurs in other medical conditions like obstructive sleep apnea Modafinil is a Schedule IV controlled substance by the DEA.

What Is Adderall?

Adderall is the brand name for a drug that contains amphetamine and dextroamphetamine. The FDA has approved this drug combination to treat narcolepsy and attention deficit hyperactivity disorder. Adderall has two main components that activate the central nervous system. 

This drug comes in immediate-release and extended-release forms (Adderall XR). The immediate-release form lasts about 4 to 6 hours, while the extended-release form lasts about 12 hours. Adderall is a Schedule II controlled substance by the DEA for its significant risk of abuse and physical dependence.

Differences Between Modafinil and Adderall

Modafinil has a unique structure and is not a stimulant like Adderall, but it does have stimulant-like effects and improves alertness. It can keep people awake and enhance thinking and perception. Experts aren’t exactly sure how it works, but they have indicated that it enhances several chemicals and neurotransmitters in the brain, such as serotonin, dopamine, glutamate, histamine, and GABA.

Though modafinil does not have major withdrawal effects, each stimulant substance promotes drug usage to some extent, which can lead to dependence and withdrawal. Some people experience decreased energy, lack of motivation, and sadness after discontinuing modafinil, hence it is frequently tapered to limit the risk of withdrawal symptoms. 

This drug is approved by the FDA to treat sleepiness caused by apnea, narcolepsy, or shift work. Off-label, it may be used for multiple sclerosis and Parkinson’s disease, as well as illicitly by students, military, and executives, to combat sleep deprivation and fatigue. Similarly, Adderall is effective for treating people with narcolepsy or ADHD. It stimulates the concentration of dopamine and norepinephrine in the brain, though the exact mechanism of action is not known.
