Ritalin vs. Dexamphetamine: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 17, 2024
Ritalin is a brand name for methylphenidate, a stimulant used to treat ADHD and narcolepsy, while dexamphetamine is a form of amphetamine used for similar purposes but with different pharmacological effects.

Key Differences

Ritalin, chemically known as methylphenidate, works by increasing dopamine and norepinephrine in the brain. Dexamphetamine, a form of amphetamine, also increases these neurotransmitters but through different mechanisms.
Both Ritalin and dexamphetamine are used to treat ADHD and narcolepsy. Ritalin is often preferred for children, while dexamphetamine may be more effective for adults in some cases.
Ritalin can cause insomnia, appetite loss, and headache. Dexamphetamine has similar side effects but may also include a higher risk of dependency and potential for abuse.
Ritalin typically has a shorter duration of action, usually around 3-4 hours. Dexamphetamine's effects can last up to 12 hours, making it suitable for prolonged symptom control.
Ritalin is one of the most commonly prescribed medications for ADHD in children. Dexamphetamine is also widely prescribed but may be more common in adult ADHD treatment.
