Lisdexamfetamine: What You Need to Know About This ADHD Medication
Lisdexamfetamine is a prescription stimulant used to treat ADHD and binge eating disorder. Learn how it works, what to expect, and what matters before you start.

How it works
Lisdexamfetamine is a prodrug, meaning your body converts it into its active form (dexamphetamine) after you take it. This delayed activation can reduce the potential for misuse compared to medications that work immediately.

- ADHD symptoms in people aged 6 and older
- Binge eating disorder in adults
What to expect
Most people taking lisdexamfetamine notice improved focus and attention within 1 to 2 hours. Effects typically last 10 to 12 hours. Your doctor will start with a low dose and adjust based on your response and tolerance.
Side effects
Common side effects include decreased appetite, sleep problems, elevated heart rate, and anxiety. Serious side effects are rare but can include chest pain, severe headaches, or unusual changes in mood.
Before you start
Tell your doctor if you have a history of heart problems, high blood pressure, mental health conditions, or substance use. Lisdexamfetamine can interact with other medications, so provide a complete medication list.
Cost and access
