Lisdexamfetamine is a prescription medication primarily used to treat Attention Deficit Hyperactivity Disorder (ADHD) in children and adults. It is a prodrug, meaning it is inactive until metabolized in the body, which helps to reduce the potential for misuse. Lisdexamfetamine works by increasing the levels of certain neurotransmitters in the brain, improving focus and attention. The medication is typically taken once daily in the morning and comes in capsule form. Common side effects may include decreased appetite, insomnia, and dry mouth. It is important for patients to follow their healthcare provider's instructions and report any concerning symptoms while using lisdexamfetamine.
