Vyvanse Overview

Vyvanse is a prescription medication primarily used to treat attention deficit hyperactivity disorder (ADHD). It belongs to a class of drugs known as stimulants, which work by affecting certain chemicals in the brain.

How Vyvanse Works

Vyvanse contains the active ingredient lisdexamfetamine, which is a prodrug. This means it is inactive until it enters the body, where it is then converted into dextroamphetamine, a central nervous system stimulant. Dextroamphetamine increases the levels of certain neurotransmitters, such as dopamine and norepinephrine, which play a crucial role in attention and impulse control.

Neurotransmitter Effects

  • Dopamine: Increased dopamine levels can enhance focus and attention.
  • Norepinephrine: This neurotransmitter helps regulate alertness and arousal.

Vyvanse’s precise mechanism helps individuals with ADHD better manage their symptoms, but it can also lead to side effects, including fatigue.

Possible Side Effects of Vyvanse

Vyvanse, like any medication, can have side effects. It’s essential to be aware of these potential issues when considering its use.

Common Side Effects

Common side effects of Vyvanse include insomnia, loss of appetite, and increased heart rate. These effects are typically mild and tend to improve over time.


  • Sleep Disturbance: Some individuals may experience difficulty falling asleep or staying asleep while taking Vyvanse.
