What If I Take an Overdose?

People who take too much Vyvanse may have overdose symptoms that could include the following:
  • Restlessness
  • Shakiness (tremors)
  • Overactive reflexes
  • Fast breathing
  • Confusion
  • Hallucinations
  • Panic
  • Fever
  • Muscle pain
  • An irregular heart rhythm (arrhythmia).
If you happen to take too much, seek immediate medical attention.

How Should the Medication Be Stored?

Vyvanse should be stored at room temperature, away from moisture or heat. The capsules should be kept in an airtight container.
Keep this and all medications out of the reach of children.

What Should I Do If I Miss a Dose?

If you do not take your Vyvanse as scheduled, take your missed dose as soon as you remember in the morning. If you do not remember until the afternoon, skip the dose; taking the medication after morning can cause trouble sleeping at night. Do not take a double dose.
