How long does 240 mg of Vyvanse stay in system?

Vyvanse (lisdexamfetamine) has a half-life of approximately 10 to 13 hours, meaning it takes this amount of time for half of the drug to be eliminated from the body. Generally, Vyvanse can be detected in the system for about 1 to 3 days after consumption, depending on factors like metabolism, dosage, and frequency of use. For a dose of 240 mg, it may take longer for the body to completely clear the drug, but individual variations will affect the exact duration. Always consult a healthcare professional for personalized information.
