Vyvanse (lisdexamfetamine) typically takes about 1 to 2 hours to start working after ingestion. Its effects can last for up to 14 hours, depending on the individual and the dosage. Factors such as metabolism, whether it’s taken with food, and individual sensitivity to the medication can influence how quickly it takes effect. Always consult your healthcare provider for personalized information regarding medication.
