2.1 General Instructions for Use
Take Vyvanse in the morning with or without food; avoid afternoon doses because of the potential for insomnia. Vyvanse may be administered in one of the following ways:
- Take Vyvanse capsules whole, or
- â€‹Open capsules and empty and mix the entire contents in a glass of water. If the contents include any compacted powder, a spoon may be used to break apart the powder in the water. The content should be stirred until completely dispersed. Consume the full glass of water immediately. It should not be stored. The active ingredient dissolves completely once dispersed; however, a film containing the inactive ingredients may remain in the glass once the water is consumed. Do not take anything less than one capsule per day, and a single capsule should not be divided.
2.2 Dosing Information
â€‹The recommended starting dose is 30 mg once daily in the morning in patients ages 6 and above. Dosage may be adjusted in increments of 10 mg or 20 mg at approximately weekly intervals up to maximum dose of 70 mg/day. Patients may be maintained on their optimal dose [see Clinical Studies (14)].
2.3 Important Information Prior to Dosing
â€‹Prior to treating children, adolescents, and adults with CNS stimulants, assess for the presence of cardiac disease (e.g., a careful history, family history of sudden death or ventricular arrhythmia, and physical exam) [see Warnings and Precautions (5.2)].
â€‹To reduce the abuse of CNS stimulants including Vyvanse, assess the risk of abuse, prior to prescribing. After prescribing, keep careful prescription records, educate patients about abuse, monitor for signs of abuse and overdose, and re-evaluate the need for Vyvanse use [see Warnings and Precautions (5.1), Drug Abuse and Dependence (9.2, 9.3)].
2.4 Dosage Modifications due to Drug Interactions
â€‹Agents that alter urinary pH can impact urinary excretion and alter blood levels of amphetamine. Acidifying agents (e.g., ascorbic acid) decrease blood levels, while alkalinizing agents (e.g., sodium bicarbonate) increase blood levels. Adjust Vyvanse dosage accordingly [see Drug Interactions (7.1)].
