Vyvanse is indicated for the treatment of Attention Deficit/Hyperactivity Disorder (ADHD) in adults and pediatric patients 6 and older. Pediatric patients with ADHD younger than 6 years of age experienced more long term weight loss than patients 6 years and older. Vyvanse is not indicated or recommended for weight loss. Use of other sympathomimetic drugs for weight loss has been associated with serious cardiovascular adverse events. The safety and effectiveness of Vyvanse for the treatment of obesity have not been established.
CNS stimulants, including Vyvanse, other amphetamine containing products, and methylphenidate have a high potential for abuse and dependence. Assess the risk of abuse prior to prescribing and monitor for signs of abuse and dependence while on therapy.

Vyvanse has the following contraindications:
Known hypersensitivity to amphetamines or other ingredients of Vyvanse. Anaphylactic reactions, Stevens Johnson Syndrome, angioedema, and urticaria have occurred.
Use with monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping MAOIs (including MAOIs such as linezolid or intravenous methylene blue), because of an increased risk of hypertensive crisis.

Vyvanse, or lisdexamfetamine dimesylate, is an inactive, water-soluble prodrug of dextroamphetamine, in which d-amphetamine is bonded to l-lysine, a naturally occurring amino acid.

Prior to and during treatment assess for the presence of cardiac disease. Avoid use in patients with known structural cardiac abnormalities, cardiomyopathy, serious heart arrhythmia, coronary artery disease, and other serious heart problems. Sudden death, stroke and myocardial infarction have been reported in adults with CNS stimulants at recommended doses, as well as sudden death in pediatric patients with structural cardiac abnormalities and other serious heart problems while taking CNS stimulants at recommended doses. Further evaluate patients who develop exertional chest pain, unexplained syncope, or arrhythmias while taking Vyvanse.
CNS stimulants cause increases in blood pressure (mean increase about 2-4 mm Hg) and heart rate (mean increase about 3-6 bpm). Monitor all patients for tachycardia and hypertension.

After oral administration, lisdexamfetamine is rapidly absorbed from the GI tract.

Lisdexamfetamine is converted to dextroamphetamine and l-lysine primarily in blood due to the hydrolytic activity of red blood cells.

Dextroamphetamine is a noncatecholamine sympathomimetic amine with central nervous system stimulant activity.

Amphetamines block the reuptake of the catecholamines norepinephrine and dopamine into the presynaptic neuron and increase the release of these monoamines into the extraneuronal space.

The parent drug, lisdexamfetamine, does not bind to the sites responsible for the reuptake of norepinephrine and dopamine in vitro.
The clinical significance of in vitro data is unknown.

In summary, lisdexamfetamine, a prodrug of dextroamphetamine, is rapidly absorbed from the gastrointestinal tract into the circulatory system where it undergoes a conversion to dextroamphetamine primarily in the blood and then passes to the central nervous system.

Exacerbation of Pre-existing Psychosis: Vyvanse may exacerbate symptoms of behavior disturbance and thought disorder in patients with a pre-existing psychotic disorder. Induction of a Manic Episode in Patients with Bipolar Disorder: May induce a mixed/manic episode in patients with bipolar disorder. Prior to initiating treatment, screen for risk factors for developing a manic episode (e.g., comorbid or history of depressive symptoms, or a family history of suicide, bipolar disorder, and depression). New Psychotic or Manic Symptoms: At recommended doses, may cause psychotic or manic symptoms (e.g., hallucinations, delusional thinking, or mania) in patients with no prior history of psychotic illness or mania. Discontinue if symptoms occur.

CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients (monitor weight and height). Treatment may need to be interrupted in patients not growing or gaining weight as expected. Vyvanse is not approved for use in pediatric patients below 6 years of age.
CNS stimulants, including Vyvanse, are associated with peripheral vasculopathy, including Raynaud’s phenomenon. Signs and symptoms are usually intermittent and mild; very rare sequelae include digital ulceration and/or soft tissue breakdown. Careful observation for digital changes is necessary during treatment with stimulants. Further evaluation may be required, including referral.
Increased risk of serotonin syndrome when co-administered with serotonergic agents (e.g., SSRIs, SNRIs, triptans) and CYP2D6 inhibitors, but also during overdosage situations. Discontinue Vyvanse if it occurs and initiate supportive treatment.
