Vyvanse is a brand name for lisdexamfetamine dimesylate, which is a prescription medication that stimulates the central nervous system. Despite its effectiveness for use in treating attention deficit and hyperactivity disorder (ADHD) in children aged six to 12 , Vyvanse poses a risk of side effects.
Types of Side Effects
In children, the most common side effects of Vyvanse include decreased appetite, insomnia, irritability, upper abdominal pain, vomiting and weight loss.
The most common side effects of Vyvanse occur in between 9 and 39 percent of children who take the drug, according to U.S. Food and Drug Administration clinical trials published on rxlist.com.
Drugs such as hypertension thiazides and MAOI antidepressants increase the risk of side effects from Vyvanse.
Vyvanse has the potential to be habit-forming in children, and if discontinued suddenly causes symptoms of withdrawal, including fatigue and depression. In rare cases, withdrawal from Vyvanse leads to psychosis or symptoms similar to schizophrenia.
In children with undiagnosed heart defects, Vyvanse has the potential to cause heart attacks or sudden death, according to rxlist.com. Other risks to children associated with Vyvanse include sudden aggression, seizures, blurred vision, twitches and tics, and growth suppression.
