Thing to know about vyvanse


Vyvanse (lisdexamfetamine) is a is central nervous system stimulant drug used in

the treatment of attention deficit hyperactivity disorder (ADHD) in adults and

children. It is approved for use against ADHD by the U.S. Food and Drug

Administration in July 2007. Vyvanse is also approved in treatments of binge eating

disorder (consuming a large amount of food without having the urge to stop) in

grownups. When using Vyvanse for treating ADHD, it acts on the central nervous

system by boosting the levels of the dopamine and norepinephrine chemicals in the

brain leading to a more focused and attentive mindset and reducing the impulsive

and hyperactive disorder.

Vyvanse is a drug that takes one to two hours before affecting the body after use and

can last for about 14 hours before the effects stop. This feature makes the Vyvanse

drug difficult to be an abused drug compared to other CNS stimulants but may be

abused when taken beyond the prescribed dosage. Vyvanse can be taken with or

without eating in a prescribed dosage. The drug is usually prescribed in 10mg, 20mg,

30mg,40mg,50mg, 60mg, and 70mg, and children’s prescriptions are usually the

30mg dosage strength.


Vyvanse should not be taken if the patient is experiencing conditions like heart

diseases, severe high blood pressure, hyperthyroidism, glaucoma, and high state of

anxiety, tension, and agitation. And it should not be taken by patients who are

allergic to stimulus drugs.

Since all drugs used for fighting ADHD are not proven to be either safe or harmful

for pregnancy, it is advised to not use Vyvanse during pregnancy.
