Hi,
Vyvanse is composed of 'Lisdexamfetamine', which is a
substituted amphetamine and an inactive prodrug of the
central nervous system stimulant
dextroamphetamine. It is used in the treatment of attention deficit
hyperactivity disorder and
binge eating disorder.
Side effects include nausea, vomiting, constipation, stomach/abdominal pain, loss of appetite, dry mouth, headache, nervousness, dizziness, trouble sleeping, sweating, weight loss, irritability, and restlessness may occur.
At normal therapeutic doses, the physical side effects of amphetamine vary widely by age and from person to person.
If any of these effects persist or worsen, you need to seek doctor's attention promptly.
It would be better to use this medication for the specified period and the necessary dosage, as prescribed by your doctor.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Ashakiran S, General & Family Physician
