Hi,
Thanks for posting in HCM.
I understand your concern.
Vyvanse contains 'Lisdexamfetamine', which is used to treat attention deficit
hyperactivity disorder (ADHD).
Common side effects which are encountered with the use of this medication include: Nausea, vomiting,
constipation,
abdominal pain, loss of appetite, dry mouth, headache,
nervousness, dizziness, disturbed sleep, sweating, weight loss, irritability and
restlessness.
Since sweating is one of the listed side effects, what you could be experiencing might be due to the intake of drug. If any of these effects persist or worsen, you need to consult your doctor promptly to evaluate the cause, so that it can be specifically addressed.
Hope the information provided would be helpful.
All the best.
