Excessive sweating in armpits is it caused by vyvyanse i take 40mg during the weekdays?

Sweating: Botox was used with success to improve sweating. See a plastic surgeon.

Excessive sweatings: Excessive sweating or hyperhidrosis is a common side effect of vyvanse (lisdexamfetamine), (lisdexamfetamine) although it shouldn't just localized to the armpit areas only. The only way to know is to stop vyvanse (lisdexamfetamine) and see if the sweating stop. If not, then u might just have idiopathic hyperhidrosis which is treated with antiperspirant, anticholinergic med, botox.... Don't stop any med without talking to your doctor first.
