I take vyvanse, (lisdexamfetamine) and have ocd. have a serious skin picking problem. meth can cause that symptom. can amphetamines cause skin picking too?

Possibly: Amphetamines increase central nervous system arousal. Some individuals may experience agitation and heightened anxiety and associated symptoms. If you are observing that this behavior increases with use of amphetamine or with current prescribed medications please discuss with your prescribing provider.

Yes: Amphetamines such as Vyvanse (lisdexamfetamine) can increase anxiety and picking type of behavior. Speak to your prescriber about an alternative medication such as Provigil or Nuvigil

Yes.: Talk with your doctor to find out if it is doing this.

OCD & skin picking: It is likely that both compulsive skin picking vis a vis side effects from some stimulants might pose a challenge to adjust treatment. It appears that it would necessary to consult with a professional who is an expert in psychopharmacology. There is really no easy answer without a thorough evaluation.

Yes, and so can: Vyvanse, (lisdexamfetamine) which has a version of amphetamine in it. OCD doesn't help matters, as this can also manifest in heightened attention to body conditions. I'd check with your prescribing MD first, possibly to reduce or change your prescriptions. Then see a psychologist and/or a dermatologist. I assume you have ADHD. Are you treating this?
