I just did a search on here and it certainly seems like stimulants cause acne for some people.

I have been on ritalin a few months, just switched to adderall and this acne is driving me crazy! I used to get the odd pimple but my skin was always clear. Since I started the ritalin my forehead and cheeks and neck have been breaking out and my pores are definitely more clogged.

I have not changed my cleaning routine so it is obvious to me that ritalin was the cause.

For those of you who started breaking out after taking meds, what have you done? Any improvement?

I am 30 and not in the mood to deal with acne!

I've noticed that my forehead is prone to breaking out when I took Xanax (at night to sleep) and Adderall for more than week. I've never had pimples when young, or acne, so it was unusual to see these tiny little colorless bumps on my forehead.
I lowered the dose of the Xanax and skip nights without it and now my skin has cleared again.
I don't know if Ritalin and Xanax have anything in common, to cause that when mixed with Adderall. (I also take Prozac, but the combo of that and Adderall hasn't caused breakouts before I started taking Xanax)
Maybe adding more anti-oxidants to your diet may help clearing your skin of the toxins that the meds may be causing.
Have lots of berries and green tea as well as supplements, and see if it helps.

I was really hoping my recent bout of acne was a result of having just had a baby *in june (hormones finally getting back to normal... grasping straws)* and an overly hormonal period....

I didn't even have it this bad when I was in high school some umpteen years ago.

I will say, I've started taking Dexedrine now about a week or so ago and the acne is nearly gone. BUT, i'm also no longer on my period.

If it doesn't come back in the next week or so, I'm blaming the Adderall and praising the dexedrine for "curing" me. lol
