What Causes Itching In Genital Area After Starting Adderall?

My daughter is 7, and has been complaining about an itchy private area...she has never had a yeast infection before....but she did recently start taking adderall (after rchanging from concerta...which was causing bad stomach pain)...could the adderall be causing it or maybe the fact that she switched meds.she is miserable...and what can I give her...or do I take her to the pediatrician
