Yes, I am a 45 year old female who works out at the gym and I wear nylon stretch pants. I recently started taking adderall and developed a yeast infection in the last two days. Is it possible that the adderall may be causing the infection. Admittingly, I deal with some stress, but have been working out frequently for about a month now and again, only recently developed the yeast infection. The adderall, I've only been taking for one week. Can you help?
