it would be more useful to ask a pharmacist about drug/drug reactions, they know a LOT about meds..its kind of their job.
I too am having cystic break outs, my dr didn't want to refer me to dermatology yet, we did just have a weather change...I am post menopausal but it doesn't matter, my mom is in her 70s and can still get acne on occasion. neither of us take hormone replacement as she is a breast cancer survivor and that makes me at risk as well.
