My mom has better health insurance than me. Both our dermatologists warned us. Maybe it also has to do with the school/state of a dermatologist. I do not think you should ask a dermatologist, though. It would be best to call pharmacists at the local pharmacy. They will speak to you for free, and educate you about common side effects. If I choose to listen to a dermatologist, I am going with the one who warns me of possible side effects. Case closed.
