Meg replied: "When you go to the doctor, always let him/her know about any prescription medication you are taking. Accutane is a pretty hard core drug that can affect your liver and cholesterol levels, brain swelling, the whole deal. It's important to make sure your doc knows so that s/he can choose the right medication for you.
More likely than not, you should be able to take Amoxicillin with Accutane, but I would let your doc make that judgment call...
Good luck! :]"
