Aknenormin is a brand name for 'isotretinoin'. Accutane is also a form of isotretinoin.
I believe I have read people getting EC and other skin problems after taking Accutane as well. So the problem here appears to be isotretinoin.
I recommend researching as much as you can about isotretinoin, since it seems to have caused you this problem. I'm going to read up on how exactly this drug works to figure out if there's a way to heal from the particular damage it causes.
