I am concerned i drank too much during my accutane course as was unaware of the recommendation. however, my liver results always came back normal. should i be concerned? clearly, it is in past now so nothing i can do?

Alcohol consumption during Accutane use can cause liver damage. Since you tested normal for all your liver tests, you are safe. Some mild liver damage is reversible with time and good nutrition/water intake. This obviously must have happened for you as your liver appears unaffected.

Alcohol is a poison that never did anybody any good, ever, so stay away from it. It will destroy your brain cells, damage testicular cells that make testosterone, facilitate development of cancer in many organs, cause hepatitis, cirrhosis and pancreatitis etc. There is no safe level of alcohol intake. Quit while you are ahead.
