many view it as an endurance issue since it is a medication taken for the rest of your life
that is the first I have heard of it being actively harmful, but everyone's personal health, age and history will determine your doctors advice on how to take your medication.
Look at the phrasing of that clip off webMD. "Can be hard on liver" Can be... Like under certain circumstances such as already having liver damage or low function. Age and drinking history will play a role too
WebMD is like a blanket. It could have a high risk for one person and a very low risk for another.. you need the personalized touch of a doctor and your own medical history
