Is it possible to predict an idiosyncratic reaction?

To be clear, an idiosyncratic reaction is abnormal in nature and is therefore not possible to predict who may develop one, when, or what specific form it will take ahead of time. While the good news is that idiosyncratic reactions aren’t all that common, the bad news is that when they do occur, many tend to be life-threatening in nature.

Why is the liver a common site of idiosyncratic reactions?

Most commonly, this results in the death of liver cells, causing jaundice, failure, or even death. The reason the liver is a common site of idiosyncratic reactions is because it is the place where drugs are converted into an active form, prior to entering your general circulation.
