Prevention of AIN is not always possible. It helps to avoid contact with the offending medicine in the case of allergic reaction. Other prevention depends on the underlying cause of infection, such as avoiding exposure to strep.
Most cases of kidney damage can be reversed with treatment. But a few cases of AIN may lead to lasting kidney failure.
AIN is not catching and cannot be spread to others. Certain underlying conditions, such as mononucleosis, may be catching.
