Drug reaction/event: A simple answer is that a drug event may be a listed side effect of the medication (such as fatigue, diarrhea, dizzyness) and may not be a reason to stop the medication. An adverse reaction is a reason to stop the medication and frequently involves an immune response or a response that is a danger to the patient.

What is the difference between an adverse drug reaction and side effect?

Same thing: It's the same thing - just two different terms. Some side effects could be beneficial and so not an "adverse" reaction but the terms refer to the same effect - unintended consequences (good or bad) of a therapy.
