In brief: Very different
An allergic reaction refers to a process that normally does not occur with the administration of drug: specifically involved with histamine release and the signs and symptoms associated with histamine release such as: swelling, itching, low blood pressure, difficulty breathing, etc.
Adverse reactions are usually predictable but unwanted symptoms associated with a certain medication.
