An anaphylactic reaction is the correct term for a severe allergic reaction involving multiple body systems. In anaphylaxis, the body's immune system overreacts to an allergen, leading to symptoms such as difficulty breathing, low blood pressure, hives, and swelling. This reaction can be life-threatening and requires immediate medical attention, often with the administration of epinephrine.

The other options are not correct in this context:

- Adverse effect typically refers to a harmful or undesired effect of a medication.

- Side effect is an unintended or secondary effect of a medication that is not the primary intended action.

- Overdose refers to taking an excessive amount of a substance, which can lead to toxicity or severe reactions but is not specific to allergic reactions involving multiple body systems.
