Allergic reactions to a scorpion sting

How an allergy differs from the venom itself

Last reviewed 2026-07-20 Sources 3 Read 4 min
The short version

As with bee and wasp stings, some people can have an allergic reaction to a scorpion sting.1 An allergy is a different thing from the venom’s ordinary effects, and the whole-body allergy signs (spreading hives, swelling of the face or throat, trouble breathing) mean call 911.

Two different things: venom and allergy

The venom’s normal effects are local pain, swelling, and tingling caused directly by the toxin. An allergic reaction is your immune system overreacting, and it can happen to some people just as it does with bee or wasp stings.1 University of Arizona clinicians stress the distinction: do not automatically treat a sting as an allergic reaction, because the medicines for allergy are not the right response to ordinary venom symptoms.3

For the striped bark scorpion specifically, the University of Arkansas notes that claims of severe allergic reactions attributed to this species have not been well substantiated, so a severe allergy is possible but not something documented as common.2

Allergy warning signs

▲ Signs of a serious allergic reaction, call 911
  • Hives or swelling spreading well beyond the sting
  • Swelling of the face, lips, tongue, or throat
  • Difficulty breathing, wheezing, or tightness in the throat
  • Dizziness, fainting, or a feeling that something is very wrong

A normal sting causes symptoms at the sting site. A reaction spreading across the body is the difference that matters.1

These are the general signs of anaphylaxis to any sting. We did not find a scorpion-specific, human allergy grading in an authoritative source, so treat the above as standard sting-allergy guidance and, when in doubt, call Poison Control at 1-800-222-1222.
