The Arizona bark scorpion is the most [[Venom (poison)|venomous]] scorpion in North America, and its venom can cause severe pain (coupled with numbness, tingling, and vomiting) in adult humans, typically lasting between 24 and 72 hours.<ref name=":0" /> Temporary dysfunction in the area stung is common; e.g. a hand or possibly arm can be immobilized or experience convulsions. It also may cause loss of breath for a short time. Due to the extreme pain induced, many victims describe sensations of electrical jolts after [[envenomation]]. Two recorded fatalities have occurred in the state of [[Arizona]] since 1968; the number of victims stung each year in Arizona and [[New Mexico]] is estimated to be in the thousands.<ref name=UA>{{cite web | url = http://ag.arizona.edu/pubs/insects/az1223/ | title = Scorpions | work = Cooperative Extension, College of Agriculture & Life Sciences | publisher = The University of Arizona | access-date = June 20, 2008 }}</ref> 

=== Antivenom===
An [[antivenom]] was developed for this species at [[Arizona State University]] by Dr. Herbert L. Stahnke, and produced in quantities sufficient to treat individuals within the state of [[Arizona]]. This antivenom was not FDA approved, but use within the state of Arizona was allowable and very successful in shortening the duration of symptoms and hospitalization. Production of this antivenom ceased by 2000 and the product was unavailable by 2004. A Mexican-produced antivenom, Anascorp [Antivenin Centruroides (scorpion) F(ab′)<sub><sup>2</sup></sub>, Laboratorios Silanes, Instituto Bioclon SA de CV], received FDA approval on August 3, 2011, and is now in use.<ref name=FDA-Anascorp>{{cite web | year = 2011 | url = https://www.fda.gov/BiologicsBloodVaccines/BloodBloodProducts/ApprovedProducts/LicensedProductsBLAs/FractionatedPlasmaProducts/ucm266726.htm | archive-url = https://web.archive.org/web/20110805200500/http://www.fda.gov/BiologicsBloodVaccines/BloodBloodProducts/ApprovedProducts/LicensedProductsBLAs/FractionatedPlasmaProducts/ucm266726.htm | url-status = dead | archive-date = August 5, 2011 | title = August 4, 2011 Approval Letter - Anascorp | access-date = December 9, 2012 }}</ref>
