Venomous scorpions that typically induce severe clinical signs include the Arabian or Asian Fat-Tailed Scorpion (Androctonus crassicauda), Hottentotta genus scorpions, and Hemiscorpius lepturus. The sting causes minimal local inflammation, but the systemic effects can be serious and include nystagmus, paresthesia, referred pain, myoclonus, hypersalivation, tachycardia, hypertension, fever, and increased respiratory secretions.
