We report the case of a 22-year-old female who was bitten on the shoulder by a spider subsequently identified as a female Cupboard spider (Steatoda grossa). She developed nausea, vomiting, and severe local and regional pain, similar to that seen in latrodectism. Symptoms were treated successfully with red-back spider antivenom (RBSAV). ⋯ Venom effects could also be reversed by the addition of antivenom after application of venom to the preparation. Although severe envenomation is uncommon following the bite of Steatoda spp. it may resemble latrodectism. These results indicate that RBSAV is likely to be effective in reversing symptoms of envenomation and should be considered in the treatment of patients with distressing or persisting symptoms.
