Fig. 1-Latrodectus species-Widow Spiders
Calcium gluconate infusion, advocated in the past, has proved only minimally useful and is no longer recommended.

Fig. 2 - Loxosceles reclusa spider (Brown Recluse Spiders)
Recently the use of dapsone has gained popularity for prevention of lesion progression in potentially necrotic wounds seen within 48 to 72 hours of a bite. Dapsone is a leukocyte inhibitor that in theory can minimize the local inflammatory component of cutaneous loxoscelism, thereby preventing or lessening subsequent skin necrosis.
