Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Most patients bitten by copperhead snakes do not currently receive antivenom. Some snakebite victims have long term problems with the function of the limb that was bitten. This study will determine whether early administration of antivenom to patients with mild to moderate copperhead snakebites reduces long-term complications.
