"i was administered dilauded in the er after having suffered a copperhead bite to the ankle. they administered the antivenin and morphine with phenergan (sp?) and returned after about 10 minutes to check my pain level-- no effect. the dilauded didn&#039;t completely stop the pain, but it definitely took the edge off. this was my first expirence taking any narcotic-- so both the morphine and dilauded caused the &quot;whoooosh&quot; sensation, stomach dropped, body felt very heavy... but that sensation was much greater with dilauded. shortly after getting the dilauded i started vomiting pretty heavily-- but no way to know if that was the venom, antivenom, morphine, or dilauded. lesson learned, don&#039;t step on a snake!"
