Copperhead venom has an estimated lethal dose around 100 mg, and tests on mice show its potency is among the lowest of all pit vipers, and slightly weaker than that of its close relative, the cottonmouth.

Engelmann and Obst (1981) list value of 0.12 mg/kg SC, with an average venom yield of 120 mg per bite and a maximum record of 400 mg.

Based ...

Any bite from a venomous snake should be considered serious and medical treatment sought.
There are dry copperhead bites — meaning venom does not get injected into the bite victim — and envenomations, which may require antivenom in an emergency department.
