A serum that contains antitoxin specific for an animal or insect venom. Antivenin is prepared from the sera of immunized animals.

Patient care

Antivenins are foreign proteins that often induce allergic reactions in patients who receive them. The likelihood of allergic reactions is reduced by prior administration of epinephrine.

black widow spider antivenin

Antitoxic serum obtained from horses immunized against the venom of the black widow spider (Latrodectus mactans) and used specifically to treat bites of the black widow spider. The serum is available from Merck Co., Inc., West Point, PA 19486.
