Apocynum spp.

Common name(S) Dogbane, hemp dogbane, Indian hemp, prairie dogbane, spreading dogbane.

Toxin(s) Cardiac glycosides.

Toxic part(s) Entire plant.

Signs Most of today's literature is based on a report that may have confused the dogbanes with Nerium oleander, because both genera belong to the Apocynaceae family. Signs in animals are said to be cold extremities, hyperthermia, hypothermia, mydriasis, sore mouth, anorexia, gastric distress, tachycardia (or bradycardia), and death.

Treatment Treatment is symptomatic and supportive (see Section One). Digoxin immune Fab (ovine) (Digibind, Glaxo Wellcome, Inc., Research Triangle Park, N.C.) has been reported to be of value in treating animals poisoned by ingesting oleander. Human poison control centers do not recommend it for cases of dogbane ingestion.
