This snake is highly venomous. Its venom causes pain, swelling, bruising and necrosis (death of body tissue), and it can also lead to abscesses. The venom disturbs blood clotting: the venom has thrombin-like proteases, which slow the clotting of fibrinogen, a protein needed to form clots. Bites can also cause high blood pressure and collapse.1

Between 1960 and 1975, about 500 cases were reported there each year, and 80% of them were attributed to one subspecies, B. n. diporus. In a study of 18 bite cases admitted to a hospital in São Paulo from 1975 to 1992, all patients had pain, 83% had swelling, 50% had bruising, 17% had necrosis and 12% developed coagulopathy (a clotting disorder).1

- Three antivenins made by the Instituto Butantan in Brazil can be used to treat bites from this species. Treatment with heparin might help the clotting problems caused by the venom.1
