This information is adapted from general advice from a panel of US snakebite experts convened in May 2010. No algorithm can anticipate all clinical situations. Other valid approaches exist, and deviations from this information based on individual patient needs, local resources, local treatment guidelines, and patient preferences are expected. This algorithm is not intended to represent a standard of care. For more information, please see the accompanying manuscript, available at

the reasoning behind the Unified Treatment Algorithm.


Did you know?

It has been estimated that 7000-8000 people are bitten by venomous
snakes per year. The number of morbidities can be decreased with preparation for aggressive and immediate medical intervention.1
