Rattlesnakes are the most common poisonous snakes in the U.S.--especially in the West. The danger or potency of a bite depends on the amount of venom injected by the snake and the type of toxin—which can vary depending on the snake. It also makes a difference where the bite is located. A bite on the leg is usually not as dangerous as a bite on the face. Swelling from a bite on the nose may cause suffocation if it shuts off the air passages.
