Acute intermittent porphyria
Can I die from an attack of acute intermittent porphyria?
While it is possible that an acute attack can be deadly, it is very rare for a person with acute intermittent porphyria to die from an attack. This is because we have good treatments for the most dangerous symptoms. However, death may occur if a person develops liver cancer or if they need a liver transplant and it is not successful.
