Methemoglobinemia from isobutyl nitrite preparations.
Ingestion of preparations containing isobutyl nitrite can lead to rapidly fatal methemoglobinemia. We report the cases of three patients presenting with methemoglobinemia secondary to ingestion or inhaling the contents of an over-the-counter room odorizer preparation containing isobutyl nitrite. The condition was treated successfully with administration of intravenous methylene blue.
