This compound is a confirmed animal carcinogen. It can emit toxic fumes of NOx and mercury vapor when heated.[2] In 1998, use of nitromersol (and other mercury-containing products) as OTC first-aid antiseptics and products for diaper rash and vaginal contraceptives was disallowed by the FDA.[3] Nitromersol can cause hypersensitivity reactions, but it is still in use as a preservative for vaccines and antitoxins.[4]
