Thimerosal, also known as thiomersal, is an organomercury antiseptic and antifungal agent used as a preservative in vaccines, immunoglobulins, nasal sprays, and contact lens solutions. Thimerosal was used as a component of topical antiseptic solution and antiseptic ointment for treating cuts and as a component of nasal sprays, eye solutions, vaginal spermicides, and diaper rash treatments, but reevaluation of the drug in the 1980s demonstrated ineffectiveness and toxicity in topical pharmaceutical products, and topical thimerosal was withdrawn from the market. Thimerosal is used as a preservative for influenza (flu) vaccines in multidose vials for adults. Thimerosal is also used during the manufacturing process for two childhood vaccines to prevent the growth of microbes, and it is removed later in the process. It had been removed from uses in vaccines and products that target immunoglobulins. In the United States of America (USA) and European Union countries, thiomersal is no longer used in childhood vaccines due to public fears, although the Food and Drug Administration (FDA) review of 1999 found no evidence of harm from the use of thimerosal as a vaccine preservative other than local hypersensitivity reactions.
