Succimer, sold under the brand name Chemet among others, is a medication used to treat lead, mercury, and arsenic poisoning.[4] When radiolabeled with technetium-99m, it is used in many types of diagnostic testing.[5] A full course of Succimer lasts for 19 days of oral administration.[4] A second course should be given when more than two weeks pass after the first course.[4]

Common side effects include vomiting, diarrhea, rash, and low blood neutrophil levels.[4] Liver problems and allergic reactions may also occur with use.[4] Whether use during pregnancy is safe for the baby is unclear.[6] Dimercaptosuccinic acid is in the chelating agent family of medications.[4] It works by binding with lead and a number of other heavy metals, allowing them to leave the body in the urine.[4]

Succimer has been used medically since the 1950s.[7][8] It is on the World Health Organization's List of Essential Medicines.[9] In the United States, no generic version was available as of 2015.[10]
