Succimer has been linked to a low rate of transient serum aminotransferase elevations during therapy, but its use has not been linked to cases of clinically apparent liver injury with jaundice.</p></div><div id="Succimer.Background"><h3>Background</h3><p>Succimer (sux&#x02019; i mer) or dimercaptosuccinic acid (DMSA) is an orally available heavy metal chelating agent that is used to treat lead poisoning in children. Succimer is an organo-sulfur compound with two sulfhydryl groups that bind divalent metal ions such as lead, cadmium, mercury, and arsenic. Succimer does not significantly chelate essential metals such as zinc, copper or iron, and its specificity, safety and oral availability make it preferable to other chelating agents for treating lead poisoning such as Ca-EDTA which must be given intravenously and dimercaprol (British anti-Lewisite [BAL]) which requires intramuscular administration. Succimer has been shown to lower blood lead levels and improve symptoms of chronic lead poisoning. Succimer was approved for use in the United States in 1991, and current indications are for treatment of lead poisoning in pediatric patients with plasma lead levels above 45 &#x000b5;g/dL. It is used off label to treat adults with lead poisoning and for therapy of arsenic and mercury intoxication. Succimer is also used in naturopathic medicine administered orally as well as intravenously as a part of chelation therapy for various conditions. Succimer is available in capsules of 100 mg generically and under the brand name Chemet. The recommended dose is 10 mg/kg (or 350 mg/m<sup>2</sup>) every 8 hours for 5 days, and reduce to every 12 hours for an additional 2 weeks of therapy, with a minimum 2 week rest period between repeated courses if lead levels remain high. Side effects are generally mild and may include headache, nausea, anorexia, diarrhea, rash, neutropenia and renal dysfunction. Uncommon, but potentially severe adverse events include hypersensitivity reactions. Intravenous administration of succimer as used in naturopathic medicine has not been approved for any indication and has been associated with sudden death attributed to hypocalcemia.</p></div><div id="Succimer.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>In clinical trials conducted in children with lead poisoning, serum aminotransferase levels elevations occurred in 7% of succimer- vs 4% of placebo-treated subjects. However, <a class="def" href="/books/n/livertox/glossary/def-item/glossary.alanine-aminotransferase-alt-/">ALT</a> levels above 5 times the upper limit of normal were rare (&#x0003c;1% of treated patients) and no child had to stop therapy early because of liver test abnormalities. There have been no clinical reports of liver injury with jaundice attributed to succimer, but it has had limited general clinical use.</p><p><a class="def" href="/books/n/livertox/glossary/def-item/glossary.likelihood-score/">Likelihood score</a>: E (unlikely cause of clinically apparent liver injury).</p></div><div id="Succimer.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The mechanism of injury accounting for serum enzyme elevations during succimer therapy is not known. Succimer-metal chelates are eliminated in the urine.</p></div><div id="Succimer.Outcome_and_Management"><h3>Outcome and Management</h3><p>Serum aminotransferase elevations above 5 times the upper limit of normal (if confirmed) should lead to dose reduction or temporary cessation. Succimer has not been implicated in cases of acute liver failure, chronic hepatitis or vanishing bile duct syndrome. Despite the lack of evidence of significant liver injury from succimer, the product label recommends routine liver testing before and every week during therapy. There does not appear to be cross reactivity in risk for hepatic injury between succimer and other chelating agents including deferoxamine or deferiprone.</p><p>Drug Class: <a href="/books/n/livertox/ChelatingAgents/">Chelating Agents</a>, Lead Chelators</p></div></div><div id="Succimer.PRODUCT_INFORMATION"><h2 id="_Succimer_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><p>
