Detoxification (including chelation)
Some children with autism may suffer from heavy metal toxicity, and may potentially benefit from therapies which support detoxification. Some may also benefit from chelation (removal of heavy metals). Oral DMSA (dimercaptosuccinic acid) is approved by the FDA for treating lead poisoning in children as young as one year of age. It has also been demonstrated to be able to bind and remove a wind range of toxic metals, including mercury, arsenic, tin, nickel and antimony. Oral DMSA has been used off-label for this purpose. I tis important to monitor kidney and liver function and complete blood counts when using DMSA, and although rare, serious side effects may occur.
