Treatment for lead poisoning begins with removing the sources of lead and providing balanced nutrition. These measures are usually sufficient to limit exposure to lead and reduce lead levels in the body.

Old paint chips and dirt are the most common sources of lead in the home. Lead-based paint and the dust and dirt that come from its decomposition should be removed by professionals. In the workplace, removal of sources usually involves removing lead dust that is in the air, as well as making sure adults don't bring contaminated dust or dirt into the home on clothes worn for work.

Balanced nutrition includes adequate amounts of vitamins and minerals such as iron, calcium, and vitamin C. A person who eats a balanced, nutritious diet absorbs less lead than a person whose diet is inadequate.

If removing the source of lead and balancing nutrition do not reduce lead levels, or if the blood lead level is very high, chelation therapy may be used. Chelation therapy is a process that rapidly reduces the amount of lead stored in the body. Drugs called chelating agents cause metals like lead to bind to them, and then they are eliminated from the body through urine. Because chelating agents increase the absorption of lead and other metals, it is essential that sources of lead exposure be removed before a person is treated.

Prevention, primarily through screening of both children and adults, is the most effective means of reducing or eliminating the effects of lead poisoning. Damage from lead poisoning, especially to the central nervous system, is often incurable and may not improve with treatment.
