All patients with pica should be screened for iron deficiency and lead poisoning. Pica is a risk factor for lead poisoning. For patients with mildly elevated blood lead levels (i.e., < 45 μg/dL), addressing risk factors for lead poisoning (e.g., by treating pica) and limiting lead exposure by removing the source (e.g., paint, furniture, water, toys, soil, dust, secondhand exposure) suffices. Chelation therapy (e.g., with oral succimer) is only recommended in children with a blood lead level > 45 μg/dL.
