As of 2002, there is no standard treatment for pica. Currently, the most effective strategies are based on behavior modification, but even these treatments have achieved limited success.

  1. Identified nutritional deficiencies and other problems, such as lead toxicity, should be addressed medically.
  2. Treatment emphasizes psychosocial, environmental, and family guidance approaches.
  3. Other successful treatments have been mild aversion therapy followed by positive reinforcement.
  4. Medications may be helpful in reducing the abnormal eating behavior, if pica occurs in the course of a developmental disorder, such as mental retardation, or pervasive developmental disorder.
