Description: Administration of secretin, a hormone involved in digestion. This hormone (which can be natural or synthetic) is administered intravenously, orally or transdermally.

Research Summary: Fourteen large, well-designed studies with many hundreds of individuals with autism spectrum disorders have shown that secretin is ineffective (Williams, Wray, & Wheeler, 2005). Secretin is an inappropriate treatment for individuals with autism spectrum disorders.

Recommendations: Secretin is not a useful intervention for individuals with autism spectrum disorders.
