Management of Corn Allergy in Patients Taking Dicyclomine

Understanding the Risk

Pharmaceutical excipients commonly derived from corn include starch and pregelatinized starch, which must have their source verified to ensure safety for patients with corn allergy, as recommended by the American Gastroenterological Association 1, 2

The American Gastroenterological Association recommends contacting the pharmacist to identify all inactive ingredients in the specific dicyclomine formulation being prescribed and to request documentation of the source of any starch-containing excipients 1, 2, 3
The physician should avoid generic substitutions, as sources can change frequently between manufacturers, and add the statement "As ordered if corn-free or provide a corn-free equivalent" to the prescription, as suggested by the American Gastroenterological Association and Praxis Medical Insights 1, 2, 3

High-risk patients, such as those with a history of anaphylaxis to corn or poorly controlled asthma, should avoid medications with uncertain corn content, according to the American Academy of Allergy, Asthma, and Immunology 4, 5, 6

The physician bears responsibility for ensuring medication safety in patients with known food allergies, as emphasized by the American Gastroenterological Association and Praxis Medical Insights 1, 2, 3
The American Academy of Allergy, Asthma, and Immunology recommends having emergency treatment available, such as an epinephrine auto-injector, if administering any medication with uncertain corn content to a corn-allergic patient 4, 5, 6, 7
