Oral cromolyn sodium in milk induced anaphylaxis.

The medical literature contains numerous references to the use of oral cromolyn sodium in gastrointestinal disturbances (abdominal pain, diarrhea, ulcerative colitis) and dermatologic illnesses (urticaria, infantile eczema, purpura). But there are few, if any, reports of anaphylactic reactions to foods which have been successfully controlled using oral cromolyn sodium. This paper reports the results of treatment with oral cromolyn in a 7-year-old child who had acute, severe anaphylaxis after ingestion of milk or foods containing milk. After 3 months of oral cromolyn therapy, the patient was able to tolerate small amounts of milk and moderate amounts of foods containing milk.
