In brief: Suggestive symptoms
An allergy to formula (usually the milk or soy component) presents with characteristic symptoms.
Usually these include rash/hives or worsening eczema, swelling of lips/tongue/eyelid/face, cough/wheezing, vomiting/diarrhea. Not all patients experience all of these symptoms. Fussiness or colic is usually not secondary to a formula allergy. Skin or blood allergy tests can help diagnose an allergy.
