Guidelines for the use of infant formulas to treat cows milk protein allergy: an Australian consensus panel opinion.

Three types of infant formula (soy, extensively hydrolysed and amino acid) may be appropriate for treating cows milk protein allergy. Selection of a formula depends on the allergy syndrome to be treated. Extensively hydrolysed formula is recommended as first choice for infants under 6 months of age for treating immediate cows milk allergy (non-anaphylactic), food protein-induced enterocolitis syndrome, atopic eczema, gastrointestinal symptoms and food protein-induced proctocolitis. Soy formula is recommended as first choice for infants over 6 months of age with immediate food reactions, and for those with gastrointestinal symptoms or atopic dermatitis in the absence of failure to thrive. Amino acid formula is recommended as first choice in anaphylaxis and eosinophilic oesophagitis. If treatment with the initial formula is not successful, use of an alternative formula is recommended.
