Currently the only treatment for Cow Milk Allergy is total avoidance of cow milk proteins.

Initially, if the infant is breastfed, a strict elimination of the causal protein, i.e. the proteins from cow milk, from the diet of the lactating mother should be tested. If symptoms still persist or the infant is bottlefed, a cow milk substitute formula should be used to provide the infant with a complete source of nutrition, which does not provoke immune mediated symptoms.
If the cow milk allergy is diagnosed, the healthcare professional can prescribe a formula milk that is easy to use, palatable and enables optimal growth and development, that is also free from cow milk proteins.

Cow milk substitutes include soybean formulas (but many infants with milk allergies are also allergic to soy milk) and hypoallergenic formulas based on hydrolysed proteins and amino acid-based formulas.
In some countries, milk from other animals such as goats, sheep and mares have traditionally been used for patients with Cow Milk Allergy. But other species’ milk is not recommended for treatment of infants with Cow Milk Allergy: these milks are not nutritionally complete, are poor sources of certain vitamins (especially folic acid and vitamins B6, B12, C and D) and are only tolerated in a handful of infants with cow milk allergy.

Amino acid-based formulas (AAF) and extensively hydrolysed formulas (eHF) are the only products that are regarded as “hypoallergenic” and suitable for the treatment of Cow Milk Allergy.
