About CMA

  • CMA is an adverse immune reaction to cow’s milk protein presenting with immediate and/or delayed symptoms2,9
  • CMA is the most common childhood food allergy affecting 2-7.5% of infants9
  • Quality of life is profoundly reduced for patients with CMA and their families10
  • For formula-fed infants, management comprises avoidance of cow’s milk and use of suitable hypoallergenic formulas.2

Guideline recommendations

  • Expert guidelines recommend AAFs for formula-fed infants with severe CMA, multiple food allergies, or when an eHF is ineffective as initial treatment for mild-to-moderate CMA1,2
  • A critical expert review suggests that AAF is also warranted in the following conditions:11
    • failure on an eHF
    • eosinophilic oesophagitis
    • faltering growth (particularly with GI tract/skin involvement and multiple food eliminations)
    • anaphylaxis.

Evidence for use

  • Nutramigen* PURAMINO* has proven efficacy in infants with severe CMA and multiple food allergies;3 it is:
    • 100% amino acid formula
    • effective management of CMA symptoms3[C]
    • proven to support normal growth3[A]
    • well accepted: 100% of infants had no allergic reactions or adverse events3[C]
    • lactose free
    • contains DHA to support normal visual development6-8[B]
    • certified halal and kosher.
  • MCT oil (33%[D]) provides an easily available source of fats and energy in case of fat malabsorption:4,5
    • increased MCT supply is important in patients with disturbances in digestion and absorption (e.g. SBS)12
    • the balance of MCTs and LCTs is expected to provide fast energy absorption, while also stimulating gut adaptation.12,13


  • Not recommended for premature babies unless directed and supervised by an HCP.
