Objective: To estimate the cost-effectiveness of using an extensively hydrolyzed casein formula containing the probiotic Lactobacillus rhamnosus GG (eHCF + LGG; Nutramigen LGG) as a first-line management for cow’s milk allergy compared with eHCF alone, and amino acid formulae in Spain, from the perspective of the Spanish National Health Service (SNS). Methods: Decision modeling was used to estimate the probability of immunoglobulin E (IgE)-mediated and non–IgE-mediated allergic infants developing tolerance to cow’s milk by 18 months. The models also estimated the SNS cost (at 2012/2013 prices) of managing infants over 18 months after starting a formula as well as the relative cost-effectiveness of each of the formulae. Results: The probability of developing tolerance to cow’s milk by 18 months was higher among infants with either IgE-mediated or non–IgE-mediated allergy who were fed eHCF + LGG compared with those fed one of the other formulae. The total health care cost of initially feeding infants with eHCF + LGG was less than that of feeding infants with one of the other formulae. Hence, eHCF + LGG affords the greatest value for money to the SNS for managing both IgE-mediated and non–IgE-mediated cow’s milk allergy. Conclusion: Using eHCF + LGG instead of eHCF alone or amino acid formulae for first-line management of newly-diagnosed infants with cow’s milk allergy affords a cost-effective use of publicly funded resources because it improves outcome for less cost. A randomized controlled study showing faster tolerance development in children receiving a probiotic-containing formula is required before this conclusion can be confirmed.
