What is the recommended initial dietary change for suspected cow's milk protein allergy?

• A. Continue cow's milk formula with antihistamines
• B. Switch to a lactose-free cow's milk based formula
• C. Switch to a protein hydrolysate or free amino acid formula
• D. Switch to a soy-based formula

Answer: (C)

When suspected cow's milk protein allergy, the aim is to avoid the offending protein. For infants who are formula-fed, the best initial dietary change is to switch to a formula in which cow's milk proteins are extensively broken down or absent—either a protein hydrolysate formula or an amino acid–based formula. These options provide nutrition with much lower allergenicity, helping to reduce or prevent the allergic reaction while still meeting nutrition needs. Antihistamines don’t remove exposure to cow's milk protein and aren’t a dietary management strategy. A lactose-free formula still contains cow's milk protein, so it doesn’t address the allergy. Soy-based formulas may still pose allergenic risk in CMPA and are not preferred as the first-line change for suspected CMPA.
