How long should an infant consume extensively hydrolyzed formula before switching to regular formula?
Generally, infants can switch from extensively hydrolyzed formula to standard infant formula after 6 to 9 months. Details are as follows:
Extensively hydrolyzed formula is a hypoallergenic formula. Through special processing techniques, the milk proteins in the formula are broken down into small peptides. This type of formula, which contains amino acid-based structures, is a specialized medical-grade product. Clinically, infants with severe allergies need to consume extensively hydrolyzed formula for a certain period. As the child grows, their digestive system, immune function, and skin barrier gradually mature—typically within 6 to 9 months—and allergy symptoms tend to subside. At this point, they can gradually transition to a standard infant formula. Extensively hydrolyzed formula provides good nutrition, meeting the growth and developmental needs of infants, and is suitable for those allergic to regular formula.
It should be noted that extensively hydrolyzed formula is not intended for long-term use. Unlike regular infant formula, it serves a therapeutic purpose, so its duration and method of use must be guided by a physician.
