Aptamil Pepti 1

Suitable from birth, Aptamil Pepti 1 is formulated for the dietary management of cows’ milk allergy (CMA).

How it works

Aptamil Pepti 1 is similar in composition to our standard infant milks, apart from the protein which has been broken down (extensively hydrolysed) to make it less likely to cause an allergic reaction. It also includes lactose for improved taste, to help your baby enjoy each feed and support weight gain.

What is cows’ milk allergy?

CMA is the most common food allergy in infants. Although most children eventually grow out of their milk allergy, its diagnosis and management can be a worrying time for parents. The good news is, with prompt diagnosis by a healthcare professional, treatment and expert dietary advice, CMA can be effectively managed and its impact reduced to a minimum. If you think your child has a cows' milk allergy, you should always get in contact with your healthcare professional for a correct diagnosis.
