The composition of Entitis is as follows: Bulking agent: Isomalt; Streptococcus salivarius K12 (milk); Anti-caking agent: Magnesium salts of fatty acids; Aroma; Cholecalciferol (vitamin D). It shows that the bacterial strain found in the preparation is obtained from cow's milk. In this situation, I would advise against using the product, as the child's allergic reaction to the preparation may be strong.

It would be worth considering other probiotic options that do not contain milk and lactose:
