Delicol in drops Food for special medical purposes for babies; for dietary management of colic caused by transient lactose intolerance. Delicol contains the enzyme lactase, which breaks down milk sugar, i.e. lactose, into simple sugars - glucose and galactose. In newborns and young infants, the digestive system may be immature and not secreting sufficient amounts of natural lactase. The presence of undigested lactose in the large intestine can cause gas, stomach pain and colic. Administering the lactase enzyme with each serving of milk allows for a more thorough digestion of lactose and reduces the risk of infant colic.
