Enfamil O-Lac with LIPIL

The first-choice formula for lactose intolerance

Enfamil O-Lac is a lactose-free formula designed for babies with mild gastrointestinal discomfort (colic, bloating, wind, diarrhoea) due to lactose intolerance.1

  • Made with cow’s milk, Enfamil O-Lac has the same taste and appearance as routine formula, which means it is readily accepted by babies.
  • It is nutritionally complete and suitable for babies from birth.

Gastroenteritis: a common cause of temporary lactose intolerance

  • Temporary lactose intolerance is common after gastroenteritis2
  • May last up to 4–6 weeks when associated with moderate to severe dehydration3
  • Infants most at risk of lactose intolerance include those:
    • Under 1 year or underweight4
    • With severe diarrhoea, especially when caused by rotavirus enteritis3

Enfamil O-Lac is clinically proven to speed recovery

  • Shortens the duration of diarrhoea in dehydrated, hospitalised children5
  • Produces significant weight gain vs routine formula in infants with recent gastroenteritis following rehydration5

Excellent nutritional profile

  • Nutritionally complete for infants up to 6 months of age, and can be used as part of a lactose-free diet in older children
  • Contains cow’s milk and has a similar taste to routine formula, so well accepted
  • Enriched with LIPIL to support brain and eye development6–8 Learn more

What is the difference between lactose intolerance and cow’s milk allergy?

CMA is often confused with lactose intolerance, but they are actually two distinct conditions.1,9CMA is an immune reaction to proteins in cow’s milk, whereas lactose intolerance is a non-immune condition, in which people cannot digest the milk sugar, lactose.1,9Nonetheless, a small proportion of CMA patients with gastrointestinal symptoms may also have concomitant lactose intolerance.

Both conditions may lead to digestive problems such as diarrhoea, bloating and flatulence, but rashes, eczema, and breathing difficulties are only seen in CMA.9

Is Enfamil O-Lac suitable for infants with cow’s milk allergy?

Like CMA, lactose intolerance is managed by avoiding milk and dairy products. Lactose-free formula, such as Enfamil O-Lac, and lactose-free dairy products are widely available; however these are not suitable for children with CMA as they contain whole cow’s milk protein and so are not hypoallergenic. Expert guidelines recommend extensively hydrolysed formulas, such as Nutramigen LIPIL for CMA.1,

Can parents buy Enfamil O-Lac without a prescription?

Enfamil O-Lac is available from most local pharmacies and can be ordered using PIP code 241-4605.
