GUIDANCE ON THE DIAGNOSIS AND MANAGEMENT OF
COW’S MILK ALLERGY
This guideline is an interim update to the January 2015 guidelines following a formal review of
the specialised infant formula products available for prescription, and in light of changes to
local phlebotomy services.
The guideline is designed as a toolbox1 to primarily support GP’s and Childrens Health Teams in
the differential diagnosis and management of cow’s milk allergy, although it is relevant to all
health professionals involved with patients suffering with potential food allergy.
This guideline provides information about:
symptoms of food hypersensitivity
how to confirm a diagnosis of cow’s milk allergy
whether they require the use of specialised infant formula
when, how and what to prescribe
how to manage a child with cow’s milk allergy
if and when the child needs to be referred to secondary or specialist dietetic care.

Cow’s Milk Allergy (CMA)
Background
Food allergy is an adverse immune response to a food. It can be classified into IgE mediated
(type 1) and non-IgE mediated (type 4) reactions.
IgE mediated reactions are acute and frequently have rapid onset.
Non-IgE mediated reactions are generally characterised by delayed and non-acute
reactions.
Both types of reactions can occur in the same individual and IgE mediated allergy can develop
in individuals with previous non-IgE mediated symptoms, particularly following a prolonged
period of complete allergen exclusion.
Food allergy should not be confused with food intolerance, which is a non-immunological
reaction that can be caused by enzyme deficiencies, such as a lactase deficiency in Lactose
Intolerance (LI).
Lactose intolerance is rare in children under 3 years of age, unless onset of symptoms coincides
with an episode of gastro-enteritis. Typical symptoms of lactose intolerance include loose,
watery stools, abdominal bloating and pain, increased flatus and nappy rash. If other
symptoms are present such as rashes, eczema, vomiting, constipation or the child is not growing
well, they are more likely to have cow's milk allergy, even if some of the symptoms resolve
following lactose exclusion2. Refer to guidance on lactose intolerance.
CMA has been shown to affect between 1.8-7.5% of infants in the first year of life and it is
suggested that clinicians should anticipate that between 2-3 % of children have a CMA3. CMA
can develop in exclusively and partially breast-fed infants, as well as in bottle-fed infants and
when cow’s milk is introduced at weaning.

Symptoms of food allergy
Allergy to cow’s milk protein should be suspected in infants who present with any of the
symptoms listed in the following table (Table 1), in association with the introduction of cow’s
milk into their diet. The risk of atopy increases if a parent or sibling has atopic disease (20–40%
and 25–35%, respectively), and is higher still if both parents are atopic (40–60%)4.
NICE guidelines5 and subsequent NICE Food Allergy Quality Standards6 recommend that if food
allergy from any cause is suspected, then an allergy focused clinical history should be taken,
including family history of atopy and a physical examination conducted by a GP or other
competent medical personnel (see Appendix 1).
Diagnosis
Diagnosis of non-IgE mediated cow’s milk allergy
Diagnosis of non-IgE mediated CMA can be made if symptoms resolve after 2-6 weeks on a
cow’s milk elimination diet5-6. In children suffering from moderate to severe eczema, the
exclusion trial period is suggested to be between 6-8 weeks7. However, unless highly confident
of the response to the elimination diet (parents often describe them as being a different child)
or in infants who have had an extensive period of distressing symptoms prior to final resolution,
a firm diagnosis can only be made if re-occurrence of symptoms has been demonstrated
following a cow’s milk re-challenge5-6 (see Table 4). This re-challenge should not be done in
children who are thought to have acute IgE mediated allergy. In those with more severe,
distressing symptoms, resolution of symptoms can be accepted as diagnostic, with first re-
challenge occurring at 1 year of age, as outlined under treatment (p15-17).

Bottle-fed infants
If the mother is NOT breastfeeding exclusively, a hypoallergenic formula should be prescribed.
There are two types of hypoallergenic formula and the initial formula of choice will depend
upon the severity of presenting symptoms as outlined in Table 2.
Table 2 Hypoallergenic formulas to treat CMA in Nottinghamshire
Severity of CMA

For the majority of gastrointestinal and atopic symptoms of cow’s milk allergy
Extensively Hydrolysed Infant Formula (EHF):
1st line – casein based, lactose free
2nd line – whey based with lactose
1st Line: Nutramigen 1 with LGG or Nutramigen 2 with LGG (MJ Nutrition) (> 6 months age) (£10.87 for 400g tin)
2nd Line: SMA Althera (£10.68 for 450g tin)
Severe Faltering growth, severe infantile eczema, multiple food allergies, reactions to breast milk, iron deficiency anaemia due to GI blood loss, anaphylaxis, respiratory difficulties, other systemic reactions to trace amounts of allergen
Amino Acid Infant Formula (AAF)
1st line: Neocate LCP (£28.30 for 400g tin) or Neocate Junior (Nutricia) [> 12 months age) (£28.30 for 400g tin) (Flavours; unflavoured, vanilla)]
Second line EHF may be preferable for infants over 6 months due to palatability. If they still
have symptoms on Neocate LCP, they should be referred to a paediatrician. An alternative AAF
(SMA Alfamino or Nutramigen Puramino) could be tried while awaiting assessment, if cow’s
milk allergy is still suspected.
It is suggested in the first instance that approximately 1 weeks supply is prescribed i.e. 2 x 400g
tins or 1 x 800g tin, to ensure the product is tolerated.
Monthly prescriptions of hypoallergenic formula are expected to comprise of approximately
10-12 x 400-450g tins. This should reduce as solid intake increases.

Introduction of Hypoallergenic formula (HAF)
Due to the unpalatable taste of HAF, it is recommended in non-IgE mediated, delayed allergic
reactions to grade the children onto it. The rate that this is done will depend upon their age
(Table 3). This promotes acceptance and ensures tolerance of the product. Older children
(over 6 months) are more likely to accept the more palatable lactose containing EHF.

Once the 2-6 week exclusion trial is completed, the child’s symptoms should be reviewed. If
they continue to suffer from symptoms after 2 weeks on an extensively hydrolysed formula,
they should try an amino acid formula (AAF) (Table 2). If they still have symptoms on an AAF,
they should be referred to a paediatrician. An alternative AAF (SMA Alfamino or Nutramigen
Puramino) could be tried while awaiting assessment, if cow’s milk allergy is still suspected.
Otherwise they should return to normal formula.

For children taking solids
If the child is already taking solids, they will need to adopt a strict cow’s milk free diet. First line
information on cow’s milk exclusion is available for the family in Appendix 2. More detailed
dietary information can be obtained via the community dietitians if required.
Re-challenge to confirm diagnosis in bottle fed babies
If symptoms have improved on the exclusion trial, to confirm the diagnosis in non-IgE mediated
allergy, children should be re-challenged with normal formula, or yogurt if taking solids (Table
4).

Then introduce other dairy foods followed by gradually grading back onto normal infant formula (as per Table 3 in reverse)
If the child’s symptoms return on re-challenge, they should resume the hypoallergenic formula
(HAF) and/ or strict milk free diet as soon as this occurs, and a referral made to a community
dietitian for further practical advice on following the cow’s milk free diet, to ensure nutritional
adequacy is maintained and to advise on future re-challenging and long term prescription
requirements6. It may be appropriate for children who have had a complicated path to
diagnosis and ultimately require an amino acid formula, to delay the re-challenge process until
1 year of age, assuming symptoms have satisfactorily resolved.

Breast fed babies
In a small number of exclusively breastfed infants, CMA can develop, as cow’s milk proteins
from the mother’s diet can pass into breast milk. These infants tend to be some of the most
allergic and are more likely to suffer from multiple food allergies. For these infants, mothers
should be encouraged to continue to breast feed while following a strict cow’s milk protein free
diet. For infants with severe eczema, a cow’s milk and egg free diet is recommended.
Breast feeding mothers have calcium requirements of 1250mg/ day and 10mcg vitamin D daily.
If breast feeding mothers are entitled to Healthy Start vitamins (providing 10mcg vitamin D),
they only require a calcium supplement;
Calcichew x 2 daily, providing 1000mg calcium
Otherwise they will need a combined calcium and vitamin D supplement;
Calcichew D3 x 2 daily will provide 1000mg calcium and 10mcg vitamin D
Liaison with a dietitian is recommended as more detailed dietary information than that
available in Appendix 2 is likely to be required. If mothers are unable to follow a milk-free diet
despite support from their GP, health visitor and dietitian, then careful consideration should be
given as to whether breast-feeding should continue and, if not, the infant will require an Amino
Acid Formula (AAF). They should not be given Extensively Hydrolysed Formula (EHF) as the
cow’s milk protein content is similar to that found in breast milk.
An emergency back-up supply of formula (AAF if exclusively breastfed, or EHF if partially breast
fed where reaction only occurred with introduction of standard formula top ups) should be
considered, in case of sudden breastfeeding failure due to illness etc.
The formula recommended to treat CMA in breast-fed babies in Nottinghamshire is:
-1st line: Neocate LCP (Nutricia) (£28.30 for 400g tin), Neocate Junior (Nutricia) [> 12 months
age) (£28.30 for 400g tin) (Flavours; unflavoured, vanilla)]
Dr Lisa Waddell Produced February 2011 Ratified by NAPC January 2015 Updated May 2017 Review date: September 2018

If they still have symptoms on Neocate LCP, they should be referred to a paediatrician. An
alternative AAF (SMA Alfamino or Nutramigen Puramino) could be tried while awaiting
assessment, if cow’s milk allergy is still suspected.
Re-challenge to confirm diagnosis in breast fed babies
If symptoms have improved on the exclusion trial, to confirm the diagnosis in non-IgE mediated
allergy, breast fed children should be re-challenged by mum returning to a normal cow’s milk
containing diet. Referral should be made to a dietitian. If symptoms do not improve, the child
should be referred to a paediatrician.
Diagnosis of IgE mediated cow’s milk allergy
Children with suspected immediate IgE mediated reactions should be advised to adopt a strict
cow’s milk exclusion diet, which should be accompanied by resolution of symptoms (provide
the family with a copy of the BDA Milk Allergy fact sheet for interim first line advice on cow’s
milk avoidance, see Appendix 2). Unlike non-IgE mediated allergy, these children should not be
re-challenged with cow’s milk.
Key prescribing points:
Initial prescription of 1 weeks supply i.e. 2 x 400g/ 450g tins, to ensure the product is tolerated.
Monthly prescriptions of hypoallergenic formula are expected to comprise of: 10-12 x 400-450g tins
Once established on a HAF, prescriptions for the formula must be reviewed every 8-12 weeks for CMA to ensure continued improvement of symptoms.
A ‘review’ or ‘stop’ date should be stated at the time of the initial prescription.
Parents should be made aware from the beginning of how long the exclusion diet is likely to be needed.
Soya based formula should not be prescribed unless advised by a specialist. Breastfeeding is supported as the best form of nutrition for a good start in life for every child

Nottinghamshire County CCG’s
All children with suspected IgE mediated cow’s milk allergy should be referred to secondary
care, for assessment and allergy testing as necessary.
Nottingham City CCG
In children suspected of multiple IgE mediated allergies, those with suspected IgE mediated
allergy and asthma, and in those at risk of anaphylaxis and other systemic reactions, the child
should be referred to secondary care for diagnostic assessment and allergy testing5-6.
All other patients should be referred to the specialist community paediatric allergy dietitian
(extended role) for support with implementing a cow’s milk free diet and for interpretation of
the IgE allergy test (see Table 5).
Children with suspected IgE mediated allergy require allergy sensitisation tests to confirm the
diagnosis5-6,8. Specific IgE to cow’s milk alongside a total IgE can be organised by Nottingham
City GPs by providing the patient with a blood form and informing patient of/ booking patient
into a paediatric phlebotomy service as follows:

The following table provides an insight into interpretation of specific IgE allergy testing,
although it is expected that the community allergy dietitian or other health professional with
appropriate competencies will explain the results to the family following receipt of referral.
Table 5 Interpretation of specific IgE to cow’s milk results (ImmunocapTM)
Specific IgE (Grade)* Clinical implication for IgE cow’s milk allergy (CMA)
0 - 0.35 kU/L (Grade 0) Considered to be IgE negative if <0.1 kU/L9. Supports
diagnosis of IgE mediated CMA if >0.1kU/L. More likely to
be non-IgE mediated if <0.1. If unexpected result, refer to
secondary care for skin prick testing
0.35 – 0.7 (Grade 1) Supports diagnosis of IgE mediated CMA
0.7 – 3.5 (Grade 2) Supports diagnosis of IgE mediated CMA
3.5 – 17.5 (Grade 3) 2 yrs, 5kU/L has 95% positive predictive value for CMA4

17.5 – 50 (Grade 4)
50 – 100 (Grade 5)
>100 (Grade 6)
Very high levels can result from a high total IgE, but IgE
mediated CMA nevertheless highly likely
*Specific IgE results are only a measure of sensitisation and hence need to be interpreted in the
context of the allergy focused clinical history. They should not be used to predict the severity
of a clinical reaction, as systemic reactions can still occur at low, positive levels. Cow’s milk and
dairy products should therefore not be introduced to any child with a raised specific IgE to
cow’s milk (>0.1kU/L) without specialist support.

Referral
In accordance with NICE guidance5-6 relating to all forms of food allergy in children, referral to
secondary care should occur for on-going diagnostic assessment and management in infants
who have:
- had a systemic allergic reaction (acute or delayed)
- clinical/ parental suspicion of multiple IgE mediated reactions/ cross-reactions
- strong clinical suspicion of IgE mediated food allergy but allergy test results are negative
- IgE reactions to foods with a high risk of anaphylaxis e.g. tree nuts, peanuts, shellfish, kiwi,
sesame
- confirmed IgE mediated food allergy and concurrent asthma
- faltering growth or severe acute gastrointestinal reactions despite a cow’s milk exclusion
trial
If the infant does not have any of the above allergic manifestations associated with severe IgE
mediated or complex food allergy, then it is hoped that Nottingham City CCG GPs will feel
confident to diagnose and manage CMA with local expert community dietetic support, without
referral to secondary care. Referral to a paediatrician is indicated if the infant fails to respond
to dietary exclusion alone.
Referral to dietetic services across Nottinghamshire
Referral to registered paediatric dietitians in Nottinghamshire varies in light of differences in
commissioning and available local expertise in food allergy (Table 6). Referral to a dietitian
with appropriate competencies is essential if a diagnosis has been confirmed, to ensure
nutritional adequacy, provide practical support; especially during weaning and in presence of
food avoidance issues, review appropriateness of prescribed products, advise on re-challenging
and ensure against unnecessary long-term exclusion of foods6.

Treatment
Once the diagnosis has been confirmed i.e. they show improvement on a 2-6 week cow’s milk
elimination diet followed by deterioration on re-challenge (in non-IgE infants) or an
improvement with positive allergy sensitisation tests (in IgE infants), they should be given a
cow’s milk free diet for at least 6 months.
Babies should be weaned at the usual time onto a cow’s milk free diet and practical advice,
support and relevant literature will be provided by the dietitian on receipt of referral. Cow’s
milk and related products form a major food group which makes a significant contribution to
daily energy, protein, calcium, riboflavin and iodine intakes. Exclusion of this should therefore
not be taken lightly and it is essential that dietetic supervision is provided6.
Re-challenging at a later stage to determine tolerance
Children should be re-challenged after 6 months of cow’s milk (CM) exclusion, usually around
12 months of age to see if they have recovered. Whether the food challenge is done in hospital
or at home will depend upon the type and severity of the food allergy.
In infants diagnosed early in life (3-8 weeks of age) who have responded to Nutramigen with
LGG, it would be prudent to consider re-challenging around 6 months of age, to avoid potential
unnecessary elimination of dairy products from the weaning diet10. In IgE mediated infants, re-
challenging in the community would be considered on an annual basis and only following a
negative specific IgE to cow’s milk.
Cow’s milk challenge at home
If there is no anticipated risk of an acute reaction the challenge can be done at home i.e.
the allergy is thought to be a non-IgE mediated, delayed onset pattern of symptoms
or repeat specific IgE test is now negative
Dr Lisa Waddell Produced February 2011 Ratified by NAPC January 2015 Updated May 2017 Review date: September 2018
- 16 -
In infants with a strong personal/ family history of atopy however, particularly those with
moderate to severe eczema, an IgE sensitisation test to CM should be considered, to ensure
that their allergy has not evolved into IgE mediated allergy following an extended period of
complete CM avoidance3.
It is best to plan the challenge when the child is well and stable. Cow’s milk should gradually be
introduced, starting with small amounts in baked products as more severe reactions may occur
after a period of exclusion3. A cow’s milk re-challenge diet sheet is available from the dietitians
which should be adapted for each individual based on previous symptoms and whether they
have failed previous challenges. The child should already be under the care of a dietitian who
advises on this. If the re-challenge fails, it is essential that any child not under the dietitian is
subsequently referred to ensure nutritional adequacy, review appropriateness of prescribed
products, provide practical support, and advise on future re-challenging.
If the re-challenge around 12 months age is unsuccessful, then it should be repeated at 6
monthly intervals. Ingestion of small amounts of cow’s milk protein in baked foods if tolerated
should be encouraged, as it is thought to encourage development of future tolerance. It is not
however, appropriate to continue to include cow’s milk in the diet if it is causing untoward
reactions, and frequent re-challenging every few weeks to months can have a negative impact
upon the child’s well-being.
Cow’s milk challenge in hospital
If there has been an immediate-type respiratory reaction or anticipated risk of a severe
reaction, cow’s milk will need to be re-challenged in hospital. As it is not possible to predict the
severity of future reactions however, all children with a history of mild or moderate immediate-
type reactions indicative of IgE mediated allergy should also be re-challenged in hospital, unless
previously positive specific IgE blood tests are now negative.
Dr Lisa Waddell Produced February 2011 Ratified by NAPC January 2015 Updated May 2017 Review date: September 2018
- 17 -
If the IgE sensitisation test is positive at 1 year of age, annual specific IgE tests to cow’s milk
should be undertaken, and CM re-challenge only done at home if the result is negative
(ImmunocapTM value of <0.1 kU/L). If by 3 years of age, specific IgE to CM is still positive, it
would be appropriate to refer them to secondary care for review, and a re-challenge in hospital
may be considered to determine whether the child is still symptomatic. The chance of reacting
clinically however, is still likely if the specific IgE to CM is > 15kU/L or > 5kU/L in infants < 2 yrs
(95% positive predictive value)8. A significant reduction in results over time appears to be
indicative of developing tolerance.
Ongoing management of children with CMA
Children with mild to moderate IgE mediated symptoms (those who have had only or mainly
cutaneous reactions on previous exposure) will need their IgE sensitisation status monitored on
an annual basis, and re-challenge only undertaken in the community if the tests are negative,
otherwise a supervised re-challenge with access to full resuscitation facilities will be required.
Ongoing prescription of specialised formula
All infants requiring hypoallergenic formula will continue to require monthly repeat
prescriptions until at least 1 year of age.
At 1 year of age, if soya is tolerated, a soya-based junior milk is available from supermarkets:
Alpro 1+ soya milk (1 litre cartons, known as giraffe milk due to picture on front). There are
currently no other milk substitutes available designed for children of 1-2 years of age.
Therefore, if there is any doubt about the nutritional adequacy of the child’s diet,
hypoallergenic formula should continue to be prescribed until 2 years of age.
Most children with non-IgE mediated allergy will have outgrown their allergy by 3-5 years of
age11, although IgE mediated CMA can persist into adolescence12. The child should be given

further challenges with CM if still allergic at 5 years of age; annually until adulthood is reached
to ensure that the diet is not unnecessarily restrictive.
There needs to be a co-ordinated approach amongst GP’s, health professionals in both primary
and secondary care and parents/ carers including:
Monitoring of growth and nutrition on a 6-12 monthly basis
Identification and management of emerging comorbidities – GPs to conduct an annual
review of all children with CMA, including a physical examination and review of
medications relating to atopy/ allergies e.g. Epipens, asthma, eczema and rhinitis
medications, prescription of infant formulas and micronutrient supplements
Attempts to minimise the impact of having CMA on the quality of life
Dietetic supervision until at least 2 years of age, depending upon individual needs

Soya-based Formula
In 2004, the Chief Medical Officer issued a statement advising against the use of soya-based
formula in infants with cow’s milk protein allergy or lactose intolerance due to its phyto-
oestrogen content, which could pose a risk to the long-term reproductive health of infants13.
There is also an increased risk of sensitisation to soya protein. Whilst only a small number of
children with IgE mediated CMA become sensitised to soya (10-14%), 30-64% of children with
non-IgE mediated CMA conditions such as enteropathy or enterocolitis can develop an allergy
to soya14.
Soya based formula should therefore not be prescribed unless advised by a competent health
professional. Parents wishing to feed their infant soya-based formula should be advised of the
risks and instructed to buy the formula over the counter rather than have it prescribed. Use of
soya formula should be limited to exceptional circumstances to ensure adequate nutrition, for
example, infants of vegan parents who are not breastfeeding. Where health professionals
consider it to be the most suitable alternative for the management of cow’s milk allergy or
galactosaemia in infants over 6 months of age, it should be prescribed as an alternative to
hypoallergenic formula.
Key Prescribing Points
Soya formula should not be used in infants with food allergy during the first 6 months of life15.
Soya formula should not be used in infants suffering from moderate to severe gut symptoms, which could be associated with cow’s milk induced enteropathy or enterocolitis.14
A ‘review’ or ‘stop’ date should be stated at the time of the initial prescription
Parents should be made aware from the beginning of how long the exclusion diet is likely to be needed

Appendix 2 - Checking food labels
European Union (EU) food labeling laws require that labels must clearly state whether cow’s milk,
in addition to other allergens such as soya, egg and wheat, is an ingredient in a food product.
These laws will also have to apply to unpackaged foods and when eating out in the EU from
December 2014. If you travel outside the EU, be aware that labelling laws are different and check
ingredients carefully. Foods sold loose eg. from a bakery, delicatessen or butcher; foods packed
for direct sale eg. sandwich bars, in-store bakeries, and some catering products will have to
provide allergen information, whether it’s on a chalk board, chart or provided verbally. You could
carry a ‘chef card’ to give to restaurant staff stating which allergens you need to avoid. These can
be downloaded from http://multimedia.food.gov.uk/multimedia/pdfs/chefcard.pdf
More information on food allergy labeling is available from the FSA:
http://multimedia.food.gov.uk/multimedia/pdfs/publication/allergy-leaflet.pdf
There are many ways in which cow’s milk can be labeled, so carefully check the ingredients list on
food items and avoid foods which contain:
Cow’s milk (fresh, UHT) Butter milk, butter oil Casein (curds), caseinates
Evaporated milk Condensed milk Calcium caseinate
Yogurt, fromage frais Cheese Sodium caseinate
Margarine Butter, Ghee Hydrolysed casein
Ice cream Cream/ artificial cream Hydrolysed whey protein
Milk powder Skimmed milk powder Whey, whey solids
Milk protein Milk solids Whey protein
Modified milk Lactoglobulin Lactoalbumin
Lactose - in most cases only needs to be avoided if your child has lactose intolerance or is thought
to have secondary lactose intolerance as part of a pattern of GI-related non-IgE mediated
symptoms

By law you must be able to clearly identify that a product contains milk/ a milk derivative. For
example, if casein is listed, it should tell you in brackets afterwards that this is ‘from milk’.
Allergens will be highlighted in the ingredients list in bold, italics, underlined or highlighted. Only
if the product does not have an ingredients list will a statement be allowed.
Example of food label containing cow’s milk
Olive spread (margarine):
Ingredients: Vegetable oils [including olive oil (22%)], water, whey powder (milk), salt (1.3%),
stabiliser (sodium alginate), emulsifier (mono and diglycerides of fatty acids), lactic acid, natural
flavouring, vitamins A and D, colour (carotenes)
Allergy Advice: for allergens, see ingredients in bold.
This margarine is therefore not suitable for a cows’ milk free diet.
'May contain…'/’Made in a factory…’ labeling: Some labels say ‘may contain cow’s milk’ or ‘not
suitable for cow’s milk allergy’ as the manufacturer may not be able to ensure that the product
does not accidentally contain small amounts. Discuss with your dietitian whether you need to
avoid these foods.
Allergy Alerts: Sometimes foods have to be withdrawn or recalled if there is a risk to consumers
because the allergy labeling is missing or incorrect or if there is any other food allergy risk. These
alerts are available from the Food Standards Agency website. It is also possible to subscribe to a
free email or SMS text message alert system to receive automatic messages whenever such
Allergy Alerts are issued. To subscribe go to: www.food.gov.uk/safereating/allergyintol/alerts.
