Lactose-free milk is not a substitute chosen simply for milk allergy. Difficulty digesting lactose and allergy to milk protein are different. Use this guide to prepare information, not to diagnose yourself.
- Separate lactose and protein
- Read the ingredients
- Get emergency help for severe signs
- Prepare a consultation record

Separate digestion from allergy
The NHS describes lactose intolerance as difficulty digesting lactose. One stomach symptom cannot establish its cause. Removing lactose does not mean a dairy product is free of milk protein.
NHS: lactose intolerance · NHS: milk and dairy nutrition
When not to try another drink
Food allergy can be serious. Sudden throat or tongue swelling, trouble breathing or loss of consciousness needs local emergency help. Do not use a second drink of lactose-free milk as an allergy test.

Prepare a consultation note
Record food, amount, symptoms, timing and accompanying foods or medicines. Do not deliberately recreate a reaction. Discuss changes to a child’s milk or formula with their clinician.
A worked example
Stomach pain after milk does not itself establish milk allergy. Record the pattern and product for advice. Conversely, do not dismiss breathing problems as simple lactose intolerance.
Common questions
Does lactose-free mean milk-free?
No. Lactose and milk-protein avoidance are separate checks.
Can I choose any plant drink?
Check allergens and nutrition, and seek advice where needed.
