Patients discharged from Secondary care on Oral Nutritional Supplements (ONS):

  • Do not routinely add ONS to repeat prescription without review
  • Check the indication for the prescription and the duration required
  • Check current nutritional status (e.g. appetite, weight, height if available, weight loss, factors affecting dietary intake)
  • Consider issuing 1 months prescription as ‘acute’
  • Agree a review appointment (at review check weight, BMI and ‘MUST’ score) before issuing a further prescription


Initiating Oral Nutritional Supplements (ONS) in Primary Care: 

Oral Nutritional Supplement Prescribing for Malnourished Adults

Food First advice (click here) should be trialled for 2 - 4 weeks. If goals are not achieved, consider prescribing ONS twice daily, supported by a planned review process.

The other criteria that should be fulfilled before an ONS is prescribed, as discussed in the NICE guideline CG32, are essentially that:

  • Patient’s MUST score is appropriate
  • Patient’s condition is ACBS approved

ONS are only available on FP10 prescriptions for specific indications as agreed by the Advisory Committee on Borderline Substances (ACBS).


Standard ACBS Indications: Disease-related malnutrition, intractable malabsorption, pre-operative preparation of patients who are undernourished, dysphagia, proven inflammatory bowel disease, following total gastrectomy, short bowel syndrome, bowel fistula.


 Please ensure clear review/stopping criteria are established at the time of prescribing.

Please note, the thickening of standard oral nutritional supplements is not recommended and patients with dysphagia requiring oral nutritional supplements should only have texture level specific supplements or pre-thickened supplements prescribed on the advice of a dietitian or SALT team. 

9.5.3 Phenylketonuria

Patients with phenylketonuria (PKU) are managed with a low protein diet, including special low protein versions of common foods such as flour, bread and pasta which are not freely available other than on prescription.

ACBS indications for prescribing low protein foods include inherited metabolic disorders, renal or liver failure requiring a low protein diet. Thus prescribing low protein foods for individuals with PKU is in line with ACBS criteria. Once initiated by the specialist centre, it is the responsibility of the GP to continue prescribing these low protein foods.

Please see guidance on prescribing in PKU below:

9.5.4 Special diets

Coeliac disease

Intolerance to gluten in coeliac disease is managed by completely eliminating gluten from the diet.

Following consultations by North Somerset and South Gloucestershire CCGs (Summer 2017) and Bristol CCG (early 2018) the newly formed Bristol, North Somerset and South Gloucestershire Clinical Commissioning Group (BNSSG CCG) no longer prescribes gluten free foods to patients aged 18 and over. Prescriptions are still available for those patients aged under 18 from a limited choice of products. 

If you have further questions or feel you need further support in managing your condition, please contact the surgery to make an appointment.

Bristol, North Somerset and South Gloucestershire (BNSSG) CCG have developed guidance for prescribing within the area:
