Prescribing Guidance for Vitamins and Minerals in Primary Care

In line with NHS England’s guidance on conditions for which over-the-counter items should not be routinely
prescribed Bradford District and Craven CCG does not support the routine prescribing of vitamins and minerals on
prescription unless indicated for actual vitamin or mineral deficiency. Vitamins and minerals should not be prescribed
as a ‘general pick-me-up’ or as a dietary supplement.
Exceptions:
      Medically diagnosed deficiency, including for those patients who may have a lifelong or chronic condition or
         have undergone surgery that results in malabsorption. Continuing need should be reviewed on a regular
         basis (NB maintenance or preventative treatment is not an exception).
      Calcium and vitamin D for osteoporosis.
      Malnutrition including alcoholism.

Vitamins and minerals are essential nutrients which most people should be able to get from eating a healthy, varied
and balanced diet. The Eatwell Guide https://www.nhs.uk/live-well/eat-well/the-eatwell-guide/ is a useful tool which
can be used to demonstrate to people how a healthy, varied and balanced diet can be achieved.

       Many vitamin and mineral supplements are classified as foods, not medicines, and therefore do not have to
        go through the strict criteria laid down by the Medicines and Healthcare products Regulatory Agency (MHRA)
        to confirm their quality, safety and efficacy before reaching the market. It is therefore not deemed
        appropriate for such preparations to be routinely funded on the NHS.
       There is insufficient high quality evidence to demonstrate clinical effectiveness of vitamins and minerals.
       Taking too many vitamins and minerals, or for too long could be harmful.

Recommendations for prescribers:
    Discontinue prescribing vitamins and minerals on FP10 for patients where treatment is not in line with
     recommendations.
    If patients still want to take vitamins and minerals for dietary supplementation or as a ‘pick-me-up’, they
     should be advised that these can be purchased as self-care over-the-counter with the support of the
     community pharmacist. For information on daily amounts and dietary sources sign post patients to
     https://www.nhs.uk/conditions/vitamins-and-minerals/

       NHS Healthy Start vitamins are recommended for pregnant and breast-feeding women and children under 5,
        as a preventative measure. These vitamins are not on prescription. In Bradford, Airedale and Wharfedale all
        infants up to 6 months age receive free Healthy Start vitamin drops, after 6 months age infants and children
        can receive the vitamins through either of the following ways:

            1. Free vitamins via the Health Start scheme if eligible. Information can be found on the Healthy Start
               website
            2. Purchased at designated local health centres/community pharmacies
            3. Health Visitors can issue free vitamins up to 2yrs age for children at high risk of deficiency.

In the Craven area, all Healthy Start vitamin drops need to be purchased or accessed via the Healthy Start scheme.

All pregnant women receive free NHS healthy Start vitamin tablets: Breast feeding women can purchase the vitamins
at designated local health centres/community pharmacies or via the Healthy Start scheme if eligible.

Bariatric surgery

Patients will be required to stay on lifelong nutritional supplements to counter the malabsorption effects of
bariatric surgery and have lifelong monitoring of their nutritional status.

It is recommended that patients purchase their multivitamin and mineral supplements OTC as agreed
before surgery. Existing patients may continue to receive their vitamin and mineral supplements on
prescription in exceptional circumstances.

Bradford Teaching Hospitals NHS Foundation Trust Bariatric Dietitians will provide patients with a list of
suitable preparations to self-purchase and advise on the appropriate dose to take depending on the type of
surgery the patient has undergone.
