Vitamins on prescription: when the NHS still prescribes them

What NHS England's guidance says

NHS England publishes policy guidance on conditions for which over the counter items should not be routinely prescribed in primary care. The guidance covers 35 conditions: 8 self-limiting conditions and 27 minor conditions suitable for self-care. Probiotics and vitamins and minerals sit in a separate group, as items with limited evidence of clinical effectiveness. NHS England marks the vitamins and minerals section as updated in 2023.

The recommendation for vitamins and minerals is three words: do not prescribe. Maintenance or preventative treatment is not an exception. Being exempt from prescription charges does not on its own justify one either. Any prescribing outside the listed exceptions should be discontinued, according to the guidance.

When vitamins are still prescribed

The guidance lists these exceptions:

• a medically diagnosed deficiency, including for people with a lifelong or chronic condition, or who have had surgery causing malabsorption, with continuing need reviewed regularly
• calcium and vitamin D for osteoporosis
• prescription-only vitamin D analogues such as alfacalcidol
• malnutrition, including from alcoholism, with reference to NICE guidance
• people suitable for Healthy Start vitamins, which are commissioned separately and not supplied on prescription

For a medically confirmed deficiency, the guidance asks prescribers to choose the most cost-effective licensed product.

Pregnancy brings one more case. The NHS says a GP can prescribe a 5 mg dose of folic acid for people with listed risk factors, such as diabetes, a blood condition like sickle cell anaemia or thalassaemia, or a previous pregnancy affected by a neural tube defect. The standard 400 microgram tablet is bought from a pharmacy or supermarket.

The £9.90 charge against the shelf price

In England the prescription charge is £9.90 for each item. The table sets it against shelf prices read on 22 October 2026.

Tesco showed its folic acid as out of stock on the day. Chemist4U adds £3.95 delivery to orders under £39, which takes a single Valupak pack to £5.24. That is still £4.66 below the prescription charge.

If you are not exempt and the prescribed item is a vitamin also sold over the counter at the same strength, ask the pharmacist what it costs to buy. The NHS charge does not change with the shelf price.

Ways to pay less in England

Several groups pay nothing for prescriptions in England. Leaflet HC11 lists them, and the free prescriptions guide covers each one. The ones most relevant to prescribed vitamins are:

• pregnancy, or a baby born in the last 12 months, with a maternity exemption certificate
• a medical exemption certificate for a listed condition, such as diabetes mellitus treated by more than diet alone
• Universal Credit with no earnings or net earnings of £435 or less in the latest assessment period, or £935 with a child element or limited capability for work
• age under 16, 16 to 18 in qualifying full-time education, or 60 and over

If you pay for several items, a prescription prepayment certificate caps the cost. A 3-month certificate costs £32.05 and a 12-month certificate £114.50, which you can spread over 10 monthly Direct Debit payments.

Scotland, Wales and Northern Ireland

Prescriptions in Scotland are free, NHS inform says. In Wales, anyone registered with a Welsh GP gets free prescriptions from a pharmacy in Wales, and Welsh residents with an English GP can get an entitlement card for the same purpose. In Northern Ireland every prescription dispensed is free for everyone, with nothing to apply for. The charges by nation page sets out the differences.

Steps if you think you need a prescribed vitamin

1. Speak to your GP if you think you have a deficiency. Under the guidance, a diagnosed deficiency is the main exception.
2. If you are prescribed a vitamin in England, check the exemption list before paying the £9.90.
3. If you are pregnant, ask your midwife or doctor to apply for a maternity exemption certificate.
4. If you pay for more than a few items a year, compare the cost with a prepayment certificate.
5. Ask for form FP57 whenever you pay. If you later find you were exempt, the prescription refund process returns the charge, provided you claim within 3 months.

Mistakes that cost money

Asking for a prescription for a winter vitamin D supplement. The guidance rules out maintenance and preventative treatment, and Valupak tablets at Chemist4U cost 2.15p each.

Paying £9.90 while pregnant. A maternity exemption certificate makes every prescription free, including 5 mg folic acid.

Assuming an exemption certificate brings a prescription with it. The guidance says exemption from charges is not a reason to prescribe.

Paying for vitamin drops a child can get through Healthy Start. The scheme supplies them outside the prescription system.
