Local Vitamin supplementation in alcohol misuse guideline


1. Non-specific B-group deficiencies should be treated with Vitamin B Compound Strong tablets, which contains thiamine riboflavin, nicotinamide and pyridoxine

2. Pyridoxine - Rare cases of peripheral neuropathy have been reported after prolonged treatment at high doses. The risk of harm can be avoided by reducing daily intake to 10mg. Where patients are on higher doses to treat deficiency or to counter Isoniazid-induced neuropathy, the risk is outweighed by the benefit.


9.6.3 Vitamin C

Ascorbic acid tablets


1. Because of poor diet the elderly can be prone to the development of subclinical scurvy; prophylactic doses of Vitamin C are recommended for patients at risk. Vitamin C may be useful for prevention and treatment of pressure sores and the treatment of burns.

2. Large doses have the potential to interfere with a number of biochemical tests, but this is unlikely with the exception of faecal occult blood. Doses of 1g/day may produce a false negative result for faecal occult blood.

3. Ascorbic acid 1g effervescent tablets are not prescribable on prescription by GPs.
