⚕For healthcare professionals — Summary of Product Characteristics (SmPC)Full SmPC: dosage, interactions, contraindications, warnings+
4.1. Therapeutic indications
For the treatment of Vitamin C deficiency including the treatment and prevention of scurvy.
4.2. Posology and method of administration
Posology
Adults and children over 4 years:
Treatment: Not less than 250 mg daily in divided doses.
Maximum daily doses:
Adults and children over 12 years, 1000 mg.
Children 4 – 11 years, 500 mg.
The elderly:
As for adults. As the dietary intake of vitamin C may be less in the elderly, they are at greater risk of being deficient in this vitamin.
Method of administration
For oral administration.
4.3. Contraindications
Hypersensitivity to ascorbic acid or to any of the excipients listed in section 6.1.
Ascorbic acid should not be given to patients with hyperoxaluria.
4.4. Special warnings and precautions for use
Increased intake of ascorbic acid over a prolonged period may result in an increased renal clearance of ascorbic acid, and deficiency may result if the intake is reduced or withdrawn rapidly (see section 4.8).
Ascorbic acid may interfere with tests and assays for urinary glucose, giving false negative results with methods utilising glucose oxidase with indicator (e.g. Labstix, Tes-tape) and false positive results with neocuproin methods.
Estimation of uric acid by phosphotungstate or by uricase with copper reduction and measurement of creatinine in non-deproteinised serum may also be affected.
High doses of ascorbic acid may give false negative readings in faecal occult blood tests.
Patients with rare hereditary problems of galactose intolerance, total lactase deficiency, glucose-galactose malabsorption should not take this medicine as it contains lactose.
4.5. Interaction with other medicinal products and other forms of interaction
Ascorbic acid may reduce the absorption of amphetamines.
Ascorbic acid may increase the oral absorption of iron.
Concurrent administration of ascorbic acid with desferrioxamine enhances urinary iron excretion. Ascorbic Acid may increase the risk of cardiovascular adverse effects when given with desferrioxamine. Ascorbic acid should be used with caution in patients receiving desferrioxamine and cardiac function should be monitored.
Concomitant administration of aspirin and ascorbic acid may interfere with absorption of ascorbic acid. Renal excretion of salicylate is not affected and does not lead to reduced anti-inflammatory effects of aspirin.
Concomitant administration of aluminium-containing antacids may increase urinary aluminium elimination. Concurrent administration of antacids and ascorbic acid is not recommended, especially in patients with renal insufficiency.
Co-administration with amygdalin (a complementary medicine) can cause cyanide toxicity.
Ascorbic acid may interfere with biochemical determinations of creatinine, uric acid and glucose in samples of blood and urine.
4.6. Fertility, pregnancy and lactation
Pregnancy
For ascorbic acid no clinical data on exposed pregnancies are available.
Animal studies do not indicate direct or harmful effects with respect to pregnancy, embryonal/foetal development, parturition or postnatal development. Pregnant women should exercise caution.
Breast-feeding
Ascorbic acid is excreted in breast milk. Though again caution should be exercised, no evidence exists suggesting such excretion is hazardous to the infant.
Fertility
No data available.
4.7. Effects on ability to drive and use machines
Ascorbic acid has no known effect on the ability to drive and use machines.
4.8. Undesirable effects
Large doses of ascorbic acid may cause diarrhoea.
Renal and urinary disorders:
Patients known to be at risk of hyperoxaluria should not ingest ascorbic acid in doses exceeding 1 gram daily, as there may be increased urinary oxalate excretion. However such a risk has not been demonstrated in normal, non-hyperoxaluric individuals. Ascorbic acid has been implicated in precipitating haemolytic anaemia in certain individuals with a deficiency of glucose-6-phosphate dehydrogenase.
Increased intake of ascorbic acid over a prolonged period may result in an increase in renal clearance of ascorbic acid, and deficiency may result if the intake is reduced or withdrawn rapidly. Doses of more than 600mg have a diuretic effect.
Reporting of suspected adverse reactions:
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
4.9. Overdose
Symptoms
At doses of over 3 grams per day unabsorbed ascorbic acid is chiefly excreted unmetabolised in the faeces. Absorbed ascorbic acid additional to the body's needs is rapidly eliminated. Large doses of ascorbic acid may cause diarrhoea and the formation of renal oxalate calculi. Symptomatic treatment may be required.
Ascorbic acid may cause acidosis or haemolytic anaemia in certain individuals with a deficiency of glucose 6-phosphate dehydrogenase. Renal failure can occur with massive ascorbic acid overdosage.
Management
General supportive measures should be employed as required.
