The treatment and prevention of vitamin D deficiency.

As an adjunct to specific therapy for osteoporosis in patients with vitamin D deficiency.

Fultium-D₃ 20,000 IU Capsules are indicated for use in adults, the elderly and adolescents.

Posology

Paediatric population

- Prevention of vitamin D deficiency 12-18 years: 20,000 IU (1 capsule) every 6 weeks

- Treatment of vitamin D deficiency 12-18 years: 20 000 IU (1 capsule) once every 2 weeks for 6 weeks

Adults:

- Prevention of vitamin D deficiency: 20,000 IU/month (1 capsule), higher doses may be required in certain situations, see below

- Treatment of vitamin D deficiency: 40,000 IU/week (2 capsules) for 7 weeks, followed by maintenance therapy (equivalent to 1,400-2,000 IU/day, such as 2-3 capsules per month, may be required. Follow-up 25(OH)D measurements should be made approximately three to four months after initiating maintenance therapy to confirm that the target level has been achieved)

Certain populations are at high risk of vitamin D deficiency, and may require higher doses and monitoring of serum 25(OH)D:

- Institutionalised or hospitalised individuals

- Dark skinned individuals

- Individuals with limited effective sun exposure due to protective clothing or consistent use of sun screens

- Obese individuals

- Patients being evaluated for osteoporosis

- Use of certain concomitant medications (e.g., anticonvulsant medications, glucocorticoids)

- Patients with malabsorption, including inflammatory bowel disease and coeliac disease

- Those recently treated for vitamin D deficiency, and requiring maintenance therapy.

Fultium-D₃ 20,000 IU Capsules should not be given to children under 12 years due to the risk of choking.

Infants and young children (0-12 years)

Not recommended for children under 12 years.

Pregnancy and breastfeeding

Fultium-D₃ 20,000 IU capsules are not recommended during pregnancy unless the clinical condition of the woman requires treatment.

Colecalciferol and its metabolites are excreted in breast milk. Overdose in infants induced by nursing mothers has not been observed but allowance for any maternal dose should be made when prescribing vitamin D products to a breast-fed child.

Method of administration

This medicine is taken orally.

The capsule should be swallowed whole with water, preferably with the main meal of the day.

Hypersensitivity to vitamin D or any of the excipients in the product

Hypervitaminosis D

Nephrolithiasis

Diseases or conditions resulting in hypercalcaemia and/or hypercalciuria

Severe renal impairment

Vitamin D should be used with caution in patients with impairment of renal function and the effect on calcium and phosphate levels should be monitored. The risk of soft tissue calcification should be taken into account. In patients with severe renal insufficiency, vitamin D in the form of colecalciferol is not metabolised normally and other forms of vitamin D should be used (see section 4.3, contraindications).

Caution is required in patients receiving treatment for cardiovascular disease (see Section 4.5 – cardiac glycosides including digitalis).

Fultium-D3 20,000 IU Capsules should be prescribed with caution to patients suffering from sarcoidosis because of the risk of increased metabolism of vitamin D to its active form. These patients should be monitored with regard to the calcium content in serum and urine.

During long-term treatment with an equivalent daily dose exceeding 1,000 IU vitamin D the serum calcium values must be monitored. Renal function should also be checked by measuring serum creatinine. It is recommended to reduce the dose or interrupt treatment if the calcium content in the urine exceeds 7.5 mmol / 24 hours (300 mg / 24 hours).

Allowances should be made for vitamin D supplements from other sources.

The need for additional calcium supplementation should be considered for individual patients. Calcium supplements should be given under close medical supervision.

Medical supervision is required whilst on treatment to prevent hypercalcaemia.

Fultium-D₃ 20,000 IU Capsules should not be given to children under 12 years.

Concomitant treatment with phenytoin or barbiturates can decrease the effect of vitamin D because of metabolic activation. Concomitant use of glucocorticoids can decrease the effect of vitamin D.

The effects of digitalis and other cardiac glycosides may be accentuated with the oral administration of calcium combined with Vitamin D. Strict medical supervision is needed and, if necessary monitoring of ECG and calcium.

Simultaneous treatment with ion exchange resins such as cholestyramine or laxatives such as paraffin oil may reduce the gastrointestinal absorption of vitamin D.

The cytotoxic agent actinomycin and imidazole antifungal agents interfere with vitamin D activity by inhibiting the conversion of 25-hydroxyvitamin D to 1,25-dihydroxyvitamin D by the kidney enzyme, 25-hydroxyvitamin D-1-hydroxylase.

Studies have shown safe use of doses up to 4000 IU during pregnancy although studies in animals have shown reproductive toxicity (see section 5.3). The recommended daily intake for pregnant women in the United Kingdom is 400 IU, however, in women who are considered to be vitamin D deficient a higher dose may be required. During pregnancy women should follow the advice of their medical practitioner as their requirements may vary depending on the severity of their disease and their response to treatment

Vitamin D and its metabolites are excreted in breast milk. Overdose in infants induced by nursing mothers has not been observed; however, when prescribing additional vitamin D to a breast-fed child the practitioner should consider the dose of any additional vitamin D given to the mother.

Fultium-D₃ 20,000 IU Capsules have no influence on the ability to drive and use machines.

Adverse reactions are listed below, by system organ class and frequency. Frequencies are defined as: uncommon (>1/1,000, <1/100) or rare (>1/10,000, <1/1,000).

Metabolism and nutrition disorders

Uncommon: Hypercalcaemia and hypercalciuria.

Skin and subcutaneous disorders

Rare: Pruritus, rash and urticaria.

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.

The most serious consequence of acute or chronic overdose is hypercalcaemia due to vitamin D toxicity. Symptoms may include nausea, vomiting, polyuria, anorexia, weakness, apathy, thirst and constipation. Chronic overdoses can lead to vascular and organ calcification as a result of hypercalcaemia. Treatment should consist of stopping all intake of vitamin D and rehydration.

Pharmacotherapeutic group: Vitamin D and analogues

ATC code: A11CC05

In its biologically active form vitamin D3 stimulates intestinal calcium absorption, incorporation of calcium into the osteoid, and release of calcium from bone tissue. In the small intestine it promotes rapid and delayed calcium uptake. The passive and active transport of phosphate is also stimulated. In the kidney, it inhibits the excretion of calcium and phosphate by promoting tubular resorption. The production of parathyroid hormone (PTH) in the parathyroids is inhibited directly by the biologically active form of vitamin D3. PTH secretion is inhibited additionally by the increased calcium uptake in the small intestine under the influence of biologically active vitamin D3.

Vitamin D is well absorbed from the gastro-intestinal tract in the presence of bile. It is hydroxylated in the liver to form 25-hydroxycolecalciferol and then undergoes further hydroxylation in the kidney to form the active metabolite 1, 25 dihydroxycolecalciferol (calcitriol). The metabolites circulate in the blood bound to a specific α - globin, Vitamin D and its metabolites are excreted mainly in the bile and faeces.

Vitamin D is well known and is a widely used material and has been used in clinical practice for many years. As such toxicity is only likely to occur in chronic overdose conditions where hypercalcaemia could result.

Colecalciferol has been shown to be teratogenic in high doses in animals (4-15 times the human dose). Offspring from pregnant rabbits treated with high doses of vitamin D had lesions anatomically similar to those of supravalvular aortic stenosis and offspring not showing such changes show vasculotoxicity similar to that of adults following acute vitamin D toxicity.
