Patient leaflet - Vitamin D3 400 IU capsules, soft

1. WHAT VITAMIN D3 CAPSULES ARE AND WHAT THEY ARE USED FOR

The active substance of Vitamin D3 Capsules is vitamin D3. Vitamin D helps the body to absorb calcium and enhances bone formation.

This medicine is recommended in the following cases:

  • To prevent vitamin D deficiency in pregnant and breastfeeding women when there is a risk of deficiency.

Vitamin D3 Capsules are used in adults and adolescents.

2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE VITAMIN D3 CAPSULES

Do not take Vitamin D3 Capsules:

  • if you are allergic to vitamin D or any of the other ingredients of this medicine (listed in section 6)
  • if you have high levels of calcium in your blood (hypercalcaemia) or urine (hypercalciuria)
  • if you have severe kidney problems (severe renal impairment)
  • if you have high levels of vitamin D in your blood (hypervitaminosis D)
  • if you have kidney stones or calcium deposits in your kidneys.

Warnings and precautions

Talk to your doctor or pharmacist before taking Vitamin D3 Capsules if:

  • You have high tendency to kidney stone formation.
  • You have cancer or any other condition that may have affected your bones.
  • You have parathyroid hormone imbalance

    (pseudohypoparathyroidism).

If you have any of the following conditions, your doctor will monitor the levels of calcium or phosphate in your blood, or the level of calcium in your urine:

  • if you are on long term treatment with this medicine
  • if you have kidney problems
  • if you suffer from ‘sarcoidosis’; an immune system disorder which may affect your liver, lungs, skin or lymph nodes.

Children

Vitamin D3 Capsules are not indicated for use in children under 12 years.

Other medicines and Vitamin D3 Capsules

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

This is especially important if you are taking:

  • diuretics (water tablets). As your doctor will need to monitor your blood calcium levels regularly
  • corticosteroids (‘steroids’ e.g. prednisolone, dexamethasone). As your dose of vitamin D may need to be increased
  • colestyramine (a cholesterol lowering medicine) or laxatives (e.g. paraffin oil). As they reduce vitamin D absorption
  • heart medicines (cardiac glycosides). As you should be monitored by a physician and possibly an ECG and your calcium levels monitored
  • anticonvulsants (for the treatment of epilepsy), sleeping medicines (e.g. hydantoin barbiturates) or primidone. As these reduce the effect of vitamin D
  • calcitonin, etidronate, gallium nitrate, pamidronate or plicamycin. As these decrease blood calcium levels
  • calcium containing products in high doses. As these increase the risk of high blood calcium levels
  • magnesium containing products (e.g. antacids). As these should not be used during treatment with vitamin D because of the risk of high magnesium levels
  • phosphorus containing products in large doses. As these in large doses increase the risk of high phosphate blood levels.
