Patient leaflet - Fultium-D3 3 200 IU capsules

1. What Fultium-D3 is and what it is taken for

Fultium- D3 are soft capsules. They contain the active ingredient:

  • Vitamin D3 (3,200 IU colecalciferol equivalent to 80 micrograms Vitamin D3).

Vitamin D is found in the diet and is also produced in the skin after exposure to the sun. Often vitamin D is given in combination with calcium. Fultium-D3 is recommended for use when you have a normal intake of dietary calcium.

Fultium-D3 may be prescribed by your doctor to treat or prevent vitamin D deficiency.

Deficiency of vitamin D may occur when your diet or lifestyle does not provide you enough vitamin D or when your body requires more vitamin D (for instance when you are pregnant). Fultium-D3 may also be prescribed for certain bone conditions, such as thinning of the bone (osteoporosis) when it will be given to you with other medicines.

2. Before you take Fultium-D3

Do not take Fultium-D3 if you

  • are allergic (hypersensitive) to vitamin D or any of the other ingredients in the capsules (these are listed in section 6, Further information).
  • have high levels of vitamin D in your blood (hypervitaminosis D).
  • have high blood levels of calcium (hypercalcaemia) or high urine levels of calcium (hypercalciuria)
  • have kidney stones or serious kidney problems.

Check with your doctor before taking Fultium-D3 if

  • you have kidney damage or disease.

    Your doctor may want to measure the levels of calcium in your blood

    or urine.

  • you are being treated for heart disease.
  • you have sarcoidosis (an immune system disorder which may affect your liver, lungs, skin or lymph nodes).
  • you are already taking additional doses of calcium or vitamin D. Whilst you are taking Fultium-D3 your doctor will monitor your blood levels of calcium to make sure they are not too high.

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

In particular the following medicines may interact with Fultium-D3:

  • Heart medicines (cardiac glycosides such as digoxin). Your doctor may monitor your heart with an electrocardiogram (ECG) and measure the levels of calcium in your blood.
  • Medicines to treat epilepsy (such as phenytoin) or medicines to make you sleep (barbiturates such as phenobarbitone) as these medicines can decrease the effect of vitamin D.
  • Glucocorticoids (steroid hormones such as hydrocortisone or prednisolone).
  • These can decrease the effect of vitamin D.
  • Laxatives (such as paraffin oil) or a cholesterol lowering drug called colestyramine may reduce the absorption of vitamin D.
  • Actinomycin (a medicine used to treat some forms of cancer) and imidazole antifungals (medicines such as clotrimazole and ketoconazole used to treat fungal diseases) as they may interfere

    with the metabolism of vitamin D.

    Taking Fultium-D3 with food and drink

    You can take Fultium-D3 with or without food and drink.

    Pregnancy and breast-feeding

    If you are pregnant or think you may be pregnant or you are breast-feeding you should talk to your doctor or pharmacist before you take Fultium-D3. Fultium-D3 should be used during pregnancy and breast-feeding only if recommended by your doctor.

    Driving and using machines

    Fultium- D3 should not affect your ability to drive or operate machinery.

3. How to take Fultium-D3

Dose

In severe vitamin D deficiency (for adolescents, adults and the elderly)

Your doctor will usually prescribe you a dose of 1 capsule daily for up to 12 weeks.

The amount will depend on how low your vitamin D levels are and how you respond to treatment.

Your doctor will then tell you to take 1-2 capsules weekly to maintain your vitamin D levels.

In moderate vitamin D deficiency (for adults and the elderly) or to prevent vitamin D deficiency

Your doctor will usually prescribe 1-2 capsules weekly.

1 capsule daily for up to 12 weeks.

If you take more Fultium-D3 than you should

If you accidentally take one capsule too many, nothing is likely to happen. If you accidentally take several capsules too many tell your doctor or get other medical advice immediately. If possible, take the capsules, the box and this leaflet with you to show the doctor. If you take too many capsules you may feel or be sick, become constipated or have stomach pains, weak muscles, tiredness, lack of appetite, kidney problems and in severe cases irregular heartbeats.

If you forget to take Fultium-D3

If you forget to take your capsules, take them as soon as you can. Do not take a double dose to make up for a forgotten dose. After that, take the next capsule in accordance with the instructions given to you by your doctor.
