Desunin tablets contain the active ingredient colecalciferol, which is also known as vitamin D3. Each tablet contains 800 IU colecalciferol, which is equivalent to 20 micrograms vitamin D3.
What is it used for?
- Prevention and treatment of vitamin D deficiency in adults and adolescents over 12 years of age.
How does it work?
- Desunin tablets contain the active ingredient colecalciferol, which is also known as vitamin D3. Each tablet contains 800 IU colecalciferol, which is equivalent to 20 micrograms vitamin D3.
- Vitamin D is normally obtained primarily from sunlight acting on the skin. It is also consumed in the diet in oily fish and dairy products. Vitamin D deficiency develops when there is inadequate exposure to sunlight, such as in elderly people with reduced mobility or who are housebound, people who cover their skin when outdoors, or when there is a lack of the vitamin in the diet.
- Vitamin D is needed for calcium to be absorbed from the gut, and deficiency can lead to low calcium levels and subsequent weakening of bones. This is known as osteomalacia.
How do I take it?
- Desunin tablets can be taken either with or without food. The tablets should be swallowed with a drink of water. They may also be crushed.
- Desunin tablets are usually taken once daily.
- The number of tablets to be taken each day will vary from person to person and depends on the severity of vitamin D deficiency. It is important to follow the instructions given by your doctor. These will be printed on the dispensing label that your pharmacist has put on the medicine.

Pregnancy and breastfeeding
Certain medicines should not be used during pregnancy or breastfeeding. However, other medicines may be safely used in pregnancy or breastfeeding providing the benefits to the mother outweigh the risks to the unborn baby. Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.
- This medicine is safe to take during pregnancy to treat an established vitamin D deficiency. It is important to let your doctor know if you are pregnant and to follow the instructions given by your doctor for how many tablets to take each day. You should not take other vitamin D supplements in combination with this one.
- Pregnant and breastfeeding women who don’t have an established vitamin D deficiency should not take this medicine to prevent vitamin D deficiency, as the dose of vitamin D in Desunin tablets is too high for this purpose. It is recommended that women who are pregnant or breastfeeding should take a daily vitamin D supplement containing 10 micrograms of vitamin D to prevent vitamin D deficiency. Ask your doctor or pharmacist for advice on suitable products.
- Vitamin D passes into breast milk. This medicine is safe for mothers who are breastfeeding to take to treat an established vitamin D deficiency. However, if you have been prescribed a particularly high dose your doctor may want to monitor the nursing infant’s calcium levels. You should not take other vitamin D supplements in combination with this one. You should also talk to your doctor before giving any vitamin D supplements to your baby, as they may be getting enough from your milk.

If you are taking a thiazide diuretic in combination with this medicine you should have regular blood tests to monitor the level of calcium in your blood.
People taking digoxin or other cardiac glycosides may have an increased risk of abnormal heart rhythms if they experience abnormally high blood calcium levels while taking this medicine.
