Colecalciferol

About colecalciferol

Colecalciferol is a fat-soluble vitamin which works by replacing deficiency. Deficiency is caused by inadequate exposure to sunlight and low consumption of foods containing colecalciferol. The best natural sources are found in oily fish (sardine, herring, salmon and tuna), liver, dairy products and egg yolks.

Symptoms of long term colecalciferol deficiency are low blood levels of calcium and phosphate, which result in the softening of the bones. In children this can cause abnormal bone development and in adults it can cause osteoporosis, backache, muscle weakness, bone pain and fractures.

Before taking colecalciferol

Before taking colecalciferol make sure your doctor or pharmacist knows:

• If you are pregnant, trying for a baby or breast-feeding.
• If you suffer from kidney or heart problems.
• If you know you have high levels of calcium in the blood or urine.
• If you have ever had an allergic reaction to this or any other medicine or tablet ingredient.
• If you suffer from sarcoidosis (a disease resulting from inflammation).
• If you are taking any other medicines, including those available to buy without a prescription, herbal or complementary medicines.

How to take colecalciferol

• Take your medication exactly as directed by your doctor.
• Always read the manufacturer's information leaflet, if possible before beginning treatment.
• If you are taking the tablets, crush or chew before swallowing with a drink of water.
• If you are taking the powder or the effervescent granules, pour the contents of the sachet into non-carbonated water, stir and drink immediately.
• Never take more than the prescribed dose. If you suspect that you or someone else has taken an overdose of colecalciferol contact your doctor or go to the accident and emergency department of your local hospital. Where possible take the container with you, even if it is empty.

Getting the most from your treatment

• Before taking any 'over-the-counter' medicines, check with your pharmacist which medicines are safe for you to take alongside colecalciferol.
• Keep your regular appointments with your doctor so your progress can be monitored.
• If you forget to take a dose, take one as soon as you remember unless it is nearly time to take the next one. Never take two doses together.
