Colecalciferol is Vitamin D3, a form of vitamin D that your body needs to absorb calcium and keep your bones strong. It works by boosting the level of vitamin D in your body, especially when you are not getting enough from sunlight or food.

Explore this drug
For adults with vitamin D deficiency, the usual dose is 1,000 to 5,000 IU daily or as your doctor prescribes. Take it with food, especially a meal that has some fat or oil in it, because this helps your body absorb it better. Your doctor may give you a higher weekly dose depending on how low your vitamin D level is.
If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed one and continue as normal. Do not take a double dose to make up for the one you missed.
Buy only from reputable pharmacies — do not purchase vitamin D products from roadside vendors or unregistered sellers, as fake supplements are common. Do not take more than the recommended dose thinking it will work faster, as too much vitamin D can be dangerous. If your doctor asked you to do a blood test to check your vitamin D level, make sure you follow up so the dose can be adjusted properly.
Thiazide diuretics (water tablets for blood pressure) can cause calcium levels to go too high when combined with vitamin D3. Antacids or supplements containing magnesium or aluminium can affect how well your body absorbs it. If you are taking epilepsy drugs like phenytoin or carbamazepine, they can reduce the effect of vitamin D3, so your doctor may increase your dose.
