HOW SHOULD THIS MEDICINE BE USED?
Drisdol® (ergocalciferol, USP) capsules should be taken exactly as prescribed by your doctor. Your dosage is based on your medical condition, diet, age, and response to treatment.
Vitamin D should not be given to infants that have high levels of calcium.
KEEP DRISDOL CAPSULES OUT OF REACH OF CHILDREN
Drisdol capsules are best absorbed when taken with or after a meal, but they may be taken with or without food.
Certain medications can increase the absorption of vitamin D. Ask your doctor or pharmacist if any other medications or over-the-counter supplements or herbal preparations will affect absorption of Drisdol capsules and if so, ask your doctor or pharmacist for an appropriate dosing schedule. Make sure that you tell your doctor about all prescription and over-the-counter medicines, and herbal and dietary supplements that you are taking.
In addition, you can be receiving vitamin D from other sources including fortified foods. Make sure that you tell your doctor about any fortified foods that you may be taking.
If you are taking Drisdol capsules for the treatment of vitamin D resistant rickets, you should be aware that there is a very narrow range in the dose you can receive where it will help you, before the dose is toxic to your body.
Your doctor will monitor the phosphorus levels in your body and may prescribe supplementation to maintain normal phosphorus levels.
Excessive vitamin D during pregnancy has been shown to cause fetal abnormalities. You should avoid vitamin D in doses above the recommended dietary amount unless your doctors believes that the benefit clearly outweighs the risk of taking the medicine.
Your doctor will only prescribe Drisdol capsules (and with caution) if you are nursing, as large doses of vitamin D have been shown to pass through to breast milk.
The dose of vitamin D given to children must be individualized for each patient.
Older patients may absorb vitamin D more quickly than younger patients. If you are older, your doctor may start you on a low dose of Drisdol capsules and slowly increase your dose based on your response.
