What should I discuss with my healthcare provider before taking ergocalciferol (Calcidol, Calciferol, Drisdol, Vitamin D2)?

Do not use this medication if you have ever had an allergic reaction to vitamin D, or if you have:

  • high levels of calcium in your blood (hypercalcemia);
  • high levels of vitamin D in your body (hypervitaminosis D); or
  • any condition that makes it hard for your body to absorb nutrients from food (malabsorption).

To make sure you can safely take ergocalciferol, tell your doctor if you have any of these other conditions:

  • heart disease;
  • coronary artery disease;
  • kidney disease; or

How should I take ergocalciferol (Calcidol, Calciferol, Drisdol, Vitamin D2)?

Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

Your doctor may occasionally change your dose to make sure you get the best results.

Measure liquid medicine with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.

To be sure this medication is helping your condition, your blood will need to be tested often. You may also need x-rays. Visit your doctor regularly.

Ergocalciferol is only part of a complete program of treatment that may also include other medications and a special diet. It is very important to follow the medication and diet plan created for you by your doctor or nutrition counselor. You should become very familiar with the list of foods you must eat or avoid to help control your condition.
