Doxercalciferol is used to treat secondary hyperparathyroidism (a condition in which the body produces too much parathyroid hormone [PTH; a natural substance needed to control the amount of calcium in the blood]) in certain people with chronic kidney disease and in those treated with dialysis (medical treatment to clean the blood when the kidneys are not working properly). Doxercalciferol is in a class of medications called vitamin D analogs. It works by helping the body to use more of the calcium found in foods or supplements and by regulating the body's production of parathyroid hormone.
Doxercalciferol comes as a capsule to take by mouth. For people receiving dialysis treatments, it is usually taken three times weekly at dialysis sessions. For people with chronic kidney disease who are not receiving dialysis treatments, it is usually taken once daily. Take doxercalciferol at around the same time on the appropriate days. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take doxercalciferol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may change your dose depending on your body's response to doxercalciferol.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
Before taking doxercalciferol,
Doxercalciferol will work only if you also get the right amount of calcium from the foods you eat. If you get too much calcium from foods, you may experience serious side effects from taking doxercalciferol. If you do not get enough calcium from foods, doxercalciferol will not control your condition. Your doctor will tell you which foods are good sources of calcium and how many servings you need each day. If you find it difficult to eat enough of these foods, tell your doctor. In that case, your doctor can prescribe or recommend a calcium supplement.
Your doctor may also prescribe a low-phosphate diet during your treatment with doxercalciferol. Follow these directions carefully.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( Web Site) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site
