Zemplar Oral Warnings
Zemplar Oral Uses
Paricalcitol is used to treat and prevent high levels of a certain natural substance made by the body (parathyroid hormone) in patients with long-term kidney disease. In these patients, the high level of parathyroid hormone is caused by a low level of calcium and a certain kind of vitamin D. Too much parathyroid hormone can cause serious problems such as bone disorders. Paricalcitol is a man-made form of vitamin D. It helps to reduce parathyroid hormone levels and may help your body absorb calcium and phosphorus.How to use Zemplar Oral

If you are currently using any of the medications listed above, tell your doctor or pharmacist before starting paricalcitol.
Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially: products that contain aluminum (e.g., certain antacids, phosphate binders), corticosteroids (e.g., prednisone), digoxin, drugs affecting liver enzymes that remove paricalcitol from your body (such as azole antifungals including ketoconazole/itraconazole, macrolide antibiotics including clarithromycin, nefazodone, HIV protease inhibitors including indinavir/ritonavir), thiazide diuretics (e.g., hydrochlorothiazide).
Check the labels on all your prescription and nonprescription/herbal products (e.g., antacids, vitamins) because they may contain aluminum, calcium, phosphate, or vitamin D. Ask your pharmacist about using those products safely.
Certain medications can decrease the absorption of vitamin D (bile acid sequestrants such as cholestyramine/colestipol, mineral oil, orlistat). Therefore, separate your doses of these medications as far as possible from your doses of vitamin D (at least 2 hours apart, longer if possible). It may be easiest to take vitamin D at bedtime if you are also taking these other medications. Ask your doctor or pharmacist about how long you should wait between doses and for help finding a dosing schedule that will work with all your medications.
