                Hypercalcemia

                Hypervitaminosis D

                Ergocalciferol (oral): Gastrointestinal (GI), liver, or biliary disease associated with malabsorption of vitamin D analogues

                Documented hypersensitivity with drugs that could have allergenic crossreactivity with ergocalceferol

                Cautions

                Ergocalciferol: Use with caution in renal impairment (strong caution), heart disease, kidney stones, arteriosclerosis

                Obtain serum calcium twice weekly during titration

                Discontinue if patient becomes hypercalcemic

                Presence of tartrazine in some products may cause allergic reactions

                Vitamin D toxicity may last ≥2 months after therapy is discontinued

                Restrict intake in infants with idiopathic hypercalcemia

                Concurrent use of cardiac glycosides

                Adequate clinical response to vitamin D therapy is dependent on adequate dietary calcium

                Maintain normal serum phosphorous concentrations in patients treated for hyperphosphatemia to prevent metastatic calcification

                When treating hypoparathyroidism, concomitant treatment with intravenous calcium, parathyroid hormone, and/or dihydrotachysterol may also be required

                Adults with a body mass index (BMI) greater than 30 kg/m² are at high risk for vitamin D deficiency due to storage of vitamin D in adipose tissue; doses higher than recommended daily allowance may be required, but must be carefully monitored to avoid toxicity

                Metabolism of vitamin D may be altered in patients with chronic kidney disease

                In renal impairment, supplementation with ergocalciferol may be necessary; monitor closely

                In patients with rickets, the range between therapeutic and toxic doses is narrow in vitamin D–resistant patients; adjust dose based on clinical response to avoid toxicity

                Pregnancy Categories

                A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

                B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

                C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

                D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

                X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

                cholecalciferol (vitamin D3) oral

                VITAMIN D - ORAL

                COMMON BRAND NAME(S): Calciferol, Drisdol

                USES: Vitamin D (ergocalciferol-D2, cholecalciferol-D3, alfacalcidol) is a fat-soluble vitamin that helps your body absorb calcium and phosphorus. Having the right amount of vitamin D, calcium, and phosphorus is important for building and keeping strong bones. Vitamin D is used to treat and prevent bone disorders (such as rickets, osteomalacia). Vitamin D is made by the body when skin is exposed to sunlight. Sunscreen, protective clothing, limited exposure to sunlight, dark skin, and age may prevent getting enough vitamin D from the sun.Vitamin D with calcium is used to treat or prevent bone loss (osteoporosis). Vitamin D is also used with other medications to treat low levels of calcium or phosphate caused by certain disorders (such as hypoparathyroidism, pseudohypoparathyroidism, familial hypophosphatemia). It may be used in kidney disease to keep calcium levels normal and allow normal bone growth. Vitamin D drops (or other supplements) are given to breast-fed infants because breast milk usually has low levels of vitamin D.

                HOW TO USE: Take vitamin D by mouth as directed. Vitamin D is best absorbed when taken after a meal but may be taken with or without food. Alfacalcidol is usually taken with food. Follow all directions on the product package. If you have any questions, ask your doctor or pharmacist.If your doctor has prescribed this medication, take as directed by your doctor. Your dosage is based on your medical condition, amount of sun exposure, diet, age, and response to treatment.If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.If you are taking the chewable tablet or wafers, chew the medication thoroughly before swallowing. Do not swallow whole wafers.If you are taking the rapidly-dissolving tablets, dry your hands before handling the medication. Place each dose on the tongue, allow it to dissolve completely, and then swallow it with saliva or water. You do not need to take this medication with water.Certain medications (bile acid sequestrants such as cholestyramine/colestipol, mineral oil, orlistat) can decrease the absorption of vitamin D. Take 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 how long you should wait between doses and for help finding a dosing schedule that will work with all your medications.Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day if you are taking it once a day. If you are taking this medication only once a week, remember to take it on the same day each week. It may help to mark your calendar with a reminder.If your doctor has recommended that you follow a special diet (such as a diet high in calcium), it is very important to follow the diet to get the most benefit from this medication and to prevent serious side effects. Do not take other supplements/vitamins unless ordered by your doctor.If you think you may have a serious medical problem, get medical help right away.

                SIDE EFFECTS: Vitamin D at normal doses usually has no side effects. If you have any unusual effects, contact your doctor or pharmacist promptly.If your doctor has directed you to use this medication, remember that your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Too much vitamin D can cause harmful high calcium levels. Tell your doctor right away if any of these signs of high vitamin D/calcium levels occur: nausea/vomiting, constipation, loss of appetite, increased thirst, increased urination, mental/mood changes, unusual tiredness.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects.
