PHONETIC PRONUNCIATION:

COMMON BRAND NAME(S): Citracal + D, Os-Cal, Oyster Shell + D

GENERIC NAME(S): calcium carbonate/ergocalciferol (vitamin D2)

Uses

USES: This combination medication is used to prevent or treat low blood calcium levels in people who do not get enough calcium from their diets. It may be used to treat conditions caused by low calcium levels such as bone loss (osteoporosis), weak bones (osteomalacia/rickets), decreased activity of the parathyroid gland (hypoparathyroidism), and a certain muscle disease (latent tetany). It may also be used in certain patients to make sure they are getting enough calcium (e.g., women who are pregnant, nursing, or postmenopausal, people taking certain medications such as phenytoin, phenobarbital, or prednisone). Calcium plays a very important role in the body. It is necessary for normal functioning of nerves, cells, muscle, and bone. If there is not enough calcium in the blood, then the body will take calcium from bones, thereby weakening bones. Vitamin D helps your body absorb calcium and phosphorus. Having the right amounts of vitamin D, calcium, and phosphorus is important for building and keeping strong bones.


How to use CALCIUM SUPPLEMENT/VITAMIN D - ORAL

HOW TO USE: Take this medication by mouth with food. If your product contains calcium citrate, then it may be taken with or without food. Follow all directions on the product package, or take as directed by your doctor. For best absorption, if your total daily dose is more than 600 milligrams, then divide your dose and space it throughout the day. If you are uncertain about any of the information, consult your doctor or pharmacist. 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 form of this medication, chew thoroughly before swallowing. If you are taking capsules, swallow each capsule whole. Do not crush or chew extended-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing. Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day. If your doctor has recommended that you follow a special diet, 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. Calcium supplements come in different forms that contain different amounts of calcium/vitamin D. Ask your doctor or pharmacist to help select the best product for you. If you think you may have a serious medical problem, seek immediate medical attention.

Tell your doctor right away if any of these unlikely but serious side effects occur: nausea/vomiting, loss of appetite, unusual weight loss, mental/mood changes, signs of kidney problems (such as change in the amount of urine), bone/muscle pain, headache, increased thirst, increased urination, weakness, tiredness, fast/pounding heartbeat.

Interactions

DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval. Some products that may interact with this drug include: digoxin, phosphate binders. Calcium can decrease the absorption of other drugs such as tetracycline antibiotics (e.g., doxycycline, minocycline), bisphosphonates (e.g., alendronate), estramustine, levothyroxine, and quinolone antibiotics (e.g., ciprofloxacin, levofloxacin). Also, 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 calcium/vitamin D. 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. Check the labels on all your prescription and nonprescription/herbal products (e.g., antacids, laxatives, vitamins) because they may contain calcium, phosphate, or vitamin D. Ask your pharmacist about using those products safely. Vitamin D is very similar to calcitriol. Do not use medications containing calcitriol while using vitamin D. This medication may interfere with certain laboratory tests (including cholesterol tests), possibly causing false test results. Make sure laboratory personnel and all your doctors know you use this drug.
