United Home Calactate Drug Interactions

The following interactions should be considered before giving this medicine.
Calcium enhances the effects of digitalis glycosides on the heart and may precipitate digitalis intoxication.
Hypercalcemia has occurred when calcium salts are given with thiazide diuretics or vitamin D. Concomitant ingestion of calcium salts and thiazide diuretics may predispose patients to developing the milk-alkali syndrome.
Calcium salts reduce the absorption of other medicines such as bisphosphonates (e.g., alendronate), fluoride, some fluoroquinolones and tetracyclines, levothyroxine, and phenytoin; doses should be separated by at least three hours.
Concomitant intake with calcium may also result in decreased effectiveness of other medicines such as aspirin, bismuth subcitrate, calcium channel blockers, and cefpodoxime; and decreased bioavailability of atenolol.
Calcium may reduce the absorption of other minerals such as iron and zinc; doses should be separated by at least two hours.
Alcohol, aluminum-containing antacids, mineral oil, stimulant laxatives (prolonged use), and corticosteroids reduce calcium absorption. Anticonvulsants may also reduce serum calcium levels.
Foods rich in oxalic acid (spinach, sweet potatoes, and beans) or phytic acid (unleavened bread, raw beans, seeds, nuts, and grains) may also result in decreased calcium absorption. High intakes of caffeine affect the bioavailability of calcium by increasing calcium loss in urine and stimulating calcium secretion into the GI tract.
Tell the doctor about other medicines the patient is taking including supplements and herbal products.
