Potential Negative Interaction
- Calcium
People with kidney failure may develop high blood levels of calcium while taking calcium acetate. Since calcium acetate is a source of supplemental calcium, people taking the drug should avoid taking additional calcium supplements. People experiencing adverse effects of high blood calcium—such as loss of appetite, mental depression, poor memory, and muscle weakness—should notify their healthcare practitioner.
- Magnesium
Calcium-containing antacids, when taken together with calcium acetate, may result in abnormally high blood levels of calcium. Consequently, people taking calcium acetate should avoid taking calcium-containing antacids.
Explanation Required
- Zinc
People with renal failure or on hemodialysis often have low blood levels of zinc, which may produce symptoms such as abnormal taste or smell, reduced sexual functions, and poor immunity. One controlled study showed that taking zinc at the same time as calcium acetate reduces absorption of zinc. Therefore, people should avoid taking calcium acetate and zinc supplements together. Another controlled study revealed that neither short-term nor long-term treatment with calcium acetate results in reduced blood zinc levels. Thus, while calcium acetate reduces the amount of zinc absorbed from supplements, long-term treatment with the drug does not appear to affect overall zinc status. However, people with renal failure who experience symptoms of zinc deficiency might benefit from supplementing with zinc, regardless of whether or not they take calcium acetate.
