Explanation Required
- Calcium
Short-term treatment with risedronate in people with hyperparathydoidism—a disorder characterized by high blood levels of calcium—resulted in lower calcium blood levels. Additional research is needed to determine whether people taking risedronate for Paget’s disease might develop low blood calcium levels. As a precaution, people with Paget’s disease should take supplemental calcium and vitamin D if dietary intake is inadequate. However, taking risedronate at the same time as calcium supplements reduces absorption of the drug. Therefore, people taking risedronate for Paget’s disease should take calcium supplements an hour before or two hours after taking the drug.
The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence. - Magnesium
Taking risedronate at the same time as iron, zinc, or magnesium may reduce the amount of drug absorbed. Therefore, people taking risedronate who wish to supplement with these minerals should take them an hour before or two hours after the drug.
