MONITOR: Coadministration of bisphosphonates and loop diuretics may potentiate the risk of hypocalcemia. Bisphosphonates alone often cause mild, asymptomatic hypocalcemia via inhibitive effects on bone resorption and possibly chelation of blood calcium. These effects may be additive with those of loop diuretics, which tend to increase the urinary excretion of calcium.
MANAGEMENT: Caution is advised if bisphosphonates are coadministered with loop diuretics. Renal function as well as serum calcium levels should be monitored during and after treatment, since the effects of bisphosphonates can continue for many weeks after discontinuation. Patients and clinicians should be alert to signs and symptoms of clinical hypocalcemia such as muscle spasm, carpopedal spasm, laryngeal spasm, tetany, convulsions, mental changes (irritability, depression, psychosis), increased intracranial pressure, papilledema, QT interval prolongation, and cardiac arrhythmias.

Drug Interaction Classification
The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
| Major | Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. |
| Moderate | Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. |
| Minor | Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. |
