A patient who is taking calcium supplements receives a prescription for ciprofloxacin (Cipro) for a urinary tract infection. The nurse will teach this patient to:
a. consume extra fluids while taking the ciprofloxacin to prevent hypercalciuria.
b. stop taking the calcium supplements while taking the ciprofloxacin.
c. take the two medications together to increase the absorption of both.
d. take the calcium either 6 hours before or 2 hours after taking the ciprofloxacin.
ANS: D
Cationic compounds, including calcium supplements, can reduce the absorption of ciprofloxacin so proper interval dosing is necessary. Consuming extra fluids is not indicated. With proper interval dosing, it is not necessary to discontinue the calcium while giving the ciprofloxacin. These two medications should not be given together.
