every 24 hours

3 Days

Complicated Urinary Tract Infection and Acute Uncomplicated Pyelonephritis

1000 mg

every 24 hours

7–14 Days

Patients whose therapy is started with CIPRO IV for UTIs may be switched to CIPRO XR when clinically indicated at the discretion of the physician.


CIPRO XR tablets should be taken whole and not split, crushed, or chewed.
CIPRO XR should be administered at least 2 hours before or 6 hours after antacids containing magnesium or aluminum, polymeric phosphate binders (for example, sevelamer, lanthanum carbonate), as well as sucralfate, VIDEX® (didanosine) chewable/buffered tablets or pediatric powder, other highly buffered drugs, metal cations such as iron, and multivitamin preparations with zinc [see Drug Interactions (7)].
Concomitant administration of Cipro XR with dairy products (like milk or yogurt) or with calcium-fortified products alone should be avoided since decreased absorption is possible. A 2-hour window between substantial calcium intake (greater than 800 mg) and dosing with CIPRO XR is recommended [see Patient Counseling Information (17)].

Adequate hydration of patients receiving CIPRO XR should be maintained to prevent the formation of highly concentrated urine. Crystalluria has been reported with quinolones [see Warnings and Precautions (5.12), Adverse Reactions (6.1) and Patient Counseling Information (17)].

Impaired Renal Function

In patients with cUTI and acute uncomplicated pyelonephritis with a creatinine clearance of ≤ 30 mL/min, the dose of CIPRO XR should be reduced from 1000 mg to 500 mg daily. The use of Ciprofloxacin 1000 mg XR tablets is not recommended in this patient population.
For patients on hemodialysis or peritoneal dialysis, administer CIPRO XR after the dialysis procedure is completed (maximum dose should be Ciprofloxacin 500 mg XR every 24 hours). The use of Ciprofloxacin 1000 mg XR is not recommended in this patient population. [See Use in Specific Populations (8.6) and Clinical Pharmacology (12.3).]
For patients on continuous ambulatory peritoneal dialysis (CAPD), the maximum dose should be 500 mg every 24 hours.
