2.1 Dosage in

Adults The determination of dosage and duration for any particular patient must take into consideration the severity and nature of the infection, the susceptibility of the causative microorganism, the integrity of the patient’s host-defense mechanisms, and the status of renal and hepatic function. CIPRO Tablets or CIPRO for Oral Suspension may be administered to adult patients when clinically indicated at the discretion of the physician. Administer CIPRO for Oral Suspension using the co-packaged graduated spoon.

Table 1: Adult Dosage Guidelines Infection Dose Frequency Usual Durations Generally ciprofloxacin should be continued for at least 2 days after the signs and symptoms of infection have disappeared, except for inhalational anthrax (post-exposure).

2.2 Dosage in

Pediatric Patients Dosing and initial route of therapy (that is, IV or oral) for cUTI or pyelonephritis should be determined by the severity of the infection. CIPRO should be administered as described in Table 3. Administer CIPRO for Oral Suspension using the co-packaged graduated spoon.

Table 3: Pediatric Dosage Guidelines Infection Dose Frequency Total Duration Complicated Urinary Tract or Pyelonephritis (patients from 1 to 17 years of age) 10 mg/kg to 20 mg/kg (maximum 750 mg per dose; not to be exceeded even in patients weighing more than 51 kg) Every 12 hours 10–21 days 1 Inhalational Anthrax (Post-Exposure) 2 15 mg/kg (maximum 500 mg per dose) Every 12 hours 60 days Plague 2,3 15 mg/kg (maximum 500 mg per dose) Every 8 to 12 hours 14 days 1 The total duration of therapy for cUTI and pyelonephritis in the clinical trial was determined by the physician. The mean duration of treatment was 11 days (range 10 to 21 days). 2 Begin drug administration as soon as possible after suspected or confirmed exposure. 3 Begin drug administration as soon as possible after suspected or confirmed exposure to Y. pestis.

2.3 Dosage Modifications in

Patients with Renal Impairment Ciprofloxacin is eliminated primarily by renal excretion; however, the drug is also metabolized and partially cleared through the biliary system of the liver and through the intestine. These alternative pathways of drug elimination appear to compensate for the reduced renal excretion in patients with renal impairment. Nonetheless, some modification of dosage is recommended, particularly for patients with severe renal dysfunction. Dosage guidelines for use in patients with renal impairment are shown in Table 4.

Table 4: Recommended Starting and Maintenance Doses for Adult Patients with Impaired Renal Function Creatinine Clearance (mL/min) Dose > 50 See Usual Dosage. 30–50 250–500 mg every 12 hours 5–29 250–500 mg every 18 hours Patients on hemodialysis or Peritoneal dialysis 250–500 mg every 24 hours (after dialysis) When only the serum creatinine concentration is known, the following formulas may be used to estimate creatinine clearance: Men - Creatinine clearance (mL/min) = Weight (kg) x (140–age) 72 x serum creatinine (mg/dL) Women - 0.85 x the value calculated for men. The serum creatinine should represent a steady state of renal function. In patients with severe infections and severe renal impairment, a unit dose of 750 mg may be administered at the intervals noted above. Patients should be carefully monitored. Pediatric patients with moderate to severe renal insufficiency were excluded from the clinical trial of cUTI and pyelonephritis. No information is available on dosing adjustments necessary for pediatric patients with moderate to severe renal insufficiency (that is, creatinine clearance of < 50 mL/min/1.73m 2 ).

2.4 Important

Administration Instructions With Multivalent Cations Administer CIPRO at least 2 hours before or 6 hours after magnesium/aluminum antacids; polymeric phosphate binders (for example, sevelamer, lanthanum carbonate) or sucralfate; Videx ® (didanosine) chewable/buffered tablets or pediatric powder for oral solution; other highly buffered drugs; or other products containing calcium, iron or zinc. With Dairy Products Concomitant administration of CIPRO with dairy products (like milk or yogurt) or calcium-fortified juices alone should be avoided since decreased absorption is possible; however, CIPRO may be taken with a meal that contains these products. Hydration of Patients Receiving CIPRO Assure adequate hydration of patients receiving CIPRO to prevent the formation of highly concentrated urine. Crystalluria has been reported with quinolones. Instruct the patient of the appropriate CIPRO administration. Missed Doses If a dose is missed, it should be taken anytime but not later than 6 hours prior to the next scheduled dose. If less than 6 hours remain before the next dose, the missed dose should not be taken and treatment should be continued as prescribed with the next scheduled dose. Double doses should not be taken to compensate for a missed dose. Splitting CIPRO Tablets CIPRO Tablets, 250 mg and 500 mg are functionally scored tablets which can be split into one-half at the scored line to provide a 125 mg and 250 mg strength, respectively.

2.5 Directions for

Reconstitution of the CIPRO Microcapsules for Oral Suspension CIPRO Oral Suspension is supplied in 5% (5 g ciprofloxacin in 100 mL) and 10% (10 g ciprofloxacin in 100 mL) strengths. CIPRO oral suspension is composed of two components (microcapsules and diluent) that must be combined prior to dispensing.

Table 5: Appropriate Dosing Volumes of the Reconstituted Oral Suspensions Dose 5% (250 mg/5 mL) 10% (500 mg/5 mL) 250 mg 5 mL 2.5 mL 500 mg 10 mL 5 mL 750 mg 15 mL 7.5 mL Preparation of the suspension: Step1 The small bottle contains the microcapsules, the large bottle contains the diluent. Step 2 Open both bottles.

Child-proof cap: Press down according to instructions on the cap while turning to the left. Step 3 Pour the microcapsules completely into the larger bottle of diluent. Do not add water to the suspension. Step 4 Remove the top layer of the diluent bottle label (to reveal the CIPRO Oral Suspension label). Close the large bottle completely according to the directions on the cap and shake vigorously for about 15 seconds. The suspension is ready for use.

Step 5: Write the expiration date of the re-constituted oral suspension on the bottle label. Reconstituted product may be stored below 30°C (86°F) for 14 days. Protect from freezing. No additions should be made to the mixed final ciprofloxacin suspension. CIPRO Oral Suspension should not be administered through feeding or NG (nasogastric) tubes due to its physical characteristics. Step 1 Step 2 Step 3 Step 4
