Dosage of Ciprofloxacin in details
Ciprofloxacin XR and Ciprofloxacin immediate-release tablets are not interchangeable. Ciprofloxacin XR should be administered orally once daily (Table 1).
Patients whose therapy is started with Ciprofloxacin IV for UTIs may be switched to Ciprofloxacin XR when clinically indicated at the discretion of the physician.
- Ciprofloxacin XR tablets should be taken whole and not split, crushed, or chewed.
- Ciprofloxacin 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.
- Concomitant administration of Ciprofloxacin 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 Ciprofloxacin XR is recommended.
Adequate hydration of patients receiving Ciprofloxacin XR should be maintained to prevent the formation of highly concentrated urine. Crystalluria has been reported with quinolones.
Impaired Renal Function
- In patients with cUTI and acute uncomplicated pyelonephritis with a creatinine clearance of ≤ 30 mL/min, the dose of Ciprofloxacin 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 Ciprofloxacin 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.
- For patients on continuous ambulatory peritoneal dialysis (CAPD), the maximum dose should be 500 mg every 24 hours.
What other drugs will affect Ciprofloxacin?
Tell your doctor about all medicines you use, and those you start or stop using during your treatment with ciprofloxacin, especially:
glyburide, methotrexate, metoclopramide, phenytoin, probenecid, theophylline;
a blood thinner (warfarin, Coumadin, Jantoven);
a diuretic or "water pill";
heart rhythm medication--amiodarone, disopyramide, dofetilide, dronedarone, procainamide, quinidine, sotalol, and others;
medicine to treat depression or mental illness--amitriptylline, clomipramine, desipramine, iloperidone, imipramine, nortriptyline, thioridazine, ziprasidone, and others; or
NSAIDs (nonsteroidal anti-inflammatory drugs)--aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib, diclofenac, indomethacin, meloxicam, and others.
This list is not complete. Other drugs may interact with ciprofloxacin, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed in this medication guide.
Some quinolones, including ciprofloxacin, have also been shown to interfere with the metabolism of caffeine. This may lead to reduced clearance of caffeine and a prolongation of its serum half-life.
Some quinolones, including ciprofloxacin, have been associated with transient elevations in serum creatinine in patients receiving cyclosporine concomitantly.
The concomitant administration of ciprofloxacin with the sulfonylurea glyburide has, on rare occasions, resulted in severe hypoglycemia.
Histamine H2-receptor antagonists
Histamine H2-receptor antagonists appear to have no significant effect on the bioavailability of ciprofloxacin.
Renal tubular transport of methotrexate may be inhibited by concomitant administration of ciprofloxacin, potentially leading to increased plasma levels of methotrexate. This might increase the risk of methotrexate toxic reactions. Therefore, patients under methotrexate therapy should be carefully monitored when concomitant ciprofloxacin therapy is indicated.
Multivalent Cation-Containing Products
Concurrent administration of a quinolone, including ciprofloxacin, with multivalent cation-containing products such as magnesium or aluminum antacids, sucralfate, VIDEX chewable/buffered tablets or pediatric powder, or products containing calcium, iron, or zinc may substantially decrease the absorption of ciprofloxacin, resulting in serum and urine levels considerably lower than desired. Proquin XR should be administered at least 4 hours before or 2 hours after these products. This time window is different than for other oral formulations of ciprofloxacin, which are usually administered 2 hours before or 6 hours after antacids.
Non-steroidal anti-inflammatory drugs (but not aspirin)
These drugs in combination with very high doses of quinolones have been shown to provoke convulsions in pre-clinical studies.
The rate and extent of absorption of ciprofloxacin was bioequivalent when Proquin XR was given alone or when Proquin XR was given 2 hours after omeprazole at the dose that maximally suppresses gastric acid secretion. Omeprazole should be taken as directed and Proquin XR should be taken with a main meal of the day, preferably the evening meal..
Altered serum levels of phenytoin (increased and decreased) have been reported in patients receiving concomitant ciprofloxacin.
Probenecid interferes with renal tubular secretion of ciprofloxacin and produces an increase in the level of ciprofloxacin in serum.
As with some other quinolones, concurrent administration of ciprofloxacin with theophylline may lead to elevated serum concentrations of theophylline and prolongation of its elimination half-life. This may result in increased risk of theophylline-related adverse reactions. If concomitant use cannot be avoided, serum levels of theophylline should be monitored and dosage adjustments made as appropriate.
Quinolones have been reported to enhance the effects of the oral anticoagulant warfarin or its derivatives. When these products are administered concomitantly, prothrombin time or other suitable coagulation tests should be monitored.

5 consumers reported dosesWhat doses of Ciprofloxacin drug you have used?
The drug can be in various doses. Most anti-diabetic, anti-hypertensive drugs, pain killers, or antibiotics are in different low and high doses and prescribed by the doctors depending on the severity and demand of the condition suffered by the patient. In our reports, ndrugs.com website users used these doses of Ciprofloxacin drug in following percentages. Very few drugs come in a fixed dose or a single dose. Common conditions, like fever, have almost the same doses, e.g., [acetaminophen, 500mg] of drug used by the patient, even though it is available in various doses.
