1.4Infectious Diarrhea
Ciprofloxacin is indicated in adult patients for treatment of infectious diarrhea caused by Escherichia coli (enterotoxigenic isolates), Campylobacter jejuni, Shigella boydii † , Shigella dysenteriae, Shigella flexneri or Shigella sonnei † when antibacterial therapy is indicated. † Although treatment of infections due to this organism in this organ system demonstrated a clinically significant outcome, efficacy was studied in fewer than 10 patients.
Ciprofloxacin is indicated in adult patients for treatment of typhoid fever (enteric fever ) caused by Salmonella typhi. The efficacy of ciprofloxacin in the eradication of the chronic typhoid carrier state has not been demonstrated.
1.6Uncomplicated Cervical and Urethral Gonorrhea
Ciprofloxacin is indicated in adult patients for treatment of uncomplicated cervical and urethral gonorrhea due to Neisseria gonorrhoeae [see Warnings and Precautions ( 5.16 )].
1.7Inhalational Anthrax (Post-Exposure)
Ciprofloxacin is indicated in adults and pediatric patients from birth to 17 years of age for inhalational anthrax (post-exposure) to reduce the incidence or progression of disease following exposure to aerosolized Bacillus anthracis. Ciprofloxacin serum concentrations achieved in humans served as a surrogate endpoint reasonably likely to predict clinical benefit and provided the initial basis for approval of this indication. 1 Supportive clinical information for ciprofloxacin for anthrax post-exposure prophylaxis was obtained during the anthrax bioterror attacks of October 2001 [see Clinical Studies ( 14.2 )].
1.8Plague
Ciprofloxacin is indicated for treatment of plague, including pneumonic and septicemic plague, due to Yersinia pestis (Y. pestis) and prophylaxis for plague in adults and pediatric patients from birth to 17 years of age. Efficacy studies of Ciprofloxacin could not be conducted in humans with plague for feasibility reasons. Therefore this indication is based on an efficacy study conducted in animals only [see Clinical Studies ( 14.3 )] .
1.9Chronic Bacterial Prostatitis
Ciprofloxacin is indicated in adult patients for treatment of chronic bacterial prostatitis caused by Escherichia coli or Proteus mirabilis.
1.10Lower Respiratory Tract Infections
Ciprofloxacin is indicated in adult patients for treatment of lower respiratory tract infections caused by Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, Proteus mirabilis, Pseudomonas aeruginosa, Haemophilus influenzae, Haemophilus parainfluenzae, or Streptococcus pneumoniae. Ciprofloxacin is not a drug of first choice in the treatment of presumed or confirmed pneumonia secondary to Streptococcus pneumoniae.
Ciprofloxacin is indicated for the treatment of acute exacerbations of chronic bronchitis (AECB) caused by Moraxella catarrhalis. Because fluoroquinolones, including Ciprofloxacin, have been associated with serious adverse reactions [see Warnings and Precautions ( 5.1 – 5.15 )] and for some patients AECB is self-limiting, reserve Ciprofloxacin for treatment of AECB in patients who have no alternative treatment options.

Acute Uncomplicated Cystitis Ciprofloxacin is indicated in adult female patients for treatment of acute uncomplicated cystitis caused by Escherichia coli or Staphylococcus saprophyticus. Because fluoroquinolones, including Ciprofloxacin, have been associated with serious adverse reactions [see Warnings and Precautions ( 5.1 - 5.15 )] and for some patients acute uncomplicated cystitis is self-limiting, reserve Ciprofloxacin for treatment of acute uncomplicated cystitis in patients who have no alternative treatment options.
Complicated Urinary Tract Infection and Pyelonephritis in Pediatric Patients Ciprofloxacin is indicated in pediatric patients aged one to 17 years of age for treatment of complicated urinary tract infections (cUTI) and pyelonephritis due to Escherichia coli [see Use in Specific Populations ( 8.4 )] . Although effective in clinical trials, Ciprofloxacin is not a drug of first choice in the pediatric population due to an increased incidence of adverse reactions compared to controls, including reactions related to joints and/or surrounding tissues.
Ciprofloxacin, like other fluoroquinolones, is associated with arthropathy and histopathological changes in weight-bearing joints of juvenile animals [see Warnings and Precautions ( 5.12 ), Adverse Reactions ( 6.1 ), Use in Specific Populations ( 8.4 ) and Nonclinical Toxicology ( 13.2 )].
1.12Acute Sinusitis
Ciprofloxacin is indicated in adult patients for treatment of acute sinusitis caused by or Ciprofloxacin is indicated in adult patients for treatment of acute sinusitis caused by Haemophilus influenzae, Streptococcus pneumoniae, or Moraxella catarrhalis. Because fluoroquinolones, including Ciprofloxacin, have been associated with serious adverse reactions and for some patients acute sinusitis is self-limiting, reserve Ciprofloxacin for treatment of acute sinusitis in patients who have no alternative treatment options.
Because fluoroquinolones, including Ciprofloxacin, have been associated with serious adverse reactions [see Warnings and Precautions ( 5.1 - 5.15 )] and for some patients acute sinusitis is self-limiting, reserve Ciprofloxacin for treatment of acute sinusitis in patien

Contraindications
Known hypersensitivity to Ciprofloxacin or other quinolones ( 4.1 , 5.6 , 5.7 ) Concomitant administration with tizanidine ( 4.2 )
4.1Hypersensitivity
Ciprofloxacin is contraindicated in persons with a history of hypersensitivity to ciprofloxacin, any member of the quinolone class of antibacterials, or any of the product components [see Warnings and Precautions ( 5.7 )].
4.2Tizanidine
Concomitant administration with tizanidine is contraindicated [see Drug Interactions ( 7 )].
Warnings and precautions
Hypersensitivity and other serious reactions: Serious and sometimes fatal reactions (for example, anaphylactic reactions) may occur after the first or subsequent doses of Ciprofloxacin. Discontinue Ciprofloxacin at the first sign of skin rash, jaundice or any sign of hypersensitivity. ( 4.1 , 5.6 , 5.7 ) Hepatotoxicity: Discontinue immediately if signs and symptoms of hepatitis occur. ( 5.8 ) Clostridium difficile -associated diarrhea: Evaluate if colitis occurs.
( 5.10 ) QT Prolongation: Prolongation of the QT interval and isolated cases of torsade de pointes have been reported. Avoid use in patients with known prolongation, those with hypokalemia, and with other drugs that prolong the QT interval. ( 5.11 , 7 , 8.5 )
5.1 Disabling and Potentially Irreversible Serious Adverse Reactions Including Tendinitis and Tendon Rupture, Peripheral Neuropathy, and Central Nervous System Effects Fluoroquinolones, including Ciprofloxacin, have been associated with disabling and potentially irreversible serious adverse reactions from different body systems that can occur together in the same patient. Commonly seen adverse reactions include tendinitis, tendon rupture, arthralgia, myalgia, peripheral neuropathy, and central nervous system effects (hallucinations, anxiety, depression, insomnia, severe headaches, and confusion).
These reactions can occur within hours to weeks after starting Ciprofloxacin. Patients of any age or without pre-existing risk factors have experienced these adverse reactions [see Warnings and Precautions ( 5.2 , 5.3 , 5.4 )] . Discontinue Ciprofloxacin immediately at the first signs or symptoms of any serious adverse reaction. In addition, avoid the use of fluoroquinolones, including Ciprofloxacin, in patients who have experienced any of these serious adverse reactions associated with fluoroquinolones.
5.2Tendinitis and Tendon Rupture
Fluoroquinolones, including Ciprofloxacin, have been associated with an increased risk of tendinitis and tendon rupture in all ages [see Warnings and Precautions ( 5.1 ) and Adverse Reactions ( 6.2 )] . This adverse reaction most frequently involves the Achilles tendon, and has also been reported with the rotator cuff (the shoulder), the hand, the biceps, the thumb, and other tendons. Tendinitis or tendon rupture can occur, within hours or days of starting Ciprofloxacin, or as long as several months after completion of fluoroquinolone therapy.
Tendinitis and tendon rupture can occur bilaterally. The risk of developing fluoroquinolone-associated tendinitis and tendon rupture is increased in patients over 60 years of age, in patients taking corticosteroid drugs, and in patients with kidney, heart or lung transplants. Other factors that may independently increase the risk of tendon rupture include strenuous physical activity, renal failure, and previous tendon disorders such as rheumatoid arthritis.
Tendinitis and tendon rupture have also occurred in patients taking fluoroquinolones who do not have the above risk factors. Discontinue Ciprofloxacin immediately if the patient experiences pain, swelling, inflammation or rupture of a tendon. Avoid fluoroquinolones, including Ciprofloxacin, in patients who have a history of tendon disorders or have experienced tendinitis or tendon rupture [see Adverse Reactions ( 6.2 )].
5.3Peripheral Neuropathy
Fluoroquinolones, including Ciprofloxacin, have been associated with an increased risk of peripheral neuropathy. Cases of sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paresthesias, hypoesthesias, dysesthesias and weakness have been reported in patients receiving fluoroquinolones, including Ciprofloxacin. Symptoms may occur soon after initiation of Ciprofloxacin and may be irreversible in some patients [see Warnings and Precautions ( 5.1 ) and Adverse Reactions ( 6.1 , 6.2 )] .
Discontinue Ciprofloxacin immediately if the patient experiences symptoms of peripheral neuropathy including pain, burning, tingling, numbness, and/or weakness, or other alterations in sensations including light touch, pain, temperature, position sense and vibratory sensation, and/or motor strength in order to minimize the development of an irreversible condition. Avoid fluoroquinolones, including Ciprofloxacin, in patients who have previously experienced peripheral neuropathy [see Adverse Reactions ( 6.1 , 6.2 )].
5.4Central Nervous System Effects
Fluoroquinolones, including Ciprofloxacin, have been associated with an increased risk of central nervous system (CNS) effects, including. convulsions, increased intracranial pressure (including pseudotumor cerebri), and toxic psychosis. Ciprofloxacin may also cause central nervous system (CNS) events including: nervousness, agitation, insomnia, anxiety, nightmares, paranoia, dizziness, confusion, tremors, hallucinations, depression, and psychotic reactions have progressed to suicidal ideations/thoughts and self-injurious behavior such as attempted or completed suicide.
These reactions may occur following the first dose. Advise patients receiving Ciprofloxacin to inform their healthcare provider immediately if these reactions occur, discontinue the drug, and institute appropriate care. Ciprofloxacin, like other fluoroquinolones, is known to trigger seizures or lower the seizure threshold. As with all fluoroquinolones, use Ciprofloxacin with caution in epileptic patients and patients with known or suspected CNS disorders that may predispose to seizures or lower the seizure threshold (for example, severe cerebral arteriosclerosis, previous history of convulsion, reduced cerebral blood flow, altered brain structure, or stroke), or in the presence of other risk factors that may predispose to seizures or lower the seizure threshold (for example, certain drug therapy, renal dysfunction).
Use Ciprofloxacin when the benefits of treatment exceed the risks, since these patients are endangered because of possible undesirable CNS side effects. Cases of status epilepticus have been reported. If seizures occur, discontinue Ciprofloxacin [see Adverse Reactions ( 6.1 ) and Drug Interactions ( 7 )].
5.5Exacerbation of Myasthenia Gravis
Fluoroquinolones, including Ciprofloxacin, have neuromuscular blocking activity and may exacerbate muscle weakness in patients with myasthenia gravis. Postmarketing serious adverse reactions, including deaths and requirement for ventilatory support, have been associated with fluoroquinolone use in patients with myasthenia gravis. Avoid Ciprofloxacin in patients with known history of myasthenia gravis [see Adverse Reactions ( 6.2 )].
5.6Other Serious and Sometimes Fatal Adverse Reactions
Other serious and sometimes fatal adverse reactions, some due to hypersensitivity, and some due to uncertain etiology, have been reported in patients receiving therapy with quinolones, including Ciprofloxacin. These events may be severe and generally occur following the administration of multiple doses. Clinical manifestations may include one or more of the following: Fever, rash, or severe dermatologic reactions (for example, toxic epidermal necrolysis, Stevens Johnson syndrome); Vasculitis; arthralgia; myalgia; serum sickness; Allergic pneumonitis; Interstitial nephritis; acute renal insufficiency or failure; Hepatitis; jaundice; acute hepatic necrosis or failure; Anemia, including hemolytic and aplastic; thrombocytopenia, including thrombotic thrombocytopenic purpura; leukopenia; agranulocytosis; pancytopenia; and/or other hematologic abnormalities.
Discontinue Ciprofloxacin immediately at the first appearance of a skin rash, jaundice, or any other sign of hypersensitivity and supportive measures instituted [see Adverse Reactions ( 6.1 , 6.2 )].
5.7Hypersensitivity Reactions Serious
and occasionally fatal hypersensitivity (anaphylactic) reactions, some following the first dose, have been reported in patients receiving fluoroquinolone therapy, including Ciprofloxacin. Some reactio

Interactions
Ciprofloxacin is an inhibitor of human cytochrome P450 1A2 (CYP1A2) mediated metabolism. Co-administration of Ciprofloxacin with other drugs primarily metabolized by CYP1A2 results in increased plasma concentrations of these drugs and could lead to clinically significant adverse events of the co-administered drug. Table 9: Drugs That are Affected by and Affecting Ciprofloxacin Drugs That are Affected by Ciprofloxacin Drug(s) Recommendation Comments Tizanidine Contraindicated Concomitant administration of tizanidine and Ciprofloxacin is contraindicated due to the potentiation of hypotensive and sedative effects of tizanidine [ see Contraindications ( 4.2 ) ] Theophylline Avoid Use (Plasma Exposure Likely to be Increased and Prolonged) Concurrent administration of Ciprofloxacin with theophylline may result in increased risk of a patient developing central nervous system (CNS) or other adverse reactions.
If concomitant use cannot be avoided, monitor serum levels of theophylline and adjust dosage as appropriate [see Warnings and Precautions ( 5.9 )]. Drugs Known to Prolong QT Interval Avoid Use Ciprofloxacin may further prolong the QT interval in patients receiving drugs known to prolong the QT interval (for example, class IA or III antiarrhythmics, tricyclic antidepressants, macrolides, antipsychotics) [see Warnings and Precautions ( 5.11 ) and Use in Specific Populations ( 8.5 )].
Oral antidiabetic drugs Use with caution Glucose-lowering effect potentiated Hypoglycemia sometimes severe has been reported when Ciprofloxacin and oral antidiabetic agents, mainly sulfonylureas (for example, glyburide, glimepiride), were co-administered, presumably by intensifying the action of the oral antidiabetic agent. Fatalities have been reported. Monitor blood glucose when Ciprofloxacin is co-administered with oral antidiabetic drugs [see Adverse Reactions ( 6.1 )].
Phenytoin Use with caution Altered serum levels of phenytoin (increased and decreased) To avoid the loss of seizure control associated with decreased phenytoin levels and to prevent phenytoin overdose-related adverse reactions upon Ciprofloxacin discontinuation in patients receiving both agents, monitor phenytoin therapy, including phenytoin serum concentration during and shortly after co-administration of Ciprofloxacin with phenytoin.
Cyclosporine Use with caution (transient elevations in serum creatinine) Monitor renal function (in particular serum creatinine) when Ciprofloxacin is co-administered with cyclosporine. Anti-coagulant drugs Use with caution (Increase in anticoagulant effect) The risk may vary with the underlying infection, age and general status of the patient so that the contribution of Ciprofloxacin to the increase in INR (international normalized ratio) is difficult to assess.
Monitor prothrombin time and INR frequently during and shortly after co-administration of Ciprofloxacin with an oral anti-coagulant (for example, warfarin). Methotrexate Use with caution Inhibition of methotrexate renal tubular transport potentially leading to increased methotrexate plasma levels Potential increase in the risk of methotrexate associated toxic reactions. Therefore, carefully monitor patients under methotrexate therapy when concomitant Ciprofloxacin therapy is indicated.
Ropinirole Use with caution Monitoring for ropinirole-related adverse reactions and appropriate dose adjustment of ropinirole is recommended during and shortly after co-administration with Ciprofloxacin [see Warnings and Precautions ( 5.16 )]. Clozapine Use with caution Careful monitoring of clozapine associated adverse reactions and appropriate adjustment of clozapine dosage during and shortly after co-administration with Ciprofloxacin are advised.
NSAIDs Use with caution Non-steroidal anti-inflammatory drugs (but not acetyl salicylic acid) in combination of very high doses of quinolones have been shown to provoke convulsions in pre-clinical studies and in postmarketing. Sildenafil Use with caution Two-fold increase in exposure Monitor for sildenafil toxicity [see Clinical Pharmacology ( 12.3 ) ] . Duloxetine Avoid Use If unavoidable, monitor for duloxetine toxicity Five-fold increase in duloxetine exposure Caffeine/Xanthine Use with caution Ciprofloxacin inhibits the formation of paraxanthine after caffeine Derivatives Reduced clearance resulting in elevated levels and prolongation of serum half-life administration (or pentoxifylline containing products).
Monitor for xanthine toxicity and adjust dose as necessary. Drug(s) Affecting Pharmacokinetics of Ciprofloxacin Antacids, Sucralfate, Multivitamins and Other Products Containing Multivalent Cations (magnesium/aluminum antacids; polymeric phosphate binders (for example, sevelamer, lanthanum carbonate); sucralfate; Videx ® (didanosine) chewable/buffered tablets or pediatric powder; other highly buffered drugs; or products containing calcium, iron, or zinc and dairy products) Ciprofloxacin should be taken at least two hours before or six hours after Multivalent cation-containing products administration [see Dosage and Administration ( 2.4 )].
Decrease Ciprofloxacin absorption, resulting in lower serum and urine levels Probenecid Use with caution (interferes with renal tubular secretion of Ciprofloxacin and increases Ciprofloxacin serum levels) Potentiation of Ciprofloxacin toxicity may occur. Interacting Drug Interaction Theophylline Serious and fatal reactions. Avoid concomitant use. Monitor serum level ( 7 ) Warfarin Anticoagulant effect enhanced. Monitor prothrombin time, INR, and bleeding ( 7 ) Antidiabetic agents Hypoglycemia including fatal outcomes have been reported.
Monitor blood glucose ( 7 ) Phenytoin Monitor phenytoin level ( 7 ) Methotrexate Monitor for methotrexate toxicity ( 7 ) Cyclosporine May increase serum creatinine. Monitor serum creatinine ( 7 ) Multivalent cation-containing products including antacids, metal cations or didanosine Decreased Ciprofloxacin absorption. Take 2 hours before or 6 hours after Ciprofloxacin ( 7 )
Pregnancy and breastfeeding
8.1Pregnancy Pregnancy Category C
There are no adequate and well-controlled studies in pregnant women. Ciprofloxacin should not be used during pregnancy unless the potential benefit justifies the potential risk to both fetus and mother. An expert review of published data on experiences with ciprofloxacin use during pregnancy by TERIS–the Teratogen Information System–concluded that therapeutic doses during pregnancy are unlikely to pose a substantial teratogenic risk (quantity and quality of data=fair), but the data are insufficient to state that there is no risk. 2 A controlled prospective observational study followed 200 women exposed to fluoroquinolones (52.5% exposed to ciprofloxacin and 68% first trimester exposures) during gestation. 3 In utero exposure to fluoroquinolones during embryogenesis was not associated with increased risk of major malformations.
The reported rates of major congenital malformations were 2.2% for the fluoroquinolone group and 2.6% for the control group (background incidence of major malformations is 1–5%). Rates of spontaneous abortions, prematurity and low birth weight did not differ between the groups and there were no clinically significant musculoskeletal dysfunctions up to one year of age in the ciprofloxacin exposed children. Another prospective follow-up study reported on 549 pregnancies with fluoroquinolone exposure (93% first trimester exposures). 4 There were 70 ciprofloxacin exposures, all within the first trimester.
The malformation rates among live-born babies exposed to ciprofloxacin and to fluoroquinolones overall were both within background incidence ranges. No specific patterns of congenital abnormalities were found. The study did not reveal any clear adverse reactions due to in utero exposure to ciprofloxacin. No differences in the rates of prematurity, spontaneous abortions, or birth weight were seen in women exposed to ciprofloxacin during pregnancy. 2, 3 However, these small postmarketing epidemiology studies, of which most experience is from short term, first trimester exposure, are insufficient to evaluate the risk for less common defects or to permit reliable and definitive conclusions regarding the safety of ciprofloxacin in pregnant women and their developing fetuses.
Reproduction studies have been performed in rats and mice using oral doses up to 100 mg/kg (0.6 and 0.3 times the maximum daily human dose based upon body surface area, respectively) and have revealed no evidence of harm to the fetus due to ciprofloxacin. In rabbits, oral ciprofloxacin dose levels of 30 and 100 mg/kg (approximately 0.4- and 1.3-times the highest recommended therapeutic dose based upon body surface area) produced gastrointestinal toxicity resulting in maternal weight loss and an increased incidence of abortion, but no teratogenicity was observed at either dose level.
After intravenous administration of doses up to 20 mg/kg (approximately 0.3-times the highest recommended therapeutic dose based upon body surface area), no maternal toxicity was produced and no embryo toxicity or teratogenicity was observed.

6.1Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adult Patients During clinical investigations with oral and parenteral Ciprofloxacin, 49,038 patients received courses of the drug. The most frequently reported adverse reactions, from clinical trials of all formulations, all dosages, all drug-therapy durations, and for all indications of ciprofloxacin therapy were nausea (2.5%), diarrhea (1.6%), liver function tests abnormal (1.3%), vomiting (1%), and rash (1%).

Pediatric Patients Short (6 weeks) and long term (1 year) musculoskeletal and neurological safety of oral/intravenous ciprofloxacin, was compared to a cephalosporin for treatment of cUTI or pyelonephritis in pediatric patients 1 to 17 years of age (mean age of 6 ± 4 years) in an international multicenter trial. The duration of therapy was 10 to 21 days (mean duration of treatment was 11 days with a range of 1 to 88 days).
A total of 335 ciprofloxacin- and 349 comparator-treated patients were enrolled. An Independent Pediatric Safety Committee (IPSC) reviewed all cases of musculoskeletal adverse reactions including abnormal gait or abnormal joint exam (baseline or treatment-emergent). Within 6 weeks of treatment initiation, the rates of musculoskeletal adverse reactions were 9.3% (31/335) in the ciprofloxacin-treated group versus 6% (21/349) in comparator-treated patients.
All musculoskeletal adverse reactions occurring by 6 weeks resolved (clinical resolution of signs and symptoms), usually within 30 days of end of treatment. Radiological evaluations were not routinely used to confirm resolution of the adverse reactions. Ciprofloxacin-treated patients were more likely to report more than one adverse reaction and on more than one occasion compared to control patients. The rate of musculoskeletal adverse reactions was consistently higher in the ciprofloxacin group compared to the control group across all age subgroups.
At the end of 1 year, the rate of these adverse reactions reported at any time during that period was 13.7% (46/335) in the ciprofloxacin-treated group versus 9.5% (33/349) in the comparator-treated patients ( Table 7 ). Table 7: Musculoskeletal Adverse Reactions 1 as Assessed by the IPSC 1. Included: arthralgia, abnormal gait, abnormal joint exam, joint sprains, leg pain, back pain, arthrosis, bone pain, pain, myalgia, arm pain, and decreased range of motion in a joint (knee, elbow, ankle, hip, wrist, and shoulder) 2.
The study was designed to demonstrate that the arthropathy rate for the Ciprofloxacin group did not exceed that of the control group by more than + 6%. At both the 6 week and 1 year evaluations, the 95% confidence interval indicated that it could not be concluded that the Ciprofloxacin group had findings comparable to the control group. Ciprofloxacin Comparator All Patients (within 6 weeks) 31/335 (9.3%) 21/349 (6%) 95% Confidence Interval 2 (-0.8%, +7.2%) Age Group 12 months < 24 months 1/36 (2.8%) 0/41 2 years < 6 years 5/124 (4%) 3/118 (2.5%) 6 years < 12 years 18/143 (12.6%) 12/153 (7.8%) 12 years to 17 years 7/32 (21.9%) 6/37 (16.2 %) All Patients (within 1 year) 46/335 (13.7%) 33/349 (9.5%) 95% Confidence Interval 1 (-0.6%, + 9.1%) The incidence rates of neurological adverse reactions within 6 weeks of treatment initiation were 3% (9/335) in the Ciprofloxacin group versus 2% (7/349) in the comparator group and included dizziness, nervousness, insomnia, and somnolence.
In this trial, the overall incidence rates of adverse reactions within 6 weeks of treatment initiation were 41% (138/335) in the ciprofloxacin group versus 31% (109/349) in the comparator group. The most frequent adverse reactions were gastrointestinal: 15% (50/335) of ciprofloxacin patients compared to 9% (31/349) of comparator patients. Serious adverse reactions were seen in 7.5% (25/335) of ciprofloxacin treated patients compared to 5.7% (20/349) of control patients.
Discontinuation of drug due to an adverse reaction was observed in 3% (10/335) of ciprofloxacin-treated patients versus 1.4% (5/349) of comparator patients. Other adverse reactions that occurred in at least 1% of ciprofloxacin patients were diarrhea 4.8%, vomiting 4.8%, abdominal pain 3.3%, dyspepsia 2.7%, nausea 2.7%, fever 2.1%, asthma 1.8% and rash 1.8%.
