Serious and Otherwise Important Adverse Reactions
The following serious and otherwise important adverse drug reactions are discussed in greater detail in other sections of labeling:
- Tendon Effects [see WARNINGS AND PRECAUTIONS]
- Hypersensitivity Reactions [see WARNINGS AND PRECAUTIONS]
- Other Serious and Sometimes Fatal Reactions [see WARNINGS AND PRECAUTIONS]
- Central Nervous System Effects [see WARNINGS AND PRECAUTIONS]
- Clostridium difficile-Associated Diarrhea [see WARNINGS AND PRECAUTIONS]
- Peripheral Neuropathy [see WARNINGS AND PRECAUTIONS]
- Photosensitivity/Phototoxicity [see WARNINGS AND PRECAUTIONS]
- Development of Drug Resistant Bacteria [see WARNINGS AND PRECAUTIONS]
Crystalluria and cylindruria have been reported with quinolones, including ciprofloxacin. Therefore, adequate hydration of patients receiving Proquin XR (ciprofloxacin hcl) should be maintained to prevent the formation of highly concentrated urine [see DOSAGE AND ADMINISTRATION].
Clinical Trial 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.
The data described below reflect exposure to Proquin XR (ciprofloxacin hcl) in 524 patients in one clinical trial. The population studied had a mean age of 39 years (approximately 93.4% of the population were < 65 years of age), 100% were female, 77% were Caucasian and 7.4% were Black. Patients received Proquin XR (ciprofloxacin hcl) 500 mg once daily for 3 days. Patients were followed for approximately 5 weeks after the end of study drug dosing.
Discontinuation of Proquin XR (ciprofloxacin hcl) occurred in 1.4% of patients. Each of the discontinuations were for a different adverse reactions. Refer to Table 1.
The most common adverse reactions ( ≥ 2%) were fungal infection, nasopharyngitis, headache, and micturition urgency.
Table 1: Adverse reactions (regardless of relationship to study drug) occurring in ≥ 1% of Proquin XR (ciprofloxacin hcl) -treated patients (500 mg once daily for 3 days) during the entire study period compared to ciprofloxacin-immediate release tablets (250 mg twice daily for 3 days)
|Adverse Reaction||Proquin XR||Ciprofloxacin-immediate release tablets|
|Urinary tract infection||10.8||9.8|
|Upper respiratory tract infection||1.4||2.9|
The incidence of adverse events (regardless of relationship to study drug) reported for at least 1% of patients treated with Proquin XR (ciprofloxacin hcl) during study drug treatment and up to 3 days after study drug was headache (1.5%).
Less common reactions, occurring at any time during the study in less than 1% of Proquin XR (ciprofloxacin hcl) -treated patients were:
- Cardiac Disorders: ventricular bigeminy.
- Immune System Disorders: hypersensitivity.
- Gastrointestinal Disorders: abdominal pain, nausea, diarrhea, dyspepsia, aggravated irritable bowel syndrome, lower abdominal pain, vomiting.
- General Disorders: suprapubic pain, fatigue, pain, rigors, tenderness.
- Infections and Infestations: urinary tract infection, fungal vaginosis, bacterial vaginitis, vaginal candidiasis, vaginal infection, vaginitis.
- Investigations: blood bilirubin increased, alanine aminotransferase increased, abdominal aortic bruit, aspartate aminotransferase increased, body temperature increased.
- Musculoskeletal and Connective Tissue Disorders: joint swelling, muscle spasms, night cramps.
- Nervous System Disorders: headache, dizziness, disturbance in attention, paresthesia.
- Renal and Urinary Disorders: micturition urgency, dysuria, urinary frequency, abnormal urine odor, hematuria.
- Reproductive System and Breast Disorders: female genital pruritus.
- Respiratory, Thoracic, and Mediastinal Disorders: dyspnea.
- Skin/Subcutaneous Tissue Disorders: rash, photosensitivity/ phototoxicity reaction, pruritus, urticaria.
Adverse Reactions Reported with Other Systemic Formulations of Ciprofloxacin
In addition, to the adverse reactions reported with Proquin XR (ciprofloxacin hcl), the following adverse reactions have been reported during clinical trials and from worldwide post-marketing experience with other systemic formulations of ciprofloxacin (includes all dosages and indications).
Because these reactions have been reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or a causal relationship to drug exposure.
