Moxifloxacin has been generally well tolerated with most adverse events reported as mild to moderate and requiring no treatment. Moxifloxacin was discontinued due to adverse reactions in 5% of patients overall, 4.1% of patients received 400 mg orally, 3.9% received 400 mg intravenously, and 8.2% received 400 mg intravenous/oral sequential treatment. The most common side effects leading to discontinuation with the oral dose were nausea (0.8%), diarrhea (0.5%), dizziness (0.5%), and vomiting (0.4%). The most common side effect leading to discontinuation with the intravenous dose was rash (0.5%). The most common side effects leading to discontinuation with the intravenous/oral sequential dose were diarrhea (0.5%) and pyrexia (0.4%).
Gastrointestinal side effects have included nausea (6.9%), diarrhea (6%), vomiting (2.4%), constipation (1.9%), abdominal pain (1.5%), upper abdominal pain (1.1%), and dyspepsia (1%). Dry mouth, abdominal discomfort, abdominal distention, gastritis, gastroesophageal reflux disease, oral candidiasis, oral fungal infection, gastroenteritis, anorexia, and flatulence have been reported in 0.1% to less than 1% of patients. Clostridium difficile associated diarrhea, dysphagia, gastrointestinal disorder, pseudomembranous colitis, stomatitis, glossitis, and tongue discoloration have been reported.
The onset of pseudomembranous colitis symptoms may occur during or after antimicrobial treatment. If diarrhea occurs and it is unresponsive to discontinuation of drug and/or standard therapy, pseudomembranous colitis should be considered.
Nervous system side effects have included headache (4.2%), dizziness (3%), and insomnia (1.9%). Somnolence, tremor, dysgeusia, lethargy, paresthesia, tension headache, hallucinations, hypoesthesia, syncope, tinnitus, and vertigo have been reported in 0.1% to less than 1% of patients. Amnesia, aphasia, confusion, convulsions of various clinical manifestations (including grand mal convulsions), incoordination, parosmia, sleep disorders, speech disorders, and abnormal thinking have been reported. Altered coordination, abnormal gait, and exacerbation of myasthenia gravis have been reported during postmarketing experience. Quinolones have been associated with sensory and sensorimotor axonal polyneuropathy resulting in paresthesias, hypoesthesias, dysesthesias, and weakness.
Cardiovascular side effects have included atrial fibrillation, palpitations, tachycardia, congestive cardiac failure, angina pectoris, cardiac failure, cardiac arrest, bradycardia, hypertension, hypotension, phlebitis, increased blood pressure, and prolonged electrocardiogram QT interval in 0.1% to less than 1% of patients. Abnormal ECG, arrhythmias, atrial flutter, ST-T wave changes, supraventricular tachycardia, cardiac arrhythmia (not otherwise specified), vasodilation, ventricular extrasystoles, and ventricular tachycardia have been reported. Elderly patients experienced more ECG abnormalities than younger patients. Ventricular tachyarrhythmias (including in very rare cases cardiac arrest and torsade de pointes, and usually in patients with concurrent severe underlying proarrhythmic conditions) have been reported during postmarketing experience.
The mean QTc interval prolongation in a study of 787 patients receiving moxifloxacin was 6 msec vs. 1 msec for a comparator group of patients receiving another antibiotic. There were 38 outliers in the moxifloxacin group (QTc interval greater than 450 msec for men or 470 msec for women) vs. 28 outliers in the comparator group.
In another study (n=48), there were greater increases in the QT and QTc interval with 800 mg moxifloxacin than with 1000 mg levofloxacin or 1500 mg ciprofloxacin.
Hematologic side effects have included anemia (1.1%). Prolonged prothrombin time, thrombocythemia, eosinophilia, neutropenia, thrombocytopenia, leukocytosis, leukopenia, increased platelet count, decreased hemoglobin, increased white blood cell count, decreased hematocrit, increased eosinophil count, and prolonged activated partial thromboplastin time have been reported in 0.1% to less than 1% of patients. Increased MCH, neutrophils, WBCs, albumin, and PT ratio, and decreased hemoglobin, RBCs, neutrophils, eosinophils, basophils, and PT ratio have been reported in greater than or equal to 2% of patients; however, it has not been determined if these laboratory abnormalities were due to the drug or the underlying condition being treated. Increased prothrombin (decreased prothrombin time, decreased INR), decreased thromboplastin, and decreased prothrombin (increased INR) have been reported. Agranulocytosis and pancytopenia have been reported during postmarketing experience.
Hepatic side effects have included increased alanine aminotransferase (1.1%). Abnormal liver function tests, abnormal hepatic function, and increased aspartate aminotransferase, transaminases, blood bilirubin, hepatic enzyme, and gamma-glutamyltransferase have been reported in 0.1% to less than 1% of patients. Increased and decreased bilirubin have been reported in greater than or equal to 2% of patients; however, it has not been determined if these laboratory abnormalities were due to the drug or the underlying condition being treated. Jaundice (primarily cholestatic) and acute fulminant hepatic failure have been reported. Hepatic failure (including fatal cases), jaundice, acute hepatic necrosis, and hepatitis (primarily cholestatic) have been reported during postmarketing experience.
A 69-year-old male developed jaundice, pruritus, weight loss, dark urine, elevated lever function tests (total bilirubin, 28.45 mg/dL; conjugated bilirubin, 20.6 mg/dL; alkaline phosphatase, 249 units/L; ALT, 58 units/L) 3 weeks after a 5-day course of oral moxifloxacin. A liver biopsy showed portal inflammatory infiltrates with lymphocytes and eosinophils and predominantly casts in canaliculi. Liver function tests normalized over 2 months.
A 23-year-old female developed acute fulminant hepatitis (transaminases up to 8500 units/L) with hepatocellular necrosis, toxic epidermal necrolysis, and encephalopathy after 3 days of moxifloxacin treatment. The condition culminated in multiple organ failure, acute respiratory distress syndrome, and death, despite a liver transplant.
