ADVERSE REACTIONS
Clinical efficacy trials enrolled over 9,200 moxifloxacin orally and intravenously treated patients, of whom over 8,600 patients received the 400 mg dose. Most adverse events reported in moxifloxacin trials were described as mild to moderate in severity and required no treatment. Moxifloxacin was discontinued due to adverse reactions thought to be drug-related in 2.9% of orally treated patients and 6.3 % of sequentially (intravenous followed by oral) treated patients. The latter studies were conducted in community acquired pneumonia and complicated skin and skin structure infections and complicated intra-abdominal infections with, in general, a sicker patient population compared to the tablet studies.
Adverse reactions, judged by investigators to be at least possibly drug-related, occurring in greater than or equal to 2% of moxifloxacin treated patients were: nausea (6%), diarrhea (5%), dizziness (2%).
Additional clinically relevant uncommon events, judged by investigators to be at least possibly drug-related, that occurred in greater than or equal to 0.1% and less than 2% of moxifloxacin treated patients were:
BODY AS A WHOLE: abdominal pain, headache, asthenia, dehydration (secondary to diarrhea or reduced fluid intake), injection site reaction (including phlebitis), malaise, moniliasis, pain, allergic reaction
CARDIOVASCULAR: cardiac arrhythmia (not otherwise specified), tachycardia, palpitation, vasodilation, QT interval prolonged
DIGESTIVE: vomiting, abnormal liver function test (increased transaminases, increased bilirubin), dyspepsia, dry mouth, flatulence, oral moniliasis, constipation, GGTP increased, anorexia, stomatitis, glossitis
HEMIC AND LYMPHATIC: leukopenia, eosinophilia, prothrombin decrease (prothrombin time prolonged/International Normalized Ratio (INR) increased), thrombocythemia
METABOLIC AND NUTRITIONAL: lactic dehydrogenase increased, amylase increased
MUSCULOSKELETAL: arthralgia, myalgia
NERVOUS SYSTEM: insomnia, nervousness, vertigo, somnolence, anxiety, tremor
SKIN/APPENDAGES: rash (maculopapular, purpuric, pustular), pruritus, sweating, urticaria
SPECIAL SENSES: taste perversion
UROGENITAL: vaginal moniliasis, vaginitis
Additional clinically relevant rare events, judged by investigators to be at least possibly drug-related, that occurred in less than 0.1% of moxifloxacin treated patients were:
abnormal dreams, abnormal vision (visual disturbances temporally associated with CNS symptoms), agitation, amblyopia, amnesia, anemia, aphasia, arthritis, asthma, atrial fibrillation, back pain, chest pain, confusion, convulsions of various clinical manifestations (including grand mal convulsions), depersonalization, depression (potentially culminating in self-endangering behavior), dysphagia, dyspnea, ECG abnormal, emotional lability, face edema, gastritis, gastrointestinal disorder, hallucinations, hyperglycemia, hyperlipidemia, hypertension, hypertonia, hyperuricemia, hypesthesia, hypotension, incoordination, jaundice (predominantly cholestatic), kidney function abnormal, lab test abnormal (not specified), leg pain, paraesthesia, parosmia, pelvic pain, peripheral edema, photosensitivity/phototoxicity reactions, pseudomembranous colitis, prothrombin increase (prothrombin time decreased/International Normalized Ratio (INR) decreased), sleep disorders, speech disorders, supraventricular tachycardia, syncope, taste loss, tendon disorder, thinking abnormal, thrombocytopenia, thromboplastin decrease, tinnitus, tongue discoloration, ventricular tachycardia
Post-Marketing Adverse Event Reports:
Additional adverse events have been reported from worldwide post-marketing experience with moxifloxacin. Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These events, some of them life-threatening, include anaphylactic reaction, anaphylactic shock, angioedema (including laryngeal edema), hepatic failure, including fatal cases, hepatitis (predominantly cholestatic), photosensitivity/phototoxicity reaction (see PRECAUTIONS), psychotic reaction (very rarely culminating in self-endangering behavior), renal dysfunction or renal failure, Stevens-Johnson syndrome, tendon rupture, toxic epidermal necrolysis, and ventricular tachyarrhythmias (including in very rare cases cardiac arrest and torsade de pointes, and usually in patients with concurrent severe underlying proarrhythmic conditions). Cases of altered coordination and abnormal gait as well as exacerbation of myasthenia gravis have also been reported.
LABORATORY CHANGES
Changes in laboratory parameters, without regard to drug relationship, which are not listed above and which occurred in ≥ 2% of patients and at an incidence greater than in controls included: increases in MCH, neutrophils, WBCs, PT ratio, ionized calcium, chloride, albumin, globulin, bilirubin; decreases in hemoglobin, RBCs, neutrophils, eosinophils, basophils, PT ratio, glucose, pO2, bilirubin and amylase. It cannot be determined if any of the above laboratory abnormalities were caused by the drug or the underlying condition being treated.
