SERIOUS ADVERSE REACTIONS INCLUDING TENDINITIS, TENDON RUPTURE, PERIPHERAL NEUROPATHY, CENTRAL NERVOUS SYSTEM EFFECTS AND EXACERBATION OF MYASTHENIA GRAVIS Fluoroquinolones, including moxifloxacin hydrochloride, have been associated with disabling and potentially irreversible serious adverse reactions that have occurred together [see Warnings and Precautions (5.1) ] , including: Tendinitis and tendon rupture [see Warnings and Precautions (5.2) ] Peripheral neuropathy [see Warnings and Precautions (5.3) ] Central nervous system effects [see Warnings and Precautions (5.4) ] Discontinue moxifloxacin hydrochloride immediately and avoid the use of fluoroquinolones, including moxifloxacin hydrochloride, in patients who experience any of these serious adverse reactions [see Warnings and Precautions (5.1) ]. Fluoroquinolones, including moxifloxacin hydrochloride, may exacerbate muscle weakness in patients with myasthenia gravis. Avoid moxifloxacin hydrochloride in patients with known history of myasthenia gravis [see Warnings and Precautions (5.5) ].

Warnings & precautions
Sourced from openFDAProlongation of the QT interval and isolated cases of torsade de pointes has been reported. Avoid use in patients with known prolongation, proarrhythmic conditions such as clinically significant bradycardia or acute myocardial ischemia, hypokalemia, hypomagnesemia, and with drugs that prolong the QT interval. ( 5.6 , 7.5 , 8.5 ) Hypersensitivity and other serious reactions: Serious and sometimes fatal reactions, including anaphylactic reactions, may occur after first or subsequent doses of moxifloxacin hydrochloride. Discontinue moxifloxacin hydrochloride at first sign of skin rash, jaundice or any other sign of hypersensitivity. ( 5.7 , 5.8 ) Clostridioides difficile -Associated Diarrhea: Evaluate if diarrhea occurs. ( 5.10 ) 5.1 Disabling and Potentially Irreversible Serious Adverse Reactions Including Tendinitis and Tendon Rupture, Peripheral Neuropathy, and Central Nervous System Effects Fluoroquinolones, including moxifloxacin hydrochloride, 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 moxifloxacin hydrochloride. 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) ] .
Adverse reactions
Sourced from openFDAThe following serious and otherwise important adverse reactions are discussed in greater detail in the warnings and precautions section of the label: Disabling and Potentially Irreversible Serious Adverse Reactions Including Tendinitis and Tendon Rupture, Peripheral Neuropathy, and Central Nervous System Effects [see Warnings and Precautions (5.1) ] Tendinitis and Tendon Rupture [see Warnings and Precautions (5.2) ] Peripheral Neuropathy [see Warnings and Precautions (5.3) ] Central Nervous System Effects [see Warnings and Precautions (5.4) ] Exacerbation of Myasthenia Gravis [see Warnings and Precautions (5.5) ] QT Prolongation [see Warnings and Precautions (5.6) ] Other Serious and Sometimes Fatal Adverse Reactions [see Warnings and Precautions (5.7) ] Risk of Aortic Aneurysm and Dissection [see Warnings and Precautions (5.9) ] Hypersensitivity Reactions [see Warnings and Precautions (5.8) ] Clostridioides difficile -Associated Diarrhea [see Warnings and Precautions (5.10) ] Blood Glucose Disturbances [see Warnings and Precautions (5.12) ] Photosensitivity/Phototoxicity [see Warnings and Precautions (5.13) ] Development of Drug Resistant Bacteria [see Warnings and Precautions (5.14) ] Most common reactions (3% or greater) were nausea, diarrhea, headache, and dizziness.

Use in specific populations
Sourced from openFDAPregnancy: Based on animal data may cause fetal harm. (8.1) Geriatrics: Increased risk for severe tendon disorders further increased by concomitant corticosteroid therapy and increased risk of prolongation of the QT interval. (5.1 , 5.6 , 8.5) 8.1 Pregnancy Risk Summary There are no available human data establishing a drug associated risk with the use of moxifloxacin. Based on animal studies with moxifloxacin, moxifloxacin hydrochloride may cause fetal harm. Moxifloxacin did not cause fetal malformations when administered to pregnant rats (IV and oral), rabbits (IV), and monkeys (oral) at exposures that were 0.24 to 2.5 times of those at the human clinical dose (400 mg/day moxifloxacin hydrochloride). However, when moxifloxacin was administered to rats and rabbits during pregnancy and throughout lactation (rats only) at doses associated with maternal toxicity, decreased neonatal body weights, increased incidence of skeletal variations (rib and vertebra combined), and increased fetal loss were observed (see Data). Advise pregnant women of the potential risk to the fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S.
Pharmacokinetics
Sourced from openFDA- Metabolism
- Absorption Moxifloxacin, given as an oral tablet, is well absorbed from the gastrointestinal tract. The absolute bioavailability of moxifloxacin is approximately 90 percent.
Overdosage
Sourced from openFDASingle oral overdoses up to 2.8 g were not associated with any serious adverse events. In the event of acute overdose, empty the stomach and maintain adequate hydration. Monitor ECG due to the possibility of QT interval prolongation. Carefully observe the patient and give supportive treatment. The administration of activated charcoal as soon as possible after oral overdose may prevent excessive increase of systemic moxifloxacin exposure. About 3% and 9% of the dose of moxifloxacin, as well as about 2% and 4.5% of its glucuronide metabolite are removed by continuous ambulatory peritoneal dialysis and hemodialysis, respectively.
