Bacterial conjunctivitis: Ophthalmic:
Moxeza: Instill 1 drop into affected eye(s) 2 times daily for 7 days.
Vigamox: Instill 1 drop into affected eye(s) 3 times daily for 7 days.
Surgical prophylaxis (off-label use): Instill 1 drop into operative eye every 5 to 15 minutes for five doses within the hour prior to the start of the procedure (ASHP/IDSA/SIS/SHEA [Bratzler 2013]). Note: Prophylactic administration has ranged from preoperatively (including day of surgery only to 1 to 3 days preoperatively), intraoperatively, at end of procedure, and postoperatively. However, no specific recommendations beyond immediate preoperative use, including duration of prophylaxis, can be made due to insufficient evidence. A total duration (pre- and postoperatively) of up to 15 days has been reported (ASHP/IDSA/SIS/SHEA [Bratzler 2013]; Freitas 2007; Speaker 2009).
There are no dosage adjustments provided in the manufacturer's labeling. However, dosage adjustment unlikely due to low systemic absorption.

For topical ophthalmic use only; not for injection. Avoid touching tip of applicator to eye, finger, or other surfaces. Apply gentle pressure to lacrimal sac during and immediately following instillation (1 minute) or instruct patient to gently close eyelid after administration, to decrease systemic absorption of ophthalmic drops (Urtti 1993; Zimmerman 1982).

Moxeza ophthalmic solution: There are no contraindications listed in manufacturer's labeling
Vigamox: Hypersensitivity to moxifloxacin, other quinolone antibiotics, or any component of the formulation
Concerns related to adverse effects:
• Hypersensitivity reactions: Severe hypersensitivity reactions, including anaphylaxis, angioedema, and dermatologic reactions, have been reported with systemic use of moxifloxacin. Discontinue use if an allergic reaction occurs.
• Superinfection: Prolonged use may lead to overgrowth of nonsusceptible organisms, including fungi. If superinfection occurs, discontinue use and institute appropriate alternative therapy.
• Toxic anterior segment syndrome: Toxic anterior segment syndrome, which may consist of corneal edema, fibrin, cell or flare, hypopyon, keratic precipitates, or vitreous opacities, has occurred with intraocular administration.
Dosage form specific issues:
• Ophthalmic solution: For topical ophthalmic use only. Not for subconjunctival injection or for direct introduction into the anterior chamber of the eye. Contact lenses should not be worn during therapy.
None known.
There are no known significant interactions.
When administered orally or IV, moxifloxacin crosses the placenta (Ozyüncü 2010a; Ozyüncü 2010b). The amount of moxifloxacin available systemically following topical application of the ophthalmic drops is limited and significantly less in comparison to oral or IV doses.
If ophthalmic agents are needed during pregnancy, the minimum effective dose should be used in combination with punctal occlusion for 3 to 5 minutes after application to decrease potential exposure to the fetus (Samples 1988).
It is not known if moxifloxacin is present in breast milk following ophthalmic administration.
The amount of moxifloxacin available systemically following topical application is limited. According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and the benefits of treatment to the mother.
Moxifloxacin is a DNA gyrase inhibitor, and also inhibits topoisomerase IV. DNA gyrase (topoisomerase II) is an essential bacterial enzyme that maintains the superhelical structure of DNA. DNA gyrase is required for DNA replication and transcription, DNA repair, recombination, and transposition; inhibition is bactericidal.
Absorption: Minimal systemic absorption; resulting serum concentration was 0.02% of that achieved with oral formulation
