🩺 Clinical
Ciprofloxacin ophthalmic solution is used to treat bacterial infections of the eye including conjunctivitis (pinkeye; infection of the membrane that covers the outside of the eyeball and the inside of the eyelid) and corneal ulcers (infection and loss of tissue in the clear front part of the eye). Ciprofloxacin ophthalmic ointment is used to treat conjunctivitis. Ciprofloxacin is in a class of antibiotics called fluoroquinolones. It works by killing the bacteria that cause infection.

📄 Full prescribing information FDA SPL
🎯 Indications and Usage ▾
INDICATIONS AND USAGE: CILOXAN ® (ciprofloxacin ophthalmic ointment) 0.3% is indicated for the treatment of bacterial conjunctivitis caused by susceptible strains of the microorganisms listed below: Gram-Positive: Staphylococcus aureus Staphylococcus epidermidis Streptococcus pneumoniae Streptococcus Viridans Group Gram-Negative: Haemophilus influenzae
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION: Apply a ½ inch ribbon into the conjunctival sac three times a day on the first two days, then apply a ½ inch ribbon two times a day for the next five days.
⛔ Contraindications ▾
CONTRAINDICATIONS: A history of hypersensitivity to ciprofloxacin or any other component of the medication is a contraindication to its use. A history of hypersensitivity to other quinolones may also contraindicate the use of ciprofloxacin.
⚠️ Warnings ▾
WARNINGS: FOR EYE USE ONLY NOT FOR INJECTION INTO THE EYE Serious and occasionally fatal hypersensitivity (anaphylactic) reactions, some following the first dose, have been reported in patients receiving systemic quinolone therapy. Some reactions were accompanied by cardiovascular collapse, loss of consciousness, tingling, pharyngeal or facial edema, dyspnea, urticaria, and itching. Only a few patients had a history of hypersensitivity reactions.
Serious anaphylactic reactions require immediate emergency treatment with epinephrine and other resuscitation measures, including oxygen, intravenous fluids, intravenous antihistamines, corticosteroids, pressor amines, and airway management, as clinically indicated.
🤒 Adverse Reactions ▾
ADVERSE REACTIONS: The following adverse reactions (incidences) were reported in 2% of the patients in clinical studies for CILOXAN ® (ciprofloxacin ophthalmic ointment) 0.3%: discomfort and keratopathy. Other reactions associated with ciprofloxacin therapy occurring in less than 1% of patients included allergic reactions, blurred vision, corneal staining, decreased visual acuity, dry eye, edema, epitheliopathy, eye pain, foreign body sensation, hyperemia, irritation, keratoconjunctivitis, lid erythema, lid margin hyperemia, photophobia, pruritus, and tearing.
Systemic adverse reactions related to ciprofloxacin therapy occurred at an incidence below 1% and included dermatitis, nausea and taste perversion.
🔄 Drug Interactions ▾
Drug Interactions: Specific drug interaction studies have not been conducted with ophthalmic ciprofloxacin. However, the systemic administration of some quinolones has been shown to elevate plasma concentrations of theophylline, interfere with the metabolism of caffeine, enhance the effects of the oral anticoagulant, warfarin, and its derivatives, and has been associated with transient elevations in serum creatinine in patients receiving cyclosporine concomitantly.
🤰 Pregnancy ▾
Pregnancy: Reproduction studies have been performed in rats and mice at doses up to six times the usual daily human oral dose and have revealed no evidence of impaired fertility or harm to the fetus due to ciprofloxacin. In rabbits, as with most antimicrobial agents, ciprofloxacin (30 and 100 mg/kg orally) produced gastrointestinal disturbances resulting in maternal weight loss and an increased incidence of abortion. No teratogenicity was observed at either dose.
After intravenous administration, at doses up to 20 mg/kg, no maternal toxicity was produced and no embryotoxicity or teratogenicity was observed. There are no adequate and well controlled studies in pregnant women. CILOXAN ® (ciprofloxacin ophthalmic ointment) 0.3% should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
🧒 Pediatric Use ▾
Pediatric Use: Safety and effectiveness of CILOXAN ® (ciprofloxacin ophthalmic ointment) 0.3% in pediatric patients below the age of two years have not been established. Although ciprofloxacin and other quinolones may cause arthropathy in immature Beagle dogs after oral administration, topical ocular administration of ciprofloxacin to immature animals did not cause any arthropathy and there is no evidence that the ophthalmic dosage form has any effect on the weight bearing joints.
🧓 Geriatric Use ▾
Geriatric Use: No overall clinical differences in safety or effectiveness have been observed between the elderly and other adult patients.
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY: Systemic Absorption: Absorption studies in humans with the ciprofloxacin ointment have not been conducted, however, based on studies with ciprofloxacin solution, 0.3%, mean maximal concentrations are expected to be less than 2.5 ng/mL. Microbiology: Ciprofloxacin has in vitro activity against a wide range of gram-negative and gram-positive organisms. The bactericidal action of ciprofloxacin results from interference with the enzyme DNA gyrase which is needed for the synthesis of bacterial DNA.
Ciprofloxacin has been shown to be active against most strains of the following microorganisms both in vitro and in clinical infections (see INDICATIONS AND USAGE section). Aerobic gram-positive microorganisms: Staphylococcus aureus (methicillin-susceptible strains) Staphylococcus epidermidis (methicillin-susceptible strains) Streptococcus pneumoniae Streptococcus Viridans Group Aerobic gram-negative microorganisms: Haemophilus influenzae The following in vitro data are available; but their clinical significance in ophthalmologic infections is unknown .
The safety and effectiveness of ciprofloxacin in treating conjunctivitis due to these microorganisms have not been established in adequate and well-controlled trials. The following organisms are considered susceptible when evaluated using systemic breakpoints. However, a correlation between the in vitro systemic breakpoint and ophthalmological efficacy has not been established.
Ciprofloxacin exhibits in vitro minimal inhibitory concentrations (MIC’s) of 1 mcg/mL or less (systemic susceptible breakpoint) against most (greater than or equal to 90%) strains of the following ocular pathogens. Aerobic gram-positive microorganisms: Bacillus species Corynebacterium species Staphylococcus haemolyticus Staphylococcus hominis Aerobic gram-negative microorganisms: Acinetobacter calcoaceticus Enterobacter aerogenes Escherichia coli Haemophilus parainfluenzae Klebsielle pneumoniae Moraxella catarrhalis Neisseria gonorrhoeae Proteus mirabilis Pseudomonas aeruginosa Serratia marcesens Most strains of Burkholderia cepacia and some strains of Stenotrophomonas maltophilia are resistant to ciprofloxacin as are most anaerobic bacteria, including Bacteroides fragilis and Clostridium difficile .
The minimal bactericidal concentration (MBC) generally does not exceed the minimal inhibitory concentration (MIC) by more than a factor of 2. Resistance to ciprofloxacin in vitro usually develops slowly (multiple-step mutation). Ciprofloxacin does not cross-react with other antimicrobial agents such as beta-lactams or aminoglycosides; therefore, organisms resistant to these drugs may be susceptible to ciprofloxacin.
Organisms resistant to ciprofloxacin may be susceptible to beta-lactams or aminoglycosides. Clinical Studies: In multi-center clinical trials, approximately 75% of the patients with signs and symptoms of bacterial conjunctivitis and positive conjunctival cultures were clinically cured and approximately 80% had presumed pathogens eradicated by the end of treatment (Day 7).
