Ciprodex: Ciprofloxacin 0.3% and dexamethasone 0.1% (7.5 mL) [contains benzalkonium chloride, edetate disodium, tyloxapol]
Mechanism of Action
Ciprofloxacin: Inhibits DNA-gyrase in susceptible organisms; inhibits relaxation of supercoiled DNA and promotes breakage of double-stranded DNA.
Dexamethasone: Decreases inflammation by suppression of neutrophil migration, decreased production of inflammatory mediators, and reversal of increased capillary permeability; suppresses normal immune response.
Otic: Ciprofloxacin: Peak: 0.1% of oral administration peak concentrations; Dexamethasone: Peak: 14% of oral administration peak concentrations
Time to Peak
Plasma: Otic: 15 minutes to 2 hours
Use: Labeled Indications
Acute otitis media: Treatment of acute otitis media in pediatric patients ≥6 months of age with tympanostomy tubes due to susceptible isolates of Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenza, Moraxella catarrhalis, and Pseudomonas aeruginosa.
Acute otitis externa: Treatment of acute otitis externa in pediatric patients ≥6 months of age and adults due to susceptible isolates of Staphylococcus aureus and Pseudomonas aeruginosa.
Hypersensitivity to ciprofloxacin, other fluoroquinolones, dexamethasone, or any component of the formulation; viral infection of the external canal, including herpes simplex infections; fungal otic infections.
Canadian labeling: Additional contraindications (not in US labeling): Hypersensitivity to other corticosteroids; parasitic otic infections.
Dosage and Administration
Acute otitis externa: Otic: Instill 4 drops into affected ear(s) twice daily for 7 days
Refer to adult dosing.
Otitis media, acute (with typmanostomy tubes): Infants ≥6 months, Children, and Adolescents: Otic: Instill 4 drops into affected ear(s) twice daily for 7 days
Otitis externa, acute: Infants ≥6 months, Children, and Adolescents: Otic: Instill 4 drops into affected ear(s) twice daily for 7 days
Otic: For otic use only; not intended for injection or ophthalmic use. Prior to instillation, bottle should be warmed in hands for 1 to 2 minutes; dizziness can occur if a cold suspension is instilled. Shake suspension well immediately before using. Patient should lie with affected ear upward and remain in this position for 60 seconds following application.
Store at 20°C to 25°C (68°F to 77°F); excursions are permitted between 15°C and 30°C (59°F and 86°F); avoid freezing. Protect from light.
There are no known significant interactions.

1% to 10%:
Dermatologic: Pruritus of ear (2%)
Otic: Otalgia (≤3%)
<1%: Auditory impairment; crying; dizziness; dysgeusia; ear redness; ear residue, debris, or precipitate; eustachian tube congestion; irritability; oral candidiasis; superinfection; tingling of the ears, tinnitus; tympanostomy tube blockage
Concerns related to adverse effects:
- Hypersensitivity: Severe and occasionally fatal hypersensitivity reactions, including anaphylaxis, have occurred with systemic fluoroquinolone therapy. Prompt discontinuation of drug should occur if skin rash or other symptoms of hypersensitivity arise.
- Superinfection: Prolonged use may result in fungal or bacterial superinfection. If superinfection occurs, discontinue use and institute appropriate therapy.
- Tendon inflammation/rupture: There have been reports of tendon inflammation and/or rupture with systemic fluoroquinolones. Exposure following otic administration is substantially lower than with systemic therapy. Discontinue at first sign of tendon inflammation or pain.
- Appropriate use: For otic use only; not intended for injection or ophthalmic use. Prior to instillation, suspension should be warmed in hands to prevent dizziness, which may occur following use of a cold solution.
Resolution of infection; if infection persists after one week of treatment, obtain cultures to guide further treatment. If otorrhea persists after a full course of therapy, or if ≥2 episodes occur within 6 months, evaluate to exclude an underlying condition (eg, cholesteatoma, foreign body, tumor).
