What Is Ciprofloxacin And Dexamethasone Used For?
1 INDICATIONS AND USAGE Ciprofloxacin and dexamethasone otic suspension is indicated for the treatment of infections caused by susceptible isolates of the designated microorganisms in the specific condition listed below: Acute Otitis Externa (AOE) in pediatric (age 6 months and older), adult and elderly patients due to Staphylococcus aureus and Pseudomonas aeruginosa. Ciprofloxacin and dexamethasone otic suspension is a combination of ciprofloxacin, a fluoroquinolone antibacterial and dexamethasone, a corticosteroid, indicated for the treatment of infections caused by susceptible isolates of the designated microorganisms in the specific condition listed below: Acute Otitis Externa (AOE) in pediatric (age 6 months and older), adult, and elderly patients due to Staphylococcus aureus and Pseudomonas aeruginosa .

Dosage and Administration
2 DOSAGE AND ADMINISTRATION Ciprofloxacin and dexamethasone otic suspension is for otic use (ears) only, not for ophthalmic use, or for injection. ( 2.1 ) Shake well immediately before use. ( 2.1 ) Instill four drops into the affected ear twice daily, for seven days. ( 2.2 ) 2.1 Important Administration Instructions Ciprofloxacin and dexamethasone otic suspension is for otic use (ears) only, and not for ophthalmic use, or for injection. Shake well immediately before use. 2.2 Dosage For the Treatment of Acute Otitis Externa (age 6 months and older) The recommended dosage regimen is as follows: Four drops [equivalent to 0.14 mL of ciprofloxacin and dexamethasone otic suspension, (consisting of 0.42 mg ciprofloxacin and 0.14 mg dexamethasone)] instilled into the affected ear twice daily for seven days. The suspension should be warmed by holding the bottle in the hand for one or two minutes to avoid dizziness, which may result from the instillation of a cold suspension. The patient should lie with the affected ear upward, and then the drops should be instilled. This position should be maintained for 60 seconds to facilitate penetration of the drops into the ear canal. Repeat, if necessary, for the opposite ear. Discard unused portion after therapy is completed.
Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling: Hypersensitivity Reactions [see Warnings and Precautions (5.1) ]. Potential for Microbial Overgrowth with Prolonged Use [see Warnings and Precautions (5.2) ]. Most common adverse reactions were ear discomfort (3%), ear pain (2.3%), and ear pruritus (1.5%). ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Amneal Pharmaceuticals at 1-877-835-5472 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another drug and may not reflect the rates observed in practice. In Phases II and III clinical trials, a total of 537 patients were treated with ciprofloxacin and dexamethasone otic suspension with AOE. The reported adverse reactions are listed below: Acute Otitis Externa The following adverse reactions occurred in 0.4% or more of the patients with intact tympanic membranes. Adverse Reactions Incidence (N = 537) Ear pruritus 1.5% Ear debris 0.6% Superimposed ear infection 0.6% Ear congestion 0.4% Ear pain 0.4% Erythema 0.4% The following adverse reactions were each reported in a single patient: ear discomfort; decreased hearing; and ear disorder (tingling). 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of ciprofloxacin and dexamethasone otic suspension. Because these reactions are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These reactions include auricular swelling, headache, hypersensitivity, otorrhea, skin exfoliation, rash erythematous, and vomiting.

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary There are no available data on ciprofloxacin and dexamethasone otic suspension use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Because of the minimal systemic absorption of ciprofloxacin and dexamethasone following topical otic administration of ciprofloxacin and dexamethasone otic suspension, this product is expected to be of minimal risk for maternal and fetal toxicity when administered to pregnant women [see Clinical Pharmacology (12.3) ] . Animal reproduction studies have not been conducted with ciprofloxacin and dexamethasone otic suspension. Oral administration of ciprofloxacin during organogenesis at doses up to 100 mg/kg to pregnant mice and rats, and up to 30 mg/kg to pregnant rabbits did not cause fetal malformations (see Data). These doses were at least 200 times the recommended otic human dose (ROHD in mice, rats, and rabbits, respectively, based on body surface area (BSA). With dexamethasone, malformations have been observed in animal studies after ocular and systemic administration. 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. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and of miscarriage is 15% to 20% respectively. Data Animal Data Ciprofloxacin Developmental toxicology studies have been performed with ciprofloxacin in rats, mice, and rabbits. The doses used in these studies are, at a minimum, approximately 200 times greater than the recommended otic human dose based on body surface area. In rats and mice, oral doses up to 100 mg/kg administered during organogenesis (Gestation Days (GD), 6 to 17) were not associated with adverse developmental outcomes, including embryo-fetal...
Overdosage
10 OVERDOSAGE Due to the characteristics of this preparation, no toxic effects are to be expected with an otic overdose of this product.
