Ciprofloxacin Otic Ear Infection Uses Side Effects Dosage

ciprofloxacin otic

Ciprofloxacin otic is an antibiotic used to treat external ear infection (otitis externa) in adults and children, and middle ear infection (otitis media) in children. Ciprofloxacin is a broad-spectrum, second-generation fluoroquinolone effective against Gram-negative and Gram-positive bacteria. Gram-negative bacteria have an additional cell membrane outside the cell wall that Gram-positive bacteria lack.

Similar to other quinolones, ciprofloxacin otic kills susceptible bacteria by preventing the synthesis and replication of bacterial DNA. Ciprofloxacin inhibits gyrase, an enzyme essential for bacterial DNA synthesis. Ciprofloxacin otic binds to the broken strands of bacterial DNA and prevents their recombination, resulting in bacterial cell death.

Bacteria may develop resistance to ciprofloxacin. Ciprofloxacin is active against organisms resistant to other antibiotic classes.

Ciprofloxacin otic is approved by the FDA to treat acute otitis externa in patients 6 months and older due to Pseudomonas aeruginosa and Staphylococcus aureus – both Cetraxal and Otiprio brands. It is also used in pediatric patients (age 6 months and older) with bilateral otitis media with effusion undergoing ear tube surgery (tympanostomy tube placement) – Otiprio only.

Organisms susceptible to ciprofloxacin include Haemophilus influenzae, Moraxella catarrhalis, and Pseudomonas aeruginosa.

Warnings

  • Do not use ciprofloxacin otic in patients with a history of hypersensitivity to ciprofloxacin or any other quinolones. Discontinue ciprofloxacin otic at the first sign of skin rash or other signs of hypersensitivity.
  • Use only Otiprio brand of ciprofloxacin otic for treatment of children with bilateral otitis media with effusion undergoing tympanostomy tube placement.
  • Use of ciprofloxacin otic may result in overgrowth of susceptible organisms. Use alternate therapy if the patient develops such superinfections.
  • If otitis externa is not resolved after a week of treatment with ciprofloxacin otic, culture tests may be required to determine further treatment.
