From the FDA Drug Label

Ciprofloxacin otic solution, 0.2% should be given 2 times each day (about 12 hours apart) in each infected ear.

The recommended dose of ciprofloxacin for otorrhoea associated with grommets is 0.2% otic solution, 2 times a day (about 12 hours apart) in each infected ear 1.

  • Key points:
    • Dosage: 0.2% otic solution
    • Frequency: 2 times a day
    • Administration: in each infected ear
  • Important consideration: The patient should be advised to follow the directions for use as prescribed, even if the symptoms improve.

From the Research

For grommet-associated otorrhea, ciprofloxacin ear drops (0.3%) are typically recommended at a dose of 3-4 drops into the affected ear twice daily for 7-10 days, as supported by the most recent and highest quality study 2.

Key Considerations

  • The dose and duration of ciprofloxacin ear drops may vary depending on the patient's age and response to treatment.
  • It is essential to warm the drops to room temperature before administration to prevent dizziness, especially in children.
  • When administering, the patient should lie with the affected ear upward, and the drops should be instilled and maintained in this position for 3-5 minutes to allow proper distribution.
  • Gently pulling the ear lobe backward and upward for adults (or downward and backward for children) can help straighten the ear canal.

Rationale

  • Ciprofloxacin is effective against common pathogens causing otorrhea, including Pseudomonas aeruginosa, while minimizing systemic absorption 3.
  • Topical treatment is preferred over oral antibiotics as it delivers a higher concentration of medication directly to the infection site with fewer systemic side effects.
  • The most recent study 2 found that intraoperative topical ciprofloxacin was effective at preventing early postoperative otorrhea, and a prolonged course was effective at preventing ventilation tube obstruction.

Additional Guidance

  • If symptoms persist beyond 10 days or worsen, medical reassessment is necessary to determine the best course of action.
  • Future studies should seek to clarify whether particular subgroups of patients benefit more from prophylactic topical antibiotics and model for cost-effectiveness 2.
