Aplosyn Otic Drops in Children
Aplosyn otic drops (fluocinolone acetonide, neomycin, polymyxin B) are appropriate for children aged 2 years and older with acute otitis externa, but ONLY if the tympanic membrane is intact. 1
Age Requirements
- Minimum age: 2 years - Safety and effectiveness are established for children 2-16 years of age 1
- Under 2 years: NOT recommended - Inadequate data exists for this age group, and acute otitis externa is uncommon before age 2 2, 1
Critical Contraindication: Tympanic Membrane Status
You must verify the tympanic membrane is intact before prescribing Aplosyn. The FDA label explicitly states this product should NOT be used with a perforated tympanic membrane due to the acidity causing burning/stinging and the risk of neomycin-induced ototoxicity 1.
Why This Matters:
- Neomycin causes permanent sensorineural hearing loss through cochlear damage and destruction of hair cells in the organ of Corti 1
- Despite being contraindicated, neomycin preparations are frequently prescribed inappropriately: a large study found 15% of 300,470 children with nonintact tympanic membranes (tubes or perforations) received neomycin otic preparations 3
- The ototoxicity risk increases with prolonged use, so limit treatment to 10 consecutive days maximum 1
When to Choose Safer Alternatives
For children with tympanostomy tubes or tympanic membrane perforations, use fluoroquinolone drops instead (ofloxacin or ciprofloxacin), which have no ototoxicity risk 3, 4, 5. Studies demonstrate equivalent efficacy: ofloxacin once daily achieved 93.8-97% cure rates versus 94.7-95% with neomycin/polymyxin B/hydrocortisone four times daily 4, 6.
Additional Safety Considerations
- Sulfite allergy: Aplosyn contains potassium metabisulfite, which can cause anaphylactic reactions in susceptible individuals, particularly asthmatics 1
- Cutaneous sensitization: Neomycin causes allergic skin reactions with unknown but notable incidence; watch for reddening, swelling, dry scaling, itching, or failure to heal 1
- Close clinical observation required during treatment 1
- If no improvement after 1 week, obtain cultures and consider changing therapy 1
Common Pitfall to Avoid
The most dangerous error is prescribing Aplosyn without confirming tympanic membrane integrity. Always perform otoscopy before prescribing. If you cannot visualize the tympanic membrane due to debris or cerumen, perform aural toilet first, then reassess 2.
