Drug Monograph
USE IF: Topical antimicrobial use (e.g. otitis externa, wound irrigation in selected cases)
AVOID IF: Deep infections, systemic use, perforated tympanic membrane (ear use), inappropriate concentration
Acetic acid
Weak organic acid — topical acidification / local antimicrobial adjunct (use is product- and concentration-specific)
Indication
Otitis externa • Topical antimicrobial use • Wound/irrigation (selected)
INDICATIONS (CORE USE)
- Otitis externa (ear drops) - Topical antimicrobial use - Wound/irrigation in selected contexts
ADULT DOSE (STANDARD)
STANDARD: Use appropriate concentration depending on indication Onset: local effect
MAX DOSE
Concentration-limited — follow product-specific limits; avoid high-strength or undiluted use unless explicitly indicated
Route
Topical • Irrigation
PEDIATRIC DOSE
Use appropriate formulations; see product labeling and pediatric guidance
Must-not-miss safety points
Major warning
- Concentration-dependent toxicity - Can cause irritation or chemical injury if misused - Not for systemic infection - Avoid in perforated tympanic membrane
INDICATION: Otitis externa • Topical antimicrobial use • Wound/irrigation (selected)
Primary
Secondary
STANDARD (ADULT PO)
Use appropriate concentration depending on indication and product
ADULT DOSE
STANDARD: - Use appropriate concentration for the indication (otic vs wound/irrigation products differ) - Not a systemic antimicrobial — adjuvant / local therapy only when appropriate
PEDIATRIC DOSE
Use appropriate formulations; see labeling and pediatric ENT/wound pathways
MAX DOSE
Defined by product strength and site of use — do not exceed labeled concentration or duration without specialist input
Practical Note
- Do NOT use undiluted unless specifically indicated by the intended product and protocol - Follow product-specific concentrations and application rules
Clinical warnings
Adverse effects
Pediatrics
Use appropriate formulations; see product labeling and pediatric guidance
Pregnancy
Pregnancy /
Lactation
Topical/otic use: follow product labeling; minimize unnecessary prolonged mucosal exposure per clinician judgment.
Renal impairment
Not a primary issue for standard topical/otic use; systemic load negligible when used as labeled
Hepatic impairment
Not a primary issue for standard topical/otic use; see labeling if massive unusual exposure is suspected
Elderly
Same concentration and mucosal injury cautions; verify otic candidacy and TM status when feasible
- Topical application (site-specific) or irrigation per protocol - Follow correct dilution / labeled concentration - Avoid use beyond indication (not for deep/ systemic infection as sole therapy)
Clinical Picture
Local irritation or injury
Immediate Actions
Stop exposure Irrigate area if appropriate per protocol and site
Antidote
None specific
Decontamination
Remove residual product; copious water irrigation for cutaneous/mucosal exposure per severity
Escalation
Severe chemical injury, uncontrolled pain, or eye involvement — escalate to acute care / specialty
