Why Ear Medications Can Be Harmful
Ear medications often contain antibiotics (like gentamicin), antifungals, and corticosteroids. If ingested orally, they can cause gastrointestinal upset.
More seriously, an overdose applied directly into the ear can be absorbed systemically or cause local toxicity to the ear structures.
Aminoglycoside antibiotics (e.g., gentamicin) can cause irreversible hearing loss and kidney damage if overdosed.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
