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.
Signs to watch for
- Head tilting or shaking
- Loss of balance and coordination
- Vomiting and diarrhea
- Loss of appetite
- Redness or pain in the ear
- Signs of hearing loss (not responding to sounds)
What to do right now
- Call your veterinarian immediately.
- Do NOT put anything more into the ear unless instructed by your vet.
- If the medication was ingested, do NOT induce vomiting unless specifically told to do so.
- Your vet will examine the ear and may flush it. Supportive care for systemic symptoms may be needed.
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
