Alternatives to Acetic Acid Ear Drops If You Can't Fill Your Prescription

Acetic acid otic solution (2%) is a well-established treatment for swimmer's ear — but it's not always easy to find at your local pharmacy. If your pharmacy is out of stock or doesn't carry it, the good news is that several effective alternatives can treat the same condition.

Here's a detailed look at the best alternatives to acetic acid ear drops, with notes on cost, availability, and when each one is most appropriate.

What Acetic Acid Treats (and Why Alternatives Can Work)

Acetic acid otic treats otitis externa — an infection of the outer ear canal caused by bacteria or fungi. It works by creating an acidic environment (pH 3) that is hostile to the bacteria and fungi causing the infection. Any medication that effectively clears these same bacteria — or otherwise treats otitis externa — can serve as an alternative.

Alternative 1: Ofloxacin Otic 0.3% (Generic Floxin Otic)

Ofloxacin otic is one of the most commonly prescribed and widely available alternatives to acetic acid for swimmer's ear. It's a fluoroquinolone antibiotic that kills bacteria by inhibiting DNA replication enzymes. Ofloxacin is safe even if you have a perforated eardrum (unlike some other ear drops), making it a versatile option.

Cost: Generic ofloxacin otic can cost as little as $10–$25, making it one of the most affordable ear drop options.

Availability: Widely stocked at most pharmacies.

Best for: Most cases of bacterial otitis externa; also safe for perforated eardrums.

Alternative 2: Ciprodex (Ciprofloxacin/Dexamethasone)

Ciprodex combines ciprofloxacin (a powerful fluoroquinolone antibiotic) with dexamethasone (a corticosteroid). This combination both kills bacteria and reduces inflammation, which helps relieve ear pain, swelling, and redness faster. Clinical trials have shown clinical cure rates of 86–94% for swimmer's ear.

Cost: More expensive than acetic acid — often $100–$200 or more without insurance; generics becoming more available.

Availability: Widely stocked at most major pharmacies.

Best for: Severe swimmer's ear with significant swelling and pain; middle ear infections in children with ear tubes.

Alternative 3: Hydrocortisone/Acetic Acid (Acetasol HC, VoSol HC)

If you like the acetic acid approach but want added anti-inflammatory relief, hydrocortisone/acetic acid (Acetasol HC) is a combination product that pairs acetic acid with hydrocortisone. It treats the infection with the same acidic mechanism while hydrocortisone reduces itching, redness, and swelling. GoodRx prices for the generic start around $43.

Cost: ~$43–$200 depending on pharmacy; generic available.

Best for: Swimmer's ear with itching and inflammation; patients who want a combination product.

Alternative 4: Cortisporin Otic (Neomycin/Polymyxin B/Hydrocortisone)

Cortisporin Otic is a three-drug combination of neomycin, polymyxin B, and hydrocortisone that has been used for decades to treat swimmer's ear. It's effective but carries an important limitation: neomycin can cause ototoxicity (hearing damage) if used when the eardrum is perforated. It should only be used if your eardrum is intact.

Cost: Generic versions typically cost $20–$60.

Limitation: Do NOT use if eardrum is perforated.

Comparison Table: Acetic Acid vs. Alternatives

Acetic Acid Otic: Low cost (~$15–$40), antiseptic only, not safe for perforated eardrum, lower availability.

Ofloxacin Otic: Low cost (~$10–$25), antibiotic, safe for perforated eardrum, widely available.

Ciprodex: Higher cost (~$100–$200), antibiotic + anti-inflammatory, widely available, very effective.

Hydrocortisone/Acetic Acid: Moderate cost (~$43+), antiseptic + anti-inflammatory, not for perforated eardrum.

Cortisporin: Moderate cost (~$20–$60), antibiotic + anti-inflammatory, NOT for perforated eardrum.

Always Consult Your Doctor Before Switching

Not every alternative is appropriate for every patient. Key factors your doctor will consider include whether your eardrum is intact, how severe the infection is, your allergy history, and your age. Never switch ear drop medications without first speaking with your prescriber.
