When You Can't Get Cortisporin-Tc, These Alternatives May Help

Your doctor prescribed Cortisporin-Tc for an ear infection — but now you're stuck. Maybe your pharmacy doesn't stock it. Maybe the $234–$350 price tag without insurance is too steep. Or maybe your insurance plan simply won't cover a brand-only medication when cheaper options exist.

Whatever the reason, the good news is that there are several effective alternatives for treating bacterial ear infections. In this article, we'll explain what Cortisporin-Tc is, how it works, and walk through the most common alternatives your doctor might consider.

Important: Never switch medications on your own. Always talk to your doctor or pharmacist before making any changes to your prescribed treatment.

What Is Cortisporin-Tc?

Cortisporin-Tc is a prescription ear drop (otic suspension) that combines four active ingredients to treat bacterial ear infections:

• Colistin sulfate — an antibiotic that kills bacteria
• Neomycin sulfate — a broad-spectrum antibiotic
• Hydrocortisone acetate — a steroid that reduces inflammation, swelling, and pain
• Thonzonium bromide — a surfactant that helps the medication penetrate earwax

It's approved to treat acute otitis externa (swimmer's ear), infections in mastoidectomy and fenestration cavities, and chronic otitis media. For a deeper dive, read our article on what Cortisporin-Tc is and how to use it.

How Does Cortisporin-Tc Work?

Cortisporin-Tc works through a multi-pronged approach:

• The two antibiotics (colistin and neomycin) attack bacteria from different angles, providing broad coverage against common ear infection pathogens like Pseudomonas aeruginosa and Staphylococcus aureus
• The steroid (hydrocortisone) tamps down the inflammatory response that causes ear pain, swelling, and redness
• The surfactant (thonzonium) breaks through earwax and debris so the antibiotics can reach the infected tissue

This combination makes Cortisporin-Tc particularly effective, but similar results can often be achieved with other medications. Learn more about the science in our article on how Cortisporin-Tc works.

Alternative #1: Ofloxacin Otic Solution (Generic Floxin Otic)

Ofloxacin otic 0.3% is often the first alternative doctors consider. It's a fluoroquinolone antibiotic ear drop that's widely available and very affordable.

Key facts:

• Price: $10–$30 for a generic bottle (compared to $234+ for Cortisporin-Tc)
• Generic available: Yes — widely stocked at virtually every pharmacy
• Safe with perforated eardrums: Yes — unlike Cortisporin-Tc, ofloxacin can be used when the eardrum has a hole or tubes
• Approved for: Acute otitis externa, chronic suppurative otitis media, and acute otitis media with tympanostomy tubes
• Drawback: Does not contain a steroid, so it won't reduce inflammation on its own. Your doctor may prescribe an oral anti-inflammatory alongside it

Ofloxacin otic is the most commonly recommended first-line treatment for most bacterial ear infections and is often what insurance plans prefer.

Alternative #2: Ciprodex (Ciprofloxacin/Dexamethasone Otic)

Ciprodex is a combination of the antibiotic ciprofloxacin and the steroid dexamethasone. It's one of the most widely prescribed ear drop combinations in the United States.

Key facts:

• Brand price: ~$300 per bottle
• Generic available: Yes — generic ciprofloxacin/dexamethasone otic typically costs $50–$100
• Safe with perforated eardrums: Yes — approved for use with tympanostomy tubes
• Approved for: Acute otitis externa and acute otitis media with tympanostomy tubes
• Advantage: Combines an antibiotic and a steroid in one drop, similar to Cortisporin-Tc's approach

The generic version of Ciprodex is a strong alternative for patients who need both antibiotic and anti-inflammatory action from their ear drops.

Alternative #3: Cortisporin Otic (Neomycin/Polymyxin B/Hydrocortisone)

Cortisporin Otic is a closely related product — and many patients confuse it with Cortisporin-Tc. While the names are similar, they contain different ingredients.

Key facts:

• Price: $15–$40 for the generic version
• Generic available: Yes — widely available as neomycin/polymyxin B/hydrocortisone otic
• Safe with perforated eardrums: No — should not be used with a ruptured eardrum
• Approved for: Acute otitis externa and other bacterial ear infections
• Key difference from Cortisporin-Tc: Contains polymyxin B instead of colistin, and does not include thonzonium bromide

This is often the closest and most affordable substitute. If your ear infection is acute otitis externa and your eardrum is intact, generic Cortisporin Otic may work just as well as Cortisporin-Tc at a fraction of the cost.

Alternative #4: Cipro HC (Ciprofloxacin/Hydrocortisone Otic)

Cipro HC combines ciprofloxacin with hydrocortisone. It's another antibiotic-plus-steroid option for ear infections.

Key facts:

• Price: ~$300+ (brand only)
• Generic available: No
• Safe with perforated eardrums: No — not approved for use with ruptured eardrums or tubes
• Approved for: Acute otitis externa
• Note: Since this is also brand-only and expensive, it's generally only considered when other options haven't worked

How to Choose the Right Alternative

The best alternative depends on your specific situation. Here's a quick guide:

• If cost is the main concern: Ofloxacin otic ($10–$30) or generic Cortisporin Otic ($15–$40) are your most affordable options
• If you have a perforated eardrum or tubes: Ofloxacin otic or generic Ciprodex are the safest choices
• If you need an antibiotic + steroid combination: Generic Ciprodex or generic Cortisporin Otic are the best matches
• If you've been specifically told you need Cortisporin-Tc: Use Medfinder to find it in stock near you

Final Thoughts

Cortisporin-Tc is an effective medication, but it's not the only option for treating bacterial ear infections. If you can't find it or can't afford it, the alternatives listed above are well-established, widely available, and often much cheaper. Talk to your doctor about which one is right for you.
