Can't find or afford Ertaczo? Here are the best alternatives to Sertaconazole for athlete's foot, including OTC and prescription options.
If your doctor prescribed Ertaczo (Sertaconazole Nitrate) cream for athlete's foot or another fungal skin infection, but you can't find it at your pharmacy — or the price is more than you can afford — you're not stuck. Several effective antifungal alternatives are available, many of which are significantly cheaper and easier to find.
In this guide, we'll explain what Ertaczo is, how it works, and walk you through the best alternative medications you can discuss with your doctor.
Ertaczo is a prescription topical cream containing 2% Sertaconazole Nitrate. It's an azole antifungal approved by the FDA for the treatment of interdigital tinea pedis (athlete's foot between the toes) in patients 12 years and older. Doctors also prescribe it off-label for conditions like ringworm (tinea corporis), jock itch (tinea cruris), and tinea versicolor.

Ertaczo has a dual mechanism of action that sets it apart from many other antifungals:
This two-pronged approach means Ertaczo can be both fungistatic (stops fungal growth) and fungicidal (kills fungi) depending on the concentration and the organism. It also has anti-inflammatory properties, which can help with the itching and redness that come with fungal infections.

There are several common reasons patients look for Ertaczo alternatives:
The following medications treat the same types of fungal infections as Ertaczo. Always talk to your doctor before switching medications — they can help you choose the best option for your specific condition.
Drug class: Allylamine antifungal
How it works: Terbinafine inhibits the enzyme squalene epoxidase, blocking ergosterol synthesis at a different step than azole antifungals like Ertaczo. This makes it fungicidal — it kills the fungus rather than just stopping its growth.
Available forms: OTC cream, gel, and spray. Also available as prescription oral tablets for severe infections.
Typical use: Apply once or twice daily for 1-4 weeks depending on the condition.
Cost: $8-$15 OTC at most pharmacies. No prescription needed for the topical form.
Why consider it: Terbinafine is widely considered the gold standard for athlete's foot treatment. It's effective, affordable, and available without a prescription. Studies show cure rates comparable to or better than many prescription antifungals for tinea pedis.
Drug class: Azole antifungal (imidazole) — same class as Ertaczo
How it works: Like Ertaczo, Clotrimazole inhibits ergosterol synthesis by blocking the 14-alpha-demethylase enzyme. However, it does not have Ertaczo's secondary membrane-disrupting mechanism.
Available forms: OTC cream, solution, and powder.
Typical use: Apply twice daily for 2-4 weeks.
Cost: $8-$15 OTC. Generic versions are even cheaper.
Why consider it: Clotrimazole is one of the most widely available and affordable antifungals on the market. It's effective for mild to moderate athlete's foot, jock itch, and ringworm. Because it's in the same drug class as Ertaczo, it works through a similar mechanism.
Drug class: Allylamine antifungal
How it works: Similar to Terbinafine, Naftifine inhibits squalene epoxidase. It also has anti-inflammatory properties, much like Ertaczo.
Available forms: Prescription cream (1% and 2%) and gel (1% and 2%).
Typical use: Apply once or twice daily for 2-4 weeks depending on the formulation and condition.
Cost: Brand-name Naftin costs $400-$700, but generic Naftifine is available and significantly cheaper at around $30-$80 with a discount card.
Why consider it: Naftifine is a good choice if you want a prescription-strength antifungal with anti-inflammatory benefits similar to Ertaczo, but at a lower cost thanks to generic availability.
Drug class: Azole antifungal
How it works: Luliconazole inhibits the same 14-alpha-demethylase enzyme as Ertaczo but has enhanced potency against dermatophytes.
Available forms: Prescription cream 1%.
Typical use: Apply once daily for 2 weeks (tinea pedis) or 1 week (tinea cruris).
Cost: Brand-name Luzu costs $500-$800. No generic is currently available in the U.S.
Why consider it: If your doctor specifically wants you on a prescription azole antifungal, Luliconazole offers the convenience of once-daily dosing and a shorter treatment course than Ertaczo. However, it shares the same high-cost and limited-availability challenges.
The best alternative depends on your situation:
Not being able to fill your Ertaczo prescription is frustrating, but it doesn't mean you have to go without treatment. Multiple effective antifungals are available — some without a prescription and for a fraction of the cost. Talk to your doctor about which alternative makes the most sense for your condition, and use Medfinder to find whatever medication you need in stock at a pharmacy near you.
