Ertaczo (Sertaconazole Nitrate) is a prescription topical antifungal cream used to treat interdigital tinea pedis (athlete's foot) in adults and children 12 years and older. It belongs to the imidazole class of azole antifungals and is applied directly to the affected skin between the toes and surrounding area. Ertaczo is FDA-approved for athlete's foot caused by Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum. It may also be prescribed off-label for other fungal skin infections such as ringworm, jock itch, and cutaneous candidiasis.

Need this medication?
Ertaczo works through a dual mechanism of action. First, Sertaconazole inhibits cytochrome P450 14-alpha-demethylase, an enzyme fungi need to produce ergosterol — a critical component of their cell membranes. Blocking this enzyme weakens the fungal cell wall, causing it to leak and die. Second, Sertaconazole binds directly to nonsterol lipids in the fungal cell membrane, further increasing permeability. Ertaczo also has anti-inflammatory properties, working through a p38-COX-2-PGE2 pathway, which can help reduce redness and irritation at the infection site. This combination of antifungal and anti-inflammatory activity sets it apart from many other topical antifungals.
Ertaczo Cream 2% — cream
Each gram contains 17.5 mg of Sertaconazole (as Sertaconazole Nitrate 20 mg) in a white cream base. Available in tubes for topical application.
Ertaczo scores a 45 out of 100 on our findability scale, meaning it can be moderately difficult to locate. As a brand-only topical antifungal with no generic equivalent available in the United States, Ertaczo has limited distribution and is not routinely stocked at most retail pharmacies. You may need to call multiple pharmacies or request a special order. Availability tends to be more consistent at larger chain pharmacies or specialty pharmacies. If your pharmacy doesn't carry it, ask them to order it — most can get it within a few business days.
Ertaczo is most commonly prescribed by dermatologists and podiatrists, who frequently treat fungal skin and foot infections. However, primary care physicians, family medicine doctors, and internists can also prescribe it. Because Ertaczo is a prescription medication, you'll need to see a healthcare provider — telehealth visits are also an option for getting a prescription. If OTC antifungals like Clotrimazole or Terbinafine haven't worked, your doctor may recommend Ertaczo as a next step.
No. Ertaczo is not a controlled substance and has no DEA scheduling. It is a topical antifungal cream with no potential for abuse or dependence. No special prescribing restrictions apply — any licensed prescriber can write a prescription for Ertaczo.
Ertaczo is generally well tolerated as a topical medication. Side effects tend to be mild and localized to the application site:
If you experience severe irritation or an allergic reaction, stop using Ertaczo and contact your healthcare provider. People with known sensitivity to other azole antifungals should use Ertaczo with caution due to possible cross-reactivity.

Prefer Ertaczo? We can find it.
Ertaczo is a unique prescription antifungal cream with dual antifungal and anti-inflammatory properties, making it a solid option for athlete's foot — especially when OTC treatments have failed. However, its high cost ($897–$1,070 without insurance) and limited availability as a brand-only product can make it challenging to obtain. Discount cards from GoodRx and InsideRx can bring the price closer to $447. For many patients, affordable OTC alternatives like Terbinafine (Lamisil) or Clotrimazole (Lotrimin) may be worth trying first. If you do need Ertaczo, use Medfinder to locate pharmacies with it in stock near you.
