📖 Sertaconazole Topical: Patient Information Guide

A plain-language walkthrough of Sertaconazole Topical — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.

🎯What it's used for

Sertaconazole topical is an antifungal medication. Based on the available product evidence, it is approved for the following use:

  • Ertaczo cream, 2%: Topical treatment of interdigital tinea pedis (athlete's foot between the toes) in immunocompetent adults and pediatric patients 12 years of age and older, caused by Trichophyton rubrum, Trichophyton mentagrophytes, or Epidermophyton floccosum.
⚙️How it works

Sertaconazole is an azole antifungal. It targets a fungal enzyme — cytochrome P-450-mediated 14 alpha-lanosterol demethylase — that the fungus needs to convert lanosterol into ergosterol. Ergosterol is an essential building block of the fungal cell membrane. Without it, the membrane becomes unstable, starts to leak vital cell contents, and the fungal cell is damaged and dies.

In clinical studies, sertaconazole nitrate has shown activity specifically against Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum — the fungi that most commonly cause interdigital tinea pedis.

💊How it's taken

Ertaczo cream, 2% is applied directly to the skin (topical use only) twice a day for 4 weeks. Apply enough to cover the affected skin between the toes and the healthy skin right around it. This cream is not taken by mouth and is not used in the eyes or vaginal area.

  • Dry the area thoroughly before each application, especially after bathing.
  • Wash hands after applying.
  • Do not wrap or cover the treated area tightly.
  • Finish the full 4-week course even if your symptoms improve — stopping early raises the chance the infection comes back.
🤒Side effects — in detail

Most people tolerate Ertaczo cream well. The side effects reported in clinical trials were generally mild and occurred at similar rates to the inactive cream used for comparison.

  • Contact dermatitis (skin irritation or rash)
  • Dry skin
  • Burning sensation on the skin
  • Tenderness at the application site
  • Redness (erythema) — reported after the product was on the market
  • Itching (pruritus) — reported after the product was on the market
  • Small blisters (vesiculation) — reported after the product was on the market
  • Skin peeling (desquamation) — reported after the product was on the market
  • Darkening of the skin (hyperpigmentation) — reported after the product was on the market

If irritation worsens or a significant skin reaction develops, stop using the cream and contact your doctor right away.

⚠️Warnings & precautions
  • Skin irritation: If irritation develops at the application site, discontinue use and seek medical advice. Do not push through a worsening skin reaction.
  • Azole cross-sensitivity: If you have previously reacted to another azole antifungal (such as clotrimazole or miconazole), tell your doctor before using sertaconazole — a similar reaction may occur.
  • Not for eyes, mouth, or vaginal use: This is a topical skin cream only. Avoid contact with these areas.
🔀What it interacts with

The FDA label for Ertaczo cream does not identify specific drug, food, or supplement interactions for topical sertaconazole.

    This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.

    📋Before taking it
    • Azole antifungal allergy: Tell your doctor if you have ever had a reaction to any azole antifungal — cross-sensitivity is possible.
    • Pregnancy: There are no human pregnancy studies for Ertaczo cream. Animal studies at high oral doses showed some concerns late in pregnancy. Discuss the risks and benefits with your doctor.
    • Breastfeeding: It is not known whether sertaconazole passes into breast milk. Talk to your doctor about whether to continue breastfeeding while using this cream.
    • Children under 12: The safety and effectiveness of Ertaczo cream have not been established in patients younger than 12 years old.
    • Adults 65 and older: Clinical trials did not include enough older adults to confirm whether they respond differently. Use with your doctor's guidance.
    • Weakened immune system: Ertaczo cream is approved only for patients with a normally functioning immune system (immunocompetent patients). If your immune system is weakened, talk to your doctor before use.
    🔬Pharmacokinetics — how your body processes it

    In a clinical study using Ertaczo cream, 2%, the cream was applied twice daily to the affected skin of people with interdigital tinea pedis. After multiple doses, blood levels of sertaconazole were below the detectable limit — meaning the medication was not meaningfully absorbed into the bloodstream through diseased skin at the amounts studied. This suggests that when used as directed on the skin, very little of the drug enters the body systemically.

    📦How to store it

    Store at 20° to 25°C (68° to 77°F); excursions permitted to 15° to 30°C (59° to 86°F) .

    🩺 Pharmacist Counseling Corner

    Quick, plain-English answers to the questions patients ask most about Sertaconazole Topical — the kind of thing our pharmacy team would talk through with you at the counter.

    What exactly is this cream for?
    Ertaczo cream is specifically for treating athlete's foot between the toes — the medical term is interdigital tinea pedis. It targets the fungi that most often cause this infection. It's approved for adults and kids 12 and older who have a normally functioning immune system.
    How long do I need to use it, and what if my feet already feel better?
    You need to use it twice a day for the full 4 weeks, even if your skin clears up sooner. Stopping early is one of the most common reasons athlete's foot comes back. Think of the first week or two as knocking out most of the fungus — the rest of the course finishes the job.
    Is there anything special I need to do before applying it?
    Yes — make sure the skin between your toes is completely dry before you apply the cream, especially if you've just bathed or showered. Apply enough cream to cover both the infected areas and the healthy skin right around them. Wash your hands after each application, and don't wrap the area tightly — avoid bandages or occlusive coverings.
    What side effects should I watch for, and when should I call my doctor?
    Mild burning, dryness, or slight tenderness where you apply the cream can happen and is usually not a reason to stop. But if you notice significant irritation — worsening redness, a rash, blistering, or the skin getting much worse — stop using the cream and call your doctor. That kind of reaction can mean your skin needs a different treatment.
    I've reacted to other antifungal creams before. Is this one safe for me?
    That's really important to share with your doctor before you start. Sertaconazole belongs to the azole antifungal family — the same family as clotrimazole and miconazole, among others. If you've reacted to one of those, there's a chance you could react to sertaconazole too. Your prescriber needs to know your allergy history to decide if this is the right choice for you.
    Can I use this cream if I'm pregnant or breastfeeding?
    There are no human studies on using Ertaczo cream during pregnancy, so we don't have clear safety data. Animal studies at much higher doses than you'd ever use topically did raise some concerns. Since the cream is applied to the skin and very little appears to be absorbed into the bloodstream, the risk may be low — but this is a conversation to have with your doctor so they can weigh the benefits against any potential concern for you and your baby.
    Is Sertaconazole Topical available over the counter?
    Sertaconazole Topical is dispensed by prescription according to its FDA labeling, so it isn't sold over the counter. Your prescriber and pharmacist will determine if it's appropriate for you.
    When was Sertaconazole Topical first available?
    Sertaconazole Topical has been available in the United States since at least 2003, based on FDA approval history (Drugs@FDA) and product marketing records.
    Who makes Sertaconazole Topical?
    Sertaconazole Topical is supplied by 3 manufacturers listed in the FDA NDC Directory, including Bausch Health US, LLC, Coral Way Pharma, LLC, Lacer Pharma, LLC.

    Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.
