Product Overview

Dealing with athlete's foot or toenail fungus can be uncomfortable and persistent. The SFEIXE Extra Strength Athlete's Foot & Toenail Fungus Treatment Pen offers a powerful yet convenient solution. Formulated with 25% undecylenic acid—the maximum strength available without a prescription—this treatment works to eliminate fungus and provide relief from itching, burning, and cracking. The pen-style applicator allows for precise, mess-free application directly to the affected areas, making it ideal for both feet and nails.

Key Features and Benefits

  • Maximum Strength Formula: Contains 25% undecylenic acid, the highest concentration available OTC for effective antifungal action.
  • Dual Action for Feet & Nails: Treats both athlete's foot (tinea pedis) and toenail fungus (onychomycosis) with one product.
  • Precision Applicator Pen: Easy-to-use pen design allows targeted application to affected skin and nails without mess or waste.
  • Fast Itch Relief: Starts working immediately to soothe itching, burning, and discomfort associated with fungal infections.
  • FSA/HSA Eligible: Can be purchased with Flexible Spending Account or Health Savings Account funds.
  • Convenient 3-Pack: Three 0.11 fl oz pens provide a full treatment course or multiple applications for ongoing care.

How to Use

For best results, clean and dry the affected area thoroughly. Twist the base of the pen to dispense the solution onto the applicator tip. Apply a thin layer to the affected skin or nail and the surrounding area. Use twice daily (morning and evening) for at least 4 weeks for athlete's foot, and up to 12 weeks for toenail fungus. Continue use for the full recommended duration even if symptoms improve, to prevent recurrence.

Who It Is For

This treatment is designed for adults experiencing athlete's foot symptoms such as itching, scaling, and cracking between the toes, as well as those with toenail fungus characterized by discoloration, thickening, or crumbling of the nail. It is suitable for individuals seeking an effective over-the-counter solution that is easy to apply and fits into a daily routine.

Why Choose This Product

Unlike many antifungal treatments that contain lower concentrations of active ingredients, SFEIXE Extra Strength Pen delivers 25% undecylenic acid for maximum potency. The precision pen applicator reduces mess and ensures you treat only the affected area, minimizing waste. Plus, with FSA/HSA eligibility, it's a cost-effective choice for those with health spending accounts. The convenient 3-pack ensures you have enough product to complete the full treatment course.
