Description
Fungi-Nail® Pen goes to work on your toe fungus, eliminating fungal infections on cuticles, around nail edges and tips, and between the toes where if left unchecked it can spread. Fungi-Nail® Pen is formulated with a 25% Undecylenic Acid, the maximum strength available over-the-counter. The clear, water resistant barrier locks the medicine in while the pen applicator targets the treatment right where you need it.
Frequently Asked Questions
What is this product and what is it used for?
This is a topical antifungal solution containing 25% undecylenic acid, the maximum OTC strength, formulated to treat fungal infections of the fingernails and toenails as well as athlete's foot. It comes with a brush applicator designed to apply the solution precisely along the nail edge, cuticle, and tip. It suits adults with early-stage nail fungus (onychomycosis) or athlete's foot looking for a non-prescription topical option.
What is the active ingredient and how does it work?
The active ingredient is 25% undecylenic acid, a fatty acid derivative that works fungistatically — inhibiting fungal growth by disrupting ergosterol synthesis in the fungal cell membrane rather than directly killing the fungus. Other ingredients include emulsifying wax, mineral oil, and petrolatum, which form a clear, waterproof barrier intended to keep the medication in contact with the treated area longer.
How should this be applied and what results can be expected?
Clean the affected area with soap and water, then apply a thin layer with the brush under the nail edge and cuticle, morning and night, for at least 4 weeks. Clinical experience with undecylenic acid shows roughly 40-60% clearance in mild-to-moderate infections over 6-12 months of consistent use, as topical treatments have difficulty reaching fungus deep under the nail plate; more severe or long-standing infections may need medical evaluation.
How does this liquid solution differ from cream or stick formats of the same treatment?
Compared to Fungi-Nail's ointment or portable stick formats using the same 25% undecylenic acid, this liquid solution with brush applicator allows more precise, targeted application directly under the nail edge and cuticle — areas creams typically struggle to penetrate. The liquid's lower viscosity also lets it flow into small gaps around the nail, which may make it better suited for hard-to-reach infection sites than thicker cream formulations.
What is Fungi-Nail and what does the brand treat?
Fungi-Nail is an over-the-counter antifungal brand designed to treat and prevent nail fungus, athlete's foot, and ringworm. The active ingredient is Undecylenic Acid 25%, a fatty acid derived from castor oil that disrupts the cell membrane of fungal organisms. The brand offers multiple application formats — ointment, liquid, and pen applicator — each with a dual-angle brush or precision tip designed to reach under nail tips and into the cuticle area. The recommended course is twice daily for four weeks. Fungi-Nail is available through major Canadian pharmacies.
What makes Fungi-Nail different from other antifungal nail treatments?
Fungi-Nail uses Undecylenic Acid (25%) as its active ingredient rather than the more common azole antifungals or terbinafine. Undecylenic acid has a long history of use and works as a fungistatic agent — it inhibits fungal growth rather than relying solely on a cell-killing mechanism, which may reduce the risk of resistance over repeated use. The brand's physical applicator design — a narrow edge for under-nail application and a wide edge for the surrounding skin — is purpose-built for the complex geometry of nail fungal infections. Most generic antifungal creams do not address the under-nail area with this level of precision.
