Blis-To-Sol Powder Availability Update: What Patients Need to Know in 2026

If you've been using Blis-To-Sol Powder for athlete's foot or another fungal skin infection and you're suddenly having trouble finding it, you're not alone. Patients across the U.S. have reported difficulty locating this OTC antifungal powder at their usual pharmacies. Here's an honest 2026 update.

Is Blis-To-Sol Powder in a Shortage in 2026?

The short answer: No. Blis-To-Sol Powder is not listed on the FDA Drug Shortage Database as of 2026. The FDA tracks drug shortages for regulated pharmaceuticals — primarily prescription medications with limited manufacturers. As an OTC product, Blis-To-Sol Powder isn't subject to the same formal shortage designation process.

That said, the lack of a formal shortage designation doesn't mean it's easy to find. The product's limited distribution through its manufacturer, Oakhurst Co., means it simply isn't stocked at most major retail pharmacy chains.

Why Blis-To-Sol Powder Can Be Hard to Find

Understanding why Blis-To-Sol Powder has inconsistent availability helps you find it faster:

Smaller manufacturer. Oakhurst Co. is a regional specialty manufacturer, not a large national pharmaceutical company. Their distribution network is more limited than brands like Tinactin or Lamisil AT.

Limited shelf space allocation. Major pharmacy chains prioritize OTC antifungals with large advertising budgets. Blis-To-Sol competes for limited shelf space and often loses out to nationally marketed brands.

Seasonal demand. Athlete's foot infections peak in warm months. Even stores that carry Blis-To-Sol Powder can temporarily run out during summer demand spikes.

Supply chain variability. OTC manufacturers, especially smaller ones, can face raw material delays and packaging supply issues that temporarily affect availability.

What Makes Blis-To-Sol Powder Different From Other OTC Antifungals?

Blis-To-Sol Powder contains undecylenic acid with zinc undecylenate — one of the oldest OTC antifungal ingredients. Despite its age, research supports its effectiveness. A systematic review published in the Cochrane Database found undecylenic acid achieved a 72% clinical cure rate for athlete's foot — the highest among OTC antifungal options studied.

The powder formulation provides an additional benefit: it absorbs moisture in the foot environment, which is important because fungus thrives in warm, moist conditions. Using an antifungal powder can both treat the infection and reduce the environment that allows it to persist.
