Miconazole 2% Foot-Fungus Products: Liquid Spray, Powder Spray & Powder
Side-by-side comparison of three miconazole nitrate 2% foot-fungus formulations by vehicle, labeled uses, treatment course, age limits and aerosol warnings.
Key differences
These products share miconazole nitrate 2%, so the most meaningful differences are vehicle and handling: liquid aerosol spray, aerosol powder spray, or loose powder. The same active concentration does not make the formats operationally identical.

Product labels can change; follow the current package. When a comparable field is missing, the table says so rather than substituting a differently defined number.
Why this is a useful like-for-like comparison
Comparisons across different antifungal drugs can be confusing because percentage strength is not a potency ranking between molecules. Here, the cited products all use miconazole nitrate 2%, allowing the vehicle to become the main comparison variable.
Liquid aerosol spray
The Walgreens record uses a liquid aerosol. It is sprayed as a thin layer and carries flammability, pressure and deliberate-inhalation warnings. This can be convenient for application without rubbing, but the aerosol handling requirements are real safety differences.
Powder aerosol spray
Lotrimin AF Powder Spray also uses an aerosol delivery system but deposits a powder rather than a liquid. It therefore combines powder-style application with pressurized-can precautions.
Loose powder
ARM & HAMMER uses a non-aerosol loose powder. That avoids pressurized-container warnings, but it changes how the product is dispensed and applied.
What does not change
A vehicle change does not turn a skin antifungal into a nail treatment. Follow the labeled treatment course, and use the nail fungus guide when the nail plate is involved rather than only the surrounding skin.
