Everyone should be aware of this. Toenail fungus is not just a cosmetic concern, it's a progressive infection that gets worse without proper treatment. Most of the time, over-the-counter products fail, because they can’t penetrate most patients beneath the nail plate where the infection actually lives.
With numbers, everything is clear: oral terbinafine eliminates infection in 70–90% of cases, while topical-only treatments like Jublia report complete cure rates of just ~17–18% in clinical trials. That efficacy gap is exactly why prescription-grade, combination treatment exists.
Nail fungus happens beneath the nail plate, it is protected by three key barriers, the nail's keratin shield, fungal biofilm, and dormant spores that cause reinfection. What happens with surface-level treatments is they can't overcome these barriers alone, which is why infections recur.
Prescription treatment addresses this at two levels:
Remember, together, this top-down and bottom-up approach is what makes combination therapy the most clinically effective path forward.
STRIDE DUO™ is a dermatologist-developed combination treatment system clinically effective in 89% of cases. This is designed specifically to overcome the barriers that cause standalone treatments to fail.
It pairs oral terbinafine on a pulse dosing protocol (7 days on / ~90 days off) with STRIDE™ ClearNail Renewal™ topical. Pulse dosing works because terbinafine remains active in nail tissue for weeks after each cycle. This means the nail stays protected without daily dosing, and liver-related side effect risk is significantly reduced.
STRIDE™ ClearNail Renewal™ is formulated with four active ingredients for maximum penetration: Urea, Lactic Acid, Terbinafine, and DMSO.
