Can you apply Fungi-Nail to fingernails?
Fungi-Nail is designed for treating fungal infections of nails. Since fingernails are also nails, it can be used on fingernails when the problem involves a fungal nail infection.
What kind of fungal nail problem should it be used for?
It’s intended for nail fungus (onychomycosis), which can affect both toenails and fingernails. If your fingernail changes match a fungal infection (for example, thickening, discoloration, or crumbling), Fungi-Nail is typically used for that purpose.
When to use it vs. when to avoid it
Use it on fingernails only as directed by the product label (including how often to apply). Avoid getting it on surrounding skin in ways the label discourages, and stop and seek medical advice if you get significant irritation.
When you should see a clinician instead
If the fingernail involvement is severe, spreading to multiple nails, painful, or not improving after several weeks of treatment, a clinician can confirm the diagnosis and consider other treatments.
