Lamisil’s Introduction
Understanding Lamisil
An antifungal medication known as Lamisil, or terbinafine by its generic name, is frequently used for the treatment of fungal infections. It is effective in treating fungal infections such as athlete’s foot, ringworm, and fungal nail infections by inhibiting the growth of fungi.
FDA Approval and History
The FDA approved the medication Lamisil in 1996 for skin infections. Since then, it has been one of the common oral and topical treatment options for a variety of fungal infections, and continues to provide relief to many patients in a timely manner.
Lamisil’s Applications
Primary Uses for Fungal Infections

Ringworm (Tinea corporis)
Jock itch (Tinea cruris)
Fungal nail infections (Onychomycosis).
In regards to treatment, Lamisil can be used in a topical form (cream, spray, or gel) or in an oral tablet form based on the infection’s severity level.

How Lamisil Works
The Role of Terbinafine
Lamisil contains the active ingredient, terbinafine which works by targeting ergosterol, which is important in the composition of fungal cell membranes. By impairing the synthesis of ergosterol, terbinafine membrane, destroys the fungal cell and thus causes the cell to die.
How Lamisil Targets Fungal Cells
In contrast to other antifungal treatments, which focus mainly on the cell wall or other components, Lamisil’s membrane targeting action gives it systemic activity against a large variety of fungi and makes it a strong systemic treatment.
Forms and Dosage of Lamisil
Oral vs Topical Treatment
