Topical treatment of inflammatory dermatophyte infections, including tinea pedis (athlete's foot), tinea corporis (ringworm), tinea cruris (jock itch), and other inflammatory fungal skin conditions where both antifungal action and anti-inflammatory effects are needed.
Terbinafine works by inhibiting squalene epoxidase, an enzyme essential for fungal cell membrane synthesis, effectively killing the fungus. Betamethasone is a corticosteroid that reduces inflammation, itching, and associated discomfort by suppressing local immune responses and reducing inflammatory mediators in the skin.
For external use only; avoid contact with eyes, mouth, and mucous membranes. Should not be used on broken or ulcerated skin unless directed by a physician. Duration of treatment typically ranges from 1-2 weeks depending on the condition. Use only as prescribed; prolonged use of topical corticosteroids may cause skin thinning. Discontinue use and consult a healthcare provider if no improvement occurs after recommended treatment period or if irritation develops.
