Terbinafine, when combined with fluconazole, has occasionally been successful in treatment of oropharyngeal infections due to fluconazole-resistant Candida spp. It acts by inhibiting the enzyme, squalene oxidase which blocks the synthesis of bacterial and fungal cell walls thus preventing growth.
Terbinafine is mainly effective on a specific group of fungi, dermatophytes. Tinea cruris, tinea corporis, tinea pedis; onychomycosis due to dermatophytes; cutaneous candidiasis; tinea versicolor; active against Epidermophyton floccosum, Trichophyton mentagrophytes, Trichophyton rubrum. Terbinafine inhibits fungal sterol biosynthesis, causing accumulation of squalene within the fungal cell and cell death.
Adverse reactions to terbinafine are in general transient and mild. Take at regular intervals. Complete the prescribed course unless otherwise directed. Make sure you take this medicine regularly and complete the course as directed by your doctor. It is important to complete the course, even if your symptoms have cleared up, otherwise there is a risk of the infection returning.
Terbinafine is a prescription drug that comes in 250 mg tablets. It is available on prescription only as tablets for oral use, but the online pharmacy, will sell Terbinafine without prescription. You may be able to order Lamisil from them online and save the local pharmacy markup.
