Uses of undefined

Terbinafine is an antifungal medication primarily used to treat dermatophyte infections, such as tinea corporis, tinea cruris, tinea pedis, and onychomycosis. It is effective in treating superficial fungal infections of the skin, nails, and hair by targeting the underlying fungal cause. Additionally, terbinafine is utilised for the treatment of onychomycosis, a fungal nail infection that is notoriously difficult to treat. It also serves as an alternative treatment for dermatophyte-induced infections in immunocompromised patients, offering relief when other therapies fail.

undefined Drug administaration and Dosage available

Take terbinafine with or without food. If taking the oral form, swallow the tablet whole with a glass of water. Avoid crushing, chewing, or breaking the tablet. Adhere to the prescribed dosage and duration of treatment. For onychomycosis, therapy may last several months due to slow nail regrowth.
