Fingernail fungal infections can be treated with medications. Topical medications such as terbinafine cream and miconazole ointment work by inhibiting the reproduction of the fungus. For localized thickening of nails, a nail scraper can be used to remove the excessively thick surface of the nail before applying the cream. Topical medications are often used as adjunctive treatments and are not easily cured when used alone. Oral drugs: including itraconazole capsules, terbinafine tablets and other oral antifungal preparations, oral drug treatment course is longer, need to comply with the doctor’s instructions to use, can not stop without authorization. In addition, a very small number of patients who are not suitable for drug treatment and have abnormal liver function can choose physical therapy: such as laser therapy. Through its huge energy to kill, at the same time no obvious damage to normal tissue. But the clinical application is relatively small. For patients with fungal infections of finger nails, it is recommended that they go to regular hospitals as early as possible, and choose appropriate ways to actively treat under the guidance of doctors.
