Gray nails are mainly treated with oral antifungal drugs, which can be supplemented with topical antifungal drugs. For gray nails with ineffective drug treatment, surgical nail extraction can be performed. 1. Oral antifungal drugs: such as itraconazole, terbinafine, etc. Liver function should be monitored regularly during the medication. Oral antifungal drugs need to be used in sufficient quantity and on a full course of treatment, if you stop taking the drugs at will, it may lead to recurrence of the disease. Specifically under the guidance of a doctor to standardize the use of drugs. 2. Topical medication: Topical antifungal medication, such as amorphophallus application, cyclopentanone application, etc., can be used as prescribed by the doctor, which can be used to assist in the treatment of gray nails. 3. Surgical treatment: For those who still have recurrent gray nails despite standardized and sufficient medication, surgical nail extraction can be considered. When gray nails appear, you should consult a doctor in time.
