First, oral medication, that is, systemic therapy, is an important method to treat onychomycosis. Most adults need systematic oral medication to completely cure onychomycosis. Terbinafine and itraconazole are the most commonly used systemic drugs. There was a misunderstanding in the past that these two drugs were more powerful in treating onychomycosis and hurt the liver, so people didn't want to use them. In fact, a large sample study of these two drugs shows that their liver damage is not serious, and it is not more serious than the antibiotics that are often used at ordinary times. If there is no liver disease before and there is no problem of elevated transaminase, you can take medicine completely. Of course, the interaction between drugs should also be considered when taking drugs, because different drugs can be metabolized from the liver, and it may have interactions. If you want to decide to take medicine orally, you must go to the hospital and ask the doctor to prescribe medicine.
Second, in addition to systemic oral drugs, there are also external drugs, and external drugs are mainly adjuvant therapy. For some special people, such as children, pregnant women or lactating women, if treatment is needed, oral administration is not recommended, and external use should be given priority. There is a commodity nail polish called Amorofen liniment, which is a kind of nail polish. Can be applied to nail surface, once a week 1-2 times. For less severe onychomycosis or people who grow faster directly, the effect is ok, but the cure rate is not as good as that of systematic oral medication.
Third, in addition to external use and oral drugs, there is another method called physical therapy, which is chemical nail removal. Manicure and chemical nail removal belong to physical therapy, while laser therapy belongs to physical therapy and is also an auxiliary treatment method. You can trim off a broken nail or put a laser on a broken nail, which has an inhibitory effect on fungi, but it is also an adjuvant treatment. Comprehensive judgment is needed to select one or more suitable methods according to the severity of patients' nails.
