Herpes under the nose is a very common form of orofacial herpes, which is an inflammatory skin reaction caused by herpes simplex virus infection. Patients can be treated orally with antiviral drugs such as acyclovir, valacyclovir and famciclovir, one of these three drugs can be taken. If it is the patient’s first time to appear, the disease can be effectively controlled after seven to ten days of oral administration, and the patient can apply acyclovir ointment or penciclovir ointment topically at the same time. If there is no significant local ulceration, you can also apply some topical stove glycerine lotion, but if there is significant local ulceration, stove glycerine lotion can not be applied. In the treatment at the same time patients must try to improve their own immune resistance, because the disease is self-limiting but easy to recur.
