If herpes zoster appears around the mouth, it is also recommended to give antiviral medication, which can be given as vaxilovir, famciclovir or acyclovir, orally for 7-10 days. It is recommended to give oral medication within 7 days of the appearance of blisters, and if the blisters have been present for more than 7 days, it is not recommended to take oral antiviral medication, as the virus is no longer replicating and there is no point in taking oral antiviral medication. At the same time, oral antiviral medication within 3 days of the appearance of blisters is the best treatment effect. In addition to oral antiviral drugs, it is recommended to take nerve-nourishing vitamin B and vitamin E orally, and to use topical penciclovir gel or povidone-iodine solution topically. If the pain is obvious you can take oral painkillers, and for combined bacterial infections you can also give antibiotic co-treatment. Be sure to avoid strain, adjust sleep, to avoid the decline of resistance. Those who are able to do so can also go to a regular hospital for physical therapy to relieve pain.
