Whether herpes zoster requires an infusion is usually determined by the condition. If the blisters are relatively mild, the blisters are relatively limited in extent, or the pain is not particularly obvious, the first treatment should be oral, plus topical medication or ultraviolet radiation, etc. Infusion therapy is usually not necessary. However, if the blisters are more extensive and even some bloody blisters appear. That is, if the blisters rupture and a vesicular surface appears, infusion therapy may be considered. If the pain is very severe in some patients, some infusion therapy can also be taken in order to relieve the pain. In the clinical infusion treatment is based on antiviral treatment drugs, usually divided into two treatments a day, every 12 hours for treatment, the infusion treatment time and oral time are the same, usually 7-10 days. In addition, if the patient’s gastrointestinal tract does not function well and cannot take oral medication, infusion therapy can also be taken at this time, but infusion therapy is not able to shorten the course of the disease, as there is a process for any kind of disease.
