Summary

Herpes zoster (HZ) is characterized by a painful dermatomal rash and significantly affects quality of life, with acute pain increasing the risk of postherpetic neuralgia. Although early antiviral therapy limits viral replication, its analgesic effect is insufficient, and many patients experience inadequate relief despite stepwise use of non-opioids and opioids. Recent attention has focused on the potential role of muscle relaxant, which can relieve skeletal muscle spasms and associated pain in acute musculoskeletal conditions. Therefore, investigators hypothesize that baclofen may effectively reduce the severity of HZ pain without significantly increasing adverse events.

Conditions

Then, based on the patient's response, the single dose can be gradually increased by 5mg each time, with a three-day interval. The maximum recommended dose is 30\~75mg daily. In addition, the group will contain conventional treatment for HZ, except baclofen, including NSAIDs, opioids, antiviral drugs and so on.
