Burning pain in the hemithorax, band-like vesicles following a dermatome… a classic picture of herpes zoster. In this video, Dr. Eric Rulle presents a practical and updated guide for physicians and academics: when to start antiviral therapy, how to manage pain, what warning signs require hospitalization, and when to refer to specialists. Objective: to reduce complications, speed up recovery, and standardize daily prescriptions. You will learn (practical checklist): ✔ Clinical recognition: painful prodrome 1–3 days and unilateral dermatomeric vesicular eruption. ✔ Red flags that change management: extensive dissemination, ocular involvement, otological involvement (Ramsay Hunt syndrome), signs of encephalitis or meningism, immunosuppression. ✔ Antiviral in the acute phase:  • Acyclovir 800 mg every 4 hours (5 doses daily; skip the nighttime dose).  • Valacyclovir 1 g every 8 hours.  • Famciclovir 500 mg every 8 hours.  • Typical duration: 5–7 days or until complete crusting. ✔ When to hospitalize and use IV acyclovir: extensive disease, immunosuppressed patients, ocular or neurological involvement. ✔ Stepwise analgesia:  • 1st step: dipyrone or paracetamol ± anti-inflammatory, if without contraindications.  • 2nd step: weak opioid (codeine or tramadol) if persistent pain.  • Selected adjuvants: lidocaine patch for localized pain; avoid routine gabapentin in the acute phase. ✔ Corticosteroids: pros and cons in the acute phase; not proven to reduce post-herpetic neuralgia. ✔ Essential guidelines: care for lesions, contact isolation while active vesicles are present, avoid contact with pregnant women and immunocompromised individuals, immediate return if worsening occurs. ✔ Follow-up: when to consider specific management of post-herpetic neuropathic pain and vaccination updates. ➡️ Subscribe to the channel, activate the bell and leave your like to receive objective content on clinical practice and emergency care.
