Shingles and Chickenpox (Varicella-Zoster Virus) - Treatment for an Acute Shingles Attack

(Page 3)

Oral Corticosteroids

Oral corticosteroids, including prednisolone or prednisone, are powerful anti-inflammatory medications. They have some benefit for reducing pain and accelerating healing in acute attacks when used with acyclovir. (They are not recommended without acyclovir.) They also may be helpful for improving symptoms of Bell's palsy and Ramsay Hunt syndrome. Corticosteroids do not appear to prevent a further shingles attack or reduce the risk for PHN. Side effects of corticosteroids can be severe, and patients should take oral steroids at as low a dose and for as short a time as possible. (Injected or intravenous steroids, however, may offer specific relief for PHN without significant side effects.)

Epidural Blocks

Epidural blocks are injections of local anesthetics and steroids outside the tough membrane surrounding the spinal cord (the dura matter). The injected drugs block the nerves and may offer relief from acute herpes zoster pain for some people. A 2006 study found that a single epidural injection helps slightly to relieve shingles pain for a month, but the effect does not last any longer. The injection does not help prevent postherpetic neuralgia.
