What is the treatment for shingles?


Antiviral medications (medications used to combat viral infections) are used against the varicella zoster virus. These medications help shorten the course of the illness and decrease the severity of the illness. They may also help prevent the potential complications sometimes encountered with shingles. They are most effective when started within 72 hours of the first appearance of the rash. There are several antiviral medications that can be used, including acyclovir (Zovirax), famciclovir (Famvir), and valacyclovir (Valtrex). In certain situations, intravenous (IV) antiviral medication may need to be administered.

Pain medication can be used to help relieve discomfort caused by the rash, which can sometimes be severe. For some individuals with mild pain, over-the-counter analgesics such as acetaminophen (Tylenol) or ibuprofen (Motrin or Advil) may be all that is needed. Individuals with more severe pain may require stronger opioid pain medication.


The use of corticosteroid medications, such as prednisone, is controversial in the treatment of shingles.
