How Herpes Zoster Ophthalmicus Medications Work

Herpes Zoster Ophthalmicus (HZO) is a viral infection caused by the reactivation of Varicella-Zoster virus, which can lead to severe ocular symptoms. The gold standard medication for treating HZO is Acyclovir, an antiviral drug that works by inhibiting viral DNA synthesis and replication.

• Acyclovir Mechanism of Action:
• Inhibits viral DNA polymerase, preventing viral replication
• Interferes with viral transcription and translation

Alternatives to Acyclovir include Valacyclovir and Famciclovir, which are also antiviral medications that work by inhibiting viral DNA synthesis and replication. In addition, pain management with opioids or NSAIDs may be necessary to alleviate severe ocular pain associated with HZO.

Pain Management: Opioids (e.g., morphine) or NSAIDs (e.g., ibuprofen) can help manage severe ocular pain associated with HZO. These medications work by binding to opioid receptors in the brain, reducing pain perception, or inhibiting prostaglandin synthesis, respectively.
