Brief Answer:
it is not used

Detailed Answer:
Hi,
Thanks for writing to us.
Herpes zoster is not treated with hydrogen peroxide.
Herpes zoster is treated with oral antiviral like acyclovir or valcyclovir or famciclovir.
We also prescribe oral antibiotics to prevent develoment of any superceding infection. If associated with pain, we prescribe anagesics too. Topical antibiotic or calamine lotion should be used to heal and soothe the lesion.
Please tell me about the exact manifestation that you are having now like
Site and extent of lesion.
Since how long are you having it
If the lesions have crusted or have developed pus formation.
Associated features like pain or itching or burning sensation

If possible please upload an image of the affected area as that would help me in further clarification. I would never prescribe hydrogen peroxide for zoster lesions
