The so-called snakebite is actually referred to as shingles in clinical practice. It is a common skin disease caused by varicella zoster virus infection. In clinical practice, herpes zoster is treated with antiviral therapy. Commonly used antiviral drugs, such as acyclovir, valaciclovir and famciclovir, are effective. However, it is emphasized that antiviral therapy should be applied early, in sufficient quantity and in sufficient courses. If available, it is best to start regular antiviral therapy within 72 hours of the onset of symptoms. Patients can take oral antiviral medications, and patients can also use topical medications, such as acyclovir ointment and penciclovir ointment, to apply antiviral medications externally. When the blisters are not broken, glycerin lotion can be applied externally. When the blister breaks, you can apply boric acid solution for wet compresses. When the local healing is relatively good, you can apply topical mupirocin. For patients with severe neuralgia, oral diclofenac and other non-steroidal anti-inflammatory drugs can be relieved.
