Introduction
In general, preferred medications for herpes zoster include acyclovir cream, compound neomycin ointment, compound lidocaine cream, penciclovir cream, and foscarnet sodium cream. However, it is important to consult a qualified physician before using any medication. Additionally, recombinant human interferon α2b gel may also be considered. If discomfort occurs, seek medical attention at a hospital promptly.
In general, preferred medications for herpes zoster include acyclovir cream, compound neomycin ointment, compound lidocaine cream, penciclovir cream, and foscarnet sodium cream. However, it is important to consult a qualified physician before using any medication. Specific details are as follows:
1. Acyclovir Cream
Herpes zoster neuralgia is caused by viral infection. Topical application of acyclovir has antiviral effects that can relieve patients' neuralgia symptoms and effectively inhibit both herpes simplex virus and varicella-zoster virus.
2. Compound Neomycin Ointment
After the blister walls of herpes zoster rupture, compound neomycin ointment can be applied externally. This medication has strong antibacterial properties, helping prevent bacterial infections at sites affected by herpes zoster neuralgia and avoiding further pain aggravation due to secondary infection.
3. Compound Lidocaine Cream
This medication is a local anesthetic that reduces pain through numbing action. Its mechanism involves lidocaine blocking voltage-gated sodium channels, thereby producing analgesic effects. Blocking these sodium channels reduces ectopic discharges and subsequently inhibits peripheral sensitization.
4. Penciclovir Cream
The main active ingredient is penciclovir, a nucleoside antiviral agent that selectively inhibits the synthesis and replication of herpesvirus DNA, making it suitable for treating herpes zoster.
5. Foscarnet Sodium Cream
The primary component is foscarnet sodium, an antiviral agent that inhibits viral replication. It can be used in the treatment of herpes zoster induced by impaired immune function.
In addition, recombinant human interferon α2b gel may also be considered. If discomfort occurs, seek medical attention promptly to avoid delaying treatment.
