Ganciclovir can be used to treat shingles, which can be treated with an IV ganciclovir injection and topical ganciclovir ointment. Herpes zoster is mainly caused by varicella-zoster virus infection due to excessive late nights, mental tension, stress, heavy alcohol consumption, suffering from severe diabetes and other medical conditions. Along with the above treatment, the antiviral treatment can be enhanced by combining with vaxilovir hydrochloride pellets 0.3 grams taken orally twice daily. Oral methylcobalamin capsules, one capsule three times a day, are also required to nourish the nerves. Oral pidomod oral solution, thymidine enteric capsule and splenamine-freeze dried powder are taken to improve the immune ability of the body. If the pain is more intense, the patient can also apply capsaicin ointment topically to enhance the pain-relieving effect.
