After the blisters of herpes zoster have dried up and the blisters and vesicles have developed scabs, you can ask your medical professional and choose to stop applying the ointment according to your personal situation. If the blisters and vesicles are crusted over, the inflammation caused by the herpes zoster virus has been better controlled, and you can stop using antiviral medication under your doctor’s supervision. However, it should be noted that herpes zoster lesions have not been completely repaired when they are crusted over, so you can continue to apply antibiotic ointment to prevent secondary infections. Herpes zoster medication needs to follow the doctor’s instructions, to avoid blindly use or unauthorized discontinuation of medication, resulting in adverse reactions or delayed condition leading to aggravation of the symptoms, resulting in adverse effects, so the specific discontinuation of medication need to be under the guidance of a professional doctor combined with the individual situation and the development of the disease to judge.
