Patients with shingles who have scabs generally do not need to take antiviral medication because shingles is about 7-10 days old if all the scabs have formed. At this time the basic virus has been killed and there is no need to take oral antiviral drugs. However, for nerve-nourishing drugs, such as methylcobalamin capsules, it is still necessary to take further oral medication, and you can even inject adenosine cobalamin injection to further nerve-nourishment. If you still have pain after scabbing, you can use topical capsaicin ointment and take oral pregabalin capsules, gabapentin capsules, and Anlao small skin umbrella tablets. Patients with shingles should pay attention to good rest and sleep. Although they are close to scabbing, they should avoid straining and excessive anger, and avoid spicy and stimulating diets, such as raw onion, raw garlic, etc.
