Hello, I can understand your concern. If, after starting the treatment, the itching has improved, then you had bacterial infection and Droxyl antibiotic worked to combat it. Other supportive treatments like vitamin tablets and Aquasoft Moisturizing cream will help in getting better skin over lips making them smooth and healthy. If you are taking good amounts of leafy vegetables and fruits, then you can discontinue the vitamin supplements after a month. However, if the itching has not improved, then you may need to consult the dermatologist again for investigations regarding possible viral infection, fungal infection or allergic reaction. I hope this information helps you. Thank you for choosing HealthcareMaic. Take care. Best, Dr. Viraj Shah
