The main ingredient of Dacrynic is miconazole, which is a broad-spectrum antifungal drug with good fungicidal effect on Candida, so it is mainly used for the treatment of superficial fungal infections, like ringworm, ringworm, ringworm, lichen planus, nail fungus, and diaper rash. It is more effective when applied directly to the affected area, but the affected area should be washed and dried before applying the ointment. In order to avoid recurrence you need to use it continuously, and after the symptoms disappear you also need to use it continuously for at least one week, avoiding contact with the eyes, mouth, nose and other mucous membrane areas. In order to avoid repeated infections it is necessary to pay attention to personal hygiene and to isolate from family members. Side effects such as rash, itching and burning sensation may occur after using the medication and can be relieved by washing the medication away.
