In clinical practice, the application of Povidon suppositories is based on the specific condition of the patient before the specific duration of use can be determined. The duration of treatment plus the consolidation course of treatment is about 14-21 days when using povidon suppositories for the treatment of mycosis fungoides. In the case of geriatric vaginitis, the specific duration of use of this medication is about 14 days. If the patient is suffering from obstetrical and gynecological diseases, he/she needs to go further to the obstetrics and gynecology department of the local public hospital for local laboratory examination of secretions and colposcopy to clarify which disease it is, and then choose the appropriate medication under the guidance of the doctor and follow the course of treatment.
