The yellowish green color of the leucorrhoea after the use of povidon suppositories by the patient suggests two possibilities: first, the normal leucorrhoea is mixed with the drug in the residue and formed by the povidon suppositories, which under normal circumstances can be milky white or yellowish. After a woman has been treated with a pessary, it is unlikely that the pessary will be fully absorbed and there will be drug residue present, so the vaginal leucorrhea and mucus can be yellowish-green. Patients can choose to use bitter ginseng lotion or use water to flush out the excessive vaginal residue before putting the medicine. Secondly, if the patient has yellow-green leucorrhea after using the medicine, it proves that the infection still exists or the treatment is delayed due to improper treatment, and the yellow-green leucorrhea appears due to the aggravation of its infection, and the leucorrhea will be extraordinarily large and smelly, so the patient needs to stop using the Povidone pessary and switch to other medicines for treatment.
