Ornidazole suppositories can be inserted into the vagina, but Ornidazole tablets are not recommended to be inserted into the vagina. Ornidazole tablets, if inserted into the vagina, may cause irritation to the mucous membranes and may be difficult to melt, so they cannot exert the appropriate medicinal effect. Suppositories, on the other hand, melt easily in the vagina and are absorbed by the mucosal tissue for the purpose of treating the disease. Ornidazole is mainly used to treat vaginal inflammation caused by anaerobic infections, for example, bacterial vaginosis can be treated with Ornidazole suppositories. In addition, trichomoniasis can be treated with Ornidazole suppositories. If you are allergic to this drug, it should not be used and you should not have sexual intercourse during the vaginal plugging. It is recommended to stop the medication for 3-7 days after the clinical symptoms have completely disappeared and to go to the hospital to check whether the original pathogen has been cured.
