Vaginal pessary is a topical medication for the treatment of vaginitis or cervicitis. When the medication is placed directly deep into the vagina, it dissolves in the vagina and then exerts its effect to kill the local bacteria or fungus directly, which facilitates the treatment of inflammation. After the oral medication is absorbed, the final concentration that reaches the vagina is very low and slow. There are many kinds of vaginal suppositories such as Dacrynic, Metronidazole, Diazotide, and Povidone-based suppositories, and different suppositories treat different diseases. For example, metronidazole suppositories are for trichomoniasis, dacrynic suppositories are for mycosis fungoides, diazotide suppositories are for mixed vaginitis, and povidone suppositories are for cervicitis. When using vaginal suppositories, you need to have a routine leucorrhoea examination to determine what inflammation it is before you can use the right medicine for the disease, if you use the suppositories improperly, it is easy to aggravate the disease.
