A regimen of treatment for vaginitis combining the use of a povidone-iodine solution for swabbing, a povidone-iodine vaginal gel for application at night and a povidone-iodine douche for use in the morning, was evaluated in 93 courses of treatment in 87 patients with monilial or trichomonal vaginitis or a combination of both. In monilial vaginitis, symptoms were cleared and negative laboratory results obtained in one to three weeks in all 74 courses of treatment. These results were obtained within one week in 52 cases and within two weeks in another 17. In four of five patients with trichomonal vaginitis, symptoms were cleared within three weeks. In the fifth, negative laboratory results were obtained but a mild discharge persisted at the end of the fourth week. In 14 courses for combined infections, symptoms were cleared within three weeks in 13, and the pathogens were absent in those patients within four weeks. In one patient the disease did not respond.
