Itching after the use of diazotide suppositories when there is no itching in the vagina is clinically caused by the following reasons: first, allergy to the drug, which causes congestion and edema in the vaginal mucosa and severe itching due to allergy to diazotide suppositories. If the primary disease is treated, the treatment can be continued with other drugs. Secondly, during the use of diazotide suppositories, no attention is paid to hygiene, so that pathogenic bacteria are brought into the vagina. The most common clinical condition is that Candida albicans multiply after being brought into the vagina, so that local itching occurs and a large amount of tofu-like vaginal discharge appears. It is recommended to have a routine laboratory test of the white belt and then give treatment according to the results.
