Vaginal medication should not be used during menstruation because it will be washed out by menstrual blood during menstruation and will not be effective in treating mycotic vaginitis. Since menstrual blood is alkaline, the alkaline environment of the vagina during menstruation will inhibit the growth of mycobacteria. During menstruation, mycosis can be treated with oral medication such as fluconazole tablets or mycoplasma tablets. You can also wash your vulva with lotion during menstruation to keep it clean and hygienic, and continue vaginal medication for mycosis after menstruation. Mycosis vaginalis is prone to recurrence, so it is important to have a routine review of the leucorrhoea after treatment to understand how the vaginitis is being treated and to consolidate the treatment for a course if necessary.
