Dacrynic suppositories are usually best used for 7 days. This is because Dakine suppositories are for the treatment of mycosis fungoides, which is a fungal infection. Mycosis vaginalis is more prone to recurrence and a course of treatment lasts for 7-10 days. In general, mycosis vaginalis should be treated with 1-2 courses of medication, that is, about 3 days after each menstrual period, with or without symptoms for 7-10 days to form a course of treatment, otherwise it may cause easy recurrence. It is forbidden to have intercourse during the use of Dacronin suppositories, and you should pay attention to your personal hygiene during normal times. The underwear should be scalded with boiling water and exposed to the sun. At the same time, if there are conditions, you can boil the panties in water for 3-5 minutes, which can play a sterilizing effect to avoid re-infection of fungi. It is also important to pay attention to the hygiene of intercourse, before and after intercourse, it is best to wash the vulva and genitals with lotion, so as to avoid cross-infection. Avoid eating spicy and stimulating foods to avoid the recurrence of mycosis vaginalis.
