It is normal to have a bed full of water with interferon. This is because the interferon will gradually dissolve after the vaginal drug, so some of the interferon liquid will flow from the vagina, so in the case of the application of interferon, it is best to pad or light sanitary napkins to avoid contamination of bed sheets or underwear. The effect of interferon in the treatment of HPV is good for three months to six months. After three months of medication, stopping the medication for half a month, it is necessary to go to the hospital to review whether the HPV virus has disappeared. If it has disappeared, continue to regularly recheck the HPV virus can. If it still exists, you need to continue to use the medicine for three months, and basically the virus will disappear in six months.
