Red Nucleus Lotion is a topical solution that needs to be washed and dried before use. Take 10ml of the solution, add 90ml of warm water and shake it well, then use the diluted solution to rinse the vagina and vulva twice a day for 7 days. However, before using Red Nucleus Lotion, you should observe whether there is any change in the properties of the lotion and stop using it if you find any precipitate. If patients experience discomfort after using Red Nucleus Lotion, such as vaginal and vulvar itching, vulvar rash, etc., it is possible that the patient may have an allergic reaction, so it is necessary to stop using it in time. If the symptoms of vaginitis or cervicitis do not improve after 1 week of using Red Nucleus Lotion, you need to seek medical treatment in time to avoid delaying the treatment of the disease.
