However, a systematic gynecological examination is needed before using the drug to clarify the indications and exclude contraindications. If there is only a simple displacement of the cervical columnar epithelium with no obvious inflammatory gynecological manifestations, no specific treatment is usually required.

For severe cervical inflammatory disease, cervical patch treatment has no significant effect and other treatment methods should be considered, and sexual intercourse is forbidden during cervical patch treatment and pubic cleanliness and hygiene should be maintained.
