The two are not mutually exclusive. Nowadays, most women have cervicitis. For women with acute cervicitis, oral antibiotics or anti-inflammatory drugs should be taken first, and then Mirena. For non-acute cervicitis, Mirena can be used. In addition, cervical erosion and cervicitis should be distinguished clearly. Cervical erosion is the outward migration of columnar cell epithelium and does not mean cervicitis. For women with cervical erosion, Mirena can be used.
