Insertion, position checking and removal are performed by a trained healthcare professional. The user should attend the planned follow-up, know the recorded replacement date and seek assessment if the threads cannot be felt, the device is felt in the vagina, pregnancy is suspected or pelvic pain or fever develops.

Cramping, spotting, irregular bleeding, headache, acne, breast tenderness or ovarian cysts may occur, especially after insertion. Rare serious events include expulsion, uterine perforation, pelvic infection and ectopic pregnancy if pregnancy occurs. Seek medical or pharmaceutical advice if symptoms are severe, persistent or worsening.
