Kyleena, a progestin intrauterine system, is used for contraception and related menstrual management.

- Prevention of pregnancy: provides highly effective, long‑acting reversible contraception for up to five years. - Long‑acting reversible contraception: offers a convenient, hormone‑based method that does not require daily dosing. - Reduction of menstrual bleeding: may lessen menstrual blood loss and dysmenorrhea in some users.

Common Side Effects: - Irregular bleeding or spotting: unpredictable bleeding patterns, especially during the first months. - Pelvic pain or cramping: discomfort around the insertion site. - Headache: mild to moderate tension‑type headaches. - Breast tenderness: transient sensitivity or swelling.

Serious or Rare Side Effects: - Uterine perforation: rare injury to the uterine wall during insertion. - Pelvic infection: signs include fever, foul discharge, or severe pain. - Expulsion of the device: the IUS may be partially or fully expelled, reducing efficacy.

Before insertion, several safety steps should be observed.

- Confirm non‑pregnancy: verify the patient is not pregnant prior to placement. - Assess uterine anatomy: ensure appropriate uterine size and orientation for device fit. - Screen for active infection: avoid insertion in the presence of pelvic or cervical infection. - Counsel on bleeding changes: inform patients about possible irregular bleeding patterns. - Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Levonorgestrel released from Kyleena may interact with systemic medications that affect hormone metabolism.

Major Interactions (Avoid): - Rifampin and other strong enzyme inducers: may lower levonorgestrel levels and reduce efficacy. - Anticonvulsants such as carbamazepine or phenytoin: can increase hormone metabolism. - Antiretroviral drugs like efavirenz: may diminish contraceptive effectiveness.

Moderate Interactions (Monitor Closely): - Certain antibiotics (e.g., tetracycline): slight reduction in hormone activity, monitor bleeding. - Herbal supplements such as St. John’s wort: may induce hepatic enzymes, observe for breakthrough bleeding. - Hormonal therapies (e.g., combined oral contraceptives): generally safe but may be unnecessary when using Kyleena.
