- Long‑acting reversible contraception: provides up to five years of highly effective pregnancy prevention for women of reproductive age. - Prevention of unintended pregnancy: offers a reliable, low‑maintenance option for women seeking to avoid conception. - Management of heavy menstrual bleeding: can reduce the volume and duration of menstrual bleeding in some users. - Non‑daily contraceptive method: delivers continuous hormone release, eliminating the need for daily pills or frequent dosing.

Kyleena may be associated with a range of adverse reactions, which are generally categorized by frequency.

Common Side Effects: - Irregular bleeding: spotting or changes in menstrual pattern. - Amenorrhea: absence of periods. - Pelvic pain: discomfort after insertion. - Cramping: uterine cramps during the first cycles. - Headache: mild to moderate. - Breast tenderness: mild soreness or swelling.

Serious or Rare Side Effects: - Uterine perforation: rare injury during insertion. - Expulsion: device may be expelled from the uterus. - Infection: pelvic inflammatory disease or severe infection.

Prior to insertion and during use, several precautions should be observed to ensure safety and effectiveness.

- Screen for pregnancy: confirm the patient is not pregnant before insertion. - Assess uterine anatomy: avoid in women with uterine anomalies or fibroids that distort the cavity. - Check for active infection: contraindicated in the presence of pelvic or cervical infection. - Hormone sensitivity: do not use in individuals with known levonorgestrel hypersensitivity. - Contraindicated conditions: avoid in women with breast cancer or other hormone‑dependent malignancies. - Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Levonorgestrel may interact with other medicines, influencing its contraceptive efficacy.

Major Interactions (Avoid): - Enzyme inducers (e.g., rifampin, carbamazepine): may reduce levonorgestrel effectiveness. - Antifungal azoles (e.g., ketoconazole): may increase systemic levonorgestrel exposure. - Protease inhibitors (e.g., ritonavir): potential alteration of hormone levels.

Moderate Interactions (Monitor Closely): - Certain antibiotics (e.g., tetracycline): may slightly affect contraceptive reliability. - Herbal supplements (e.g., St. John’s wort): may reduce hormonal efficacy.
