Kyleena

Levonorgestrel, the active ingredient in Kyleena, is a progestin presented as a 13.5 mg intrauterine system for intrauterine use. It prevents pregnancy by acting locally within the uterus to thicken cervical mucus, inhibit sperm function, and alter the endometrium.

GNH USA supplies Kyleena as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Kyleena, a hormonal contraceptive delivered via an intrauterine system, is indicated for the prevention of pregnancy.

- Prevention of pregnancy: provides long‑acting reversible contraception for up to five years.

Kyleena may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects: - Irregular vaginal bleeding or spotting - Amenorrhea (absence of periods) - Pelvic or abdominal pain - Headache - Breast tenderness - Mood changes

Serious or Rare Side Effects: - Uterine perforation during insertion - Expulsion of the device - Severe pelvic infection (e.g., tubo‑ovarian abscess) - Ectopic pregnancy if contraception fails - Allergic reaction (rash, swelling, anaphylaxis)

Prior to insertion and during use, several safety considerations should be observed.

- Confirm non‑pregnancy: verify the patient is not pregnant before insertion. - Screen for uterine abnormalities: assess for fibroids, septa, or other malformations. - Evaluate for active pelvic infection: postpone insertion if infection is present. - Review concomitant medications: consider drugs that may reduce efficacy. - Provide follow‑up counseling: schedule post‑insertion check and advise on signs of complications. - Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Levonorgestrel released from Kyleena can be affected by other medicines.

Major Interactions (Avoid): - Enzyme inducers (e.g., rifampin, carbamazepine, phenytoin): may markedly reduce levonorgestrel levels. - Antiretroviral drugs (e.g., efavirenz): can decrease contraceptive effectiveness.

Moderate Interactions (Monitor Closely): - Antifungal agents (e.g., ketoconazole, itraconazole): may increase levonorgestrel exposure. - St. John's wort: may modestly lower hormone concentrations. - Certain antibiotics (e.g., griseofulvin): potential modest reduction in efficacy.
