Jaydess (Levonorgestrel)

• Jaydess is a hormonal intrauterine system that acts on the reproductive endocrine pathway to provide contraception and manage menstrual disorders.
• Contraception: offers highly effective, reversible birth control for up to three years.
• Heavy menstrual bleeding: reduces menstrual blood loss and improves bleeding patterns.
• Endometrial protection: maintains a thin, stable endometrium, decreasing the risk of hyperplasia.

• Levonorgestrel released from the intrauterine system binds to progesterone receptors in the cervical mucus, endometrium, and hypothalamic‑pituitary axis. This thickens cervical mucus, inhibits endometrial proliferation, and suppresses ovulation, creating a local environment that prevents sperm penetration and implantation, thereby averting pregnancy.

Jaydess 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 discomfort
• Headache or breast tenderness
• Mood changes or acne
• Weight gain or fluid retention

Serious or Rare Side Effects

• Uterine perforation during insertion
• Device expulsion or displacement
• Pelvic inflammatory infection
• Ectopic pregnancy if contraception fails
• Severe allergic reaction (anaphylaxis)
• Hormone‑dependent tumor growth (rare)

• Before prescribing Jaydess, clinicians should consider several safety measures.
• Screen for pregnancy: product is contraindicated in confirmed or suspected pregnancy (Category X).
• Assess uterine position: ensure appropriate placement and uterine size.
• Monitor for infection: watch for signs of pelvic infection after insertion.
• Check for uterine abnormalities: avoid in bicornuate or septate uterus.
• Store at room temperature: keep in original packaging, protect from moisture and direct sunlight.

Levonorgestrel released from an intrauterine system can be affected by certain medications that alter hormone metabolism.

Major Interactions (Avoid)

• Rifampin or other strong enzyme inducers: may reduce levonorgestrel effectiveness.
• Certain antiepileptic drugs (e.g., carbamazepine, phenytoin): can lower hormone levels.
• St. John's wort: may decrease contraceptive efficacy.

Moderate Interactions (Monitor Closely)

• Antiretroviral agents (e.g., efavirenz): may modestly reduce hormone exposure.
• Antifungal azoles (e.g., ketoconazole): could increase levonorgestrel levels.
• Herbal supplements affecting CYP3A4: monitor for breakthrough bleeding.
