Levosert Shi

Levonorgestrel, the active ingredient in Levosert Shi, is a progestin presented as an intrauterine system for intrauterine use. It delivers a continuous low dose of hormone to prevent ovulation, thicken cervical mucus, and alter the endometrium, providing reliable, long‑acting reversible contraception for women of reproductive age.

Levosert Shi, a levonorgestrel intrauterine system, is used within the hormonal contraceptive pathway for preventing unintended pregnancy.

- Long‑acting reversible contraception: provides up to five years of pregnancy prevention without daily dosing. - Prevention of unintended pregnancy: offers a highly effective method for women of reproductive age. - Intrauterine contraception preference: suitable for women who choose a non‑oral, device‑based birth control option.

Levosert Shi 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. - Cramping during or after insertion. - Breast tenderness. - Headache.

Serious or Rare Side Effects: - Uterine perforation during insertion. - Expulsion of the intrauterine system. - Pelvic inflammatory disease or infection. - Ectopic pregnancy if contraception fails. - Allergic reaction to device materials. - Severe abdominal pain requiring medical evaluation.

Before using Levosert Shi, certain precautions should be observed to ensure safety and effectiveness.

- Screen for contraindications: ensure the patient has no active pelvic infection, unexplained vaginal bleeding, or uterine anomalies. - Confirm non‑pregnancy: verify the patient is not pregnant prior to insertion. - Timing of insertion: place the device within the first seven days of the menstrual cycle for optimal efficacy. - Follow‑up assessment: schedule a check‑up six weeks after insertion to confirm correct positioning. - Plan for removal: arrange device removal after the approved duration or earlier if complications arise. - Store at ambient temperature: keep in the original packaging, protect from moisture and direct sunlight.

Levosert Shi may interact with other medicines that affect hormone metabolism or efficacy.

Major Interactions (Avoid): - Enzyme‑inducing anticonvulsants (e.g., carbamazepine, phenytoin): may reduce levonorgestrel levels. - Rifampin or other strong enzyme inducers: can lower hormonal effectiveness. - Certain antiretroviral protease inhibitors: may alter hormone metabolism.

Moderate Interactions (Monitor Closely): - Broad‑spectrum antibiotics (e.g., tetracycline): may slightly diminish contraceptive efficacy. - Herbal supplements such as St. John’s wort: could reduce hormone levels and increase risk of breakthrough bleeding.
