Levosertone

Levonorgestrel, the active ingredient in Levosertone, is a progestin presented as an intrauterine system for intrauterine use. It provides long‑acting reversible contraception for women of reproductive age.

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

Levosertone (levonorgestrel) is a hormonal contraceptive that works within the reproductive system.

- Contraception: provides continuous birth control for women seeking reliable intrauterine contraception. - Heavy menstrual bleeding: reduces menstrual blood loss and improves cycle regularity. - Endometrial protection: offers protection against endometrial hyperplasia when combined with estrogen therapy.

Levosertone may cause a range of adverse reactions, most of which are related to its local hormonal activity.

Common Side Effects: - Irregular bleeding or spotting - Amenorrhea (absence of periods) - Pelvic or abdominal cramping - Dysmenorrhea (painful periods) - Headache - Breast tenderness

Serious or Rare Side Effects: - Uterine perforation during insertion - Device expulsion or migration - Pelvic inflammatory infection - Ectopic pregnancy if contraception fails - Severe allergic reaction (rash, swelling) - Thromboembolic events (deep vein thrombosis, pulmonary embolism)

Before using Levosertone, certain safety considerations should be observed.

- Pregnancy contraindication: do not insert in pregnant women. - Breastfeeding: discuss risks with a healthcare professional. - Pelvic infection: avoid insertion during active pelvic inflammatory disease. - Uterine anomalies: assess for fibroids or malformations that may affect placement. - Follow‑up: schedule post‑insertion check to confirm correct positioning. - Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Levosertone can interact with other medicines that affect hormone metabolism.

Major Interactions (Avoid): - Rifampin, carbamazepine, phenytoin, phenobarbital: potent enzyme inducers that markedly reduce levonorgestrel levels. - St. John’s wort: herbal inducer that may compromise contraceptive efficacy.

Moderate Interactions (Monitor Closely): - Ketoconazole, itraconazole: antifungals that can increase levonorgestrel concentrations. - Efavirenz, nevirapine: antiretrovirals that may lower effectiveness. - Certain antibiotics (e.g., griseofulvin): may modestly affect hormone levels. - Anticonvulsants (e.g., valproate): require monitoring of contraceptive reliability.
