Levosert Single-Handed Inserter (Levonorgestrel)

• Levosert Single-Handed Inserter, containing levonorgestrel, acts within the hormonal contraceptive pathway to prevent pregnancy.
• Long‑acting reversible contraception: provides up to five years of highly effective pregnancy protection.
• Prevention of unintended pregnancy: reduces the risk of conception for women of reproductive age.
• Management of heavy menstrual bleeding: can lessen menstrual blood loss and improve cycle regularity.

• Levonorgestrel released from the intrauterine system binds to progesterone receptors in the endometrium, cervical mucus and hypothalamic‑pituitary axis. This progestogenic activity thickens cervical mucus, suppresses ovulation in some cycles, and induces endometrial atrophy, creating an environment that prevents sperm penetration and implantation.

Levosert may be associated with a range of adverse reactions, most of which are related to the intrauterine device and local hormone exposure.

Common Side Effects

• Irregular vaginal bleeding or spotting
• Amenorrhea (absence of periods) after initial months
• Pelvic or cramping pain at insertion
• Discomfort or soreness at the insertion site

Serious or Rare Side Effects

• Uterine perforation during insertion
• Expulsion of the intrauterine system
• Pelvic inflammatory disease or infection
• Ectopic pregnancy if contraception fails

• Before prescribing Levosert, clinicians should consider several precautionary measures to ensure patient safety.
• Screen for contraindications: confirm absence of active pelvic infection, uterine anomalies, or current pregnancy.
• Assess thromboembolic risk: avoid in women with a history of clotting disorders unless benefits outweigh risks.
• Monitor bleeding patterns: counsel patients about possible changes in menstrual flow after insertion.
• Verify device position: schedule follow‑up examination if abnormal symptoms such as pain or missing strings occur.
• Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Levosert can interact with other medicines that affect hormone metabolism or uterine environment.

Major Interactions (Avoid)

• Enzyme‑inducing anticonvulsants (e.g., carbamazepine, phenytoin): may markedly reduce levonorgestrel levels and contraceptive efficacy.
• Rifampicin or rifampin‑containing regimens: can lower hormone concentrations, increasing risk of unintended pregnancy.

Moderate Interactions (Monitor Closely)

• Antibiotics such as tetracycline: may slightly diminish hormonal effect; advise additional contraceptive method.
• Azole antifungals (e.g., ketoconazole): may increase levonorgestrel exposure, potentially enhancing side effects.
• Herbal supplements like St. John’s wort: can accelerate hormone metabolism, reducing effectiveness.
