Microlut (Levonorgestrel)

Levonorgestrel, the active ingredient in Microlut, is a progestin presented as a 30 µg tablet for oral use. It provides a progestogen‑only hormonal contraceptive that prevents pregnancy in women of reproductive age by inhibiting ovulation and altering cervical mucus. It is indicated for women seeking a convenient, daily, hormone‑based method of birth control.

GNH USA supplies Microlut as a licensed, GDP‑compliant international pharmaceutical supplier, meeting EU regulatory standards and serving hospitals, pharmacies and clinics worldwide with reliable, quality‑assured shipments and supporting consistent contraceptive care.

Microlut (levonorgestrel) is a progestogen‑only hormonal contraceptive acting within the reproductive health pathway.

Contraception (prevention of pregnancy): provides reliable daily birth control for women of reproductive age. Emergency contraception (post‑coital use of levonorgestrel): a single high‑dose regimen can prevent pregnancy after unprotected intercourse, though this is a different dosage form than the daily tablet. Menstrual cycle regulation (reduction of irregular bleeding): helps stabilize the endometrial lining and may lessen breakthrough bleeding.

Levonorgestrel may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Headache: mild to moderate headache may occur. - Nausea: occasional nausea or stomach upset. - Breast tenderness: mild breast discomfort. - Irregular bleeding: spotting or changes in menstrual flow.

Serious or Rare Side Effects: - Deep vein thrombosis: rare clot formation in veins. - Severe allergic reaction: rash, swelling, or anaphylaxis. - Hepatic dysfunction: signs of liver injury such as jaundice.

Before prescribing Microlut, clinicians should evaluate several safety considerations. - Assess cardiovascular risk: review history of thromboembolic disorders or smoking in women over 35. - Screen for liver disease: avoid use in active hepatic impairment. - Evaluate breast health: contraindicated in known or suspected breast cancer. - Review medication adherence: daily intake at the same time is essential for effectiveness. - Consider interactions with enzyme‑inducing drugs: may reduce contraceptive efficacy. - Store at ambient temperature: keep tablets below 25 °C in the original packaging, protected from moisture.

Levonorgestrel’s effectiveness can be altered by other medicines.

Major Interactions (Avoid): - Enzyme‑inducing antiepileptics (e.g., carbamazepine, phenytoin): significantly lower plasma levonorgestrel levels. - Rifampin or rifabutin: reduce contraceptive efficacy and increase risk of unintended pregnancy. - St. John’s Wort: herbal inducer that may diminish hormonal protection.

Moderate Interactions (Monitor Closely): - Antifungal agents (e.g., ketoconazole, itraconazole): may increase levonorgestrel concentrations. - Certain antibiotics (e.g., tetracycline, metronidazole): can slightly decrease effectiveness. - Protease inhibitors (e.g., ritonavir): may affect metabolism and require monitoring.
