Levunique

Levonorgestrel, the active ingredient in Levunique, is a synthetic progestin presented as an oral tablet for systemic use. It prevents pregnancy by inhibiting or delaying ovulation and may also alter tubal motility and the endometrial lining, reducing the likelihood of fertilization and implantation. Levunique is indicated for emergency contraception and regular hormonal birth control in women of reproductive age.

GNH USA supplies Levunique as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides regulatory documentation for each batch.

Levonorgestrel is used in hormonal contraceptive pathways to prevent pregnancy. - Emergency contraception: prevents pregnancy after unprotected intercourse when taken within a specified time frame. - Regular contraception: provides ongoing hormonal birth control to inhibit ovulation. - Ovulation suppression: delays or blocks the release of an egg during the menstrual cycle.

Levonorgestrel may cause a range of adverse reactions, varying from mild to serious. Common Side Effects: - Nausea: mild stomach upset that may occur shortly after taking the tablet. - Headache: transient tension‑type headache. - Breast tenderness: temporary discomfort or swelling of the breasts. Serious or Rare Side Effects: - Allergic reaction: rash, itching, swelling, or difficulty breathing indicating hypersensitivity. - Thromboembolic events: rare formation of blood clots that may present as leg pain or swelling. - Liver dysfunction: signs such as jaundice, dark urine, or elevated liver enzymes.

When using Levunique, several precautions should be observed to ensure safety and effectiveness. - Contraindication: Do not use in individuals with known hypersensitivity to levonorgestrel or any tablet components. - Pregnancy: Not intended for use during an established pregnancy; seek medical advice if pregnancy is suspected. - Hepatic disease: Use with caution in patients with severe liver impairment. - Thromboembolic risk: Avoid in women with a history of blood clotting disorders. - Drug interactions: Review concomitant medications that may reduce efficacy, such as enzyme inducers. - Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Levonorgestrel can interact with other medicines, affecting its contraceptive reliability. Major Interactions (Avoid): - Enzyme inducers (e.g., rifampin, carbamazepine, phenytoin): significantly lower levonorgestrel plasma levels. - St. John’s wort: herbal inducer that reduces effectiveness. - Anticonvulsants: certain seizure medications may diminish contraceptive effect. Moderate Interactions (Monitor Closely): - Combined hormonal contraceptives: may increase progestogenic load, requiring clinical assessment. - Antifungal agents (e.g., ketoconazole): can increase levonorgestrel concentrations. - Antiretrovirals (e.g., efavirenz): may modestly reduce efficacy.
