Nopregy (Levonorgestrel)

Levonorgestrel, the active ingredient in Nopregy, is a progestogen presented as an oral tablet for oral use. It is employed to prevent pregnancy both as an emergency contraceptive after unprotected intercourse and as a regular hormonal contraceptive for ongoing birth control in women of reproductive age.

GNH USA supplies Nopregy as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides reliable logistics for global distribution to meet regulatory requirements.

Levonorgestrel acts on the hormonal pathways that regulate ovulation and implantation, providing contraceptive effects. - Emergency contraception: prevents pregnancy when taken shortly after unprotected sex. - Regular contraception: maintains ongoing prevention of pregnancy when used as directed. - Ovulation inhibition: suppresses the release of an egg from the ovary during the menstrual cycle.

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

Common Side Effects: - Nausea - Headache - Breast tenderness - Menstrual changes

Serious or Rare Side Effects: - Allergic reaction (anaphylaxis) - Severe abdominal pain - Blood clot formation

When using levonorgestrel, several safety considerations should be observed. - Contraindicated in pregnancy: product must not be taken by women who are pregnant. - Avoid in known hypersensitivity: do not use if allergic to levonorgestrel or excipients. - Do not use with active liver disease: hepatic impairment may increase risk of adverse effects. - Caution in smokers over 35: increased risk of cardiovascular events. - Do not exceed recommended frequency: follow prescriber guidance on timing and repeat dosing. - Store at ambient temperature: keep in original packaging, protect from moisture and heat.

Levonorgestrel can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid): - Rifampin: induces metabolism, reducing contraceptive effectiveness. - Antiepileptic drugs (carbamazepine, phenytoin, phenobarbital): increase hepatic clearance. - St. John’s wort: herbal inducer that may lower drug levels.

Moderate Interactions (Monitor Closely): - Ketoconazole and other azole antifungals: may increase levonorgestrel concentrations. - Efavirenz (antiretroviral): can reduce hormonal efficacy. - Certain antibiotics (rifabutin): may modestly affect hormone levels.
