Nebremel (Levonorgestrel)

Levonorgestrel, the active ingredient in Nebremel, is a Progestin presented as a tablet for oral use. It is employed to prevent pregnancy after unprotected intercourse and as a component of hormonal contraceptive regimens.

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

Levonorgestrel acts on the hormonal pathways that regulate ovulation and implantation. - Emergency contraception: prevents pregnancy when taken shortly after unprotected sex. - Prevention of pregnancy: used as a regular hormonal contraceptive to inhibit ovulation. - Ovulation inhibition: delays or suppresses the release of an egg, reducing the chance of fertilisation.

Levonorgestrel may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Abdominal pain: cramping or discomfort in the lower abdomen. - Headache: occasional tension‑type headache. - Dizziness: brief episodes of light‑headedness. - Fatigue: feeling unusually tired. - Menstrual changes: spotting or altered timing of the next period.

Serious or Rare Side Effects: - Allergic reaction: rash, itching, swelling, or difficulty breathing. - Severe abdominal pain: persistent or worsening pain requiring medical attention. - Chest pain: may indicate cardiovascular involvement. - Blood clots: rare thromboembolic events. - Severe vomiting: persistent vomiting leading to dehydration.

Levonorgestrel should be used with awareness of specific safety considerations. - Contraindication: known hypersensitivity to levonorgestrel or any tablet component. - Pregnancy: not indicated for ongoing pregnancy; confirm negative pregnancy test before use. - Breastfeeding: caution advised; consult a healthcare professional. - Drug interactions: avoid concomitant use of strong enzyme inducers that may reduce efficacy. - Medical conditions: use with care in patients with liver disease or uncontrolled hypertension. - Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Levonorgestrel can interact with other medicines that affect hormone metabolism or absorption.

Major Interactions (Avoid): - Rifampicin: may markedly reduce contraceptive effectiveness. - St. John’s wort: herbal inducer that can lower drug levels. - Carbamazepine: enzyme inducer decreasing efficacy. - Phenytoin: reduces plasma concentrations. - Barbiturates: may compromise contraceptive reliability.

Moderate Interactions (Monitor Closely): - Ketoconazole: antifungal that can increase levonorgestrel levels. - Efavirenz: antiretroviral that may modestly lower effectiveness. - Other hormonal therapies: may require dosage adjustment. - Certain antibiotics (e.g., tetracycline): potential for reduced absorption.
