Levonorgestrel Norfri

Levonorgestrel, the active ingredient in Levonorgestrel Norfri, is a progestin presented as an oral dosage form for oral use. It is employed to prevent pregnancy, including as an emergency contraceptive, by inhibiting ovulation and altering cervical mucus. GNH USA supplies Levonorgestrel Norfri as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Levonorgestrel Norfri is a progestin that acts within the hormonal contraceptive pathway to prevent fertilisation. - Emergency contraception: reduces the risk of pregnancy when taken shortly after unprotected intercourse. - Pregnancy prevention: incorporated into hormonal regimens to inhibit ovulation and block fertilisation. - Hormonal contraceptive regimen: used as a progestin‑only component in combined or standalone birth‑control pills to maintain contraceptive efficacy.

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

Common Side Effects: - Nausea: mild to moderate stomach upset after ingestion. - Headache: transient tension‑type headaches. - Breast tenderness: temporary discomfort or swelling of breast tissue. - Irregular bleeding: spotting or changes in menstrual flow. - Fatigue: feeling unusually tired. - Mood changes: brief fluctuations in mood or emotional state.

Serious or Rare Side Effects: - Thromboembolic events: rare blood clot formation in veins or arteries. - Severe allergic reaction: anaphylaxis presenting with rash, swelling, or breathing difficulty. - Liver dysfunction: abnormal liver enzymes or jaundice. - Ectopic pregnancy: implantation outside the uterus if fertilisation occurs despite contraception. - Persistent high blood pressure: sustained elevation requiring medical attention.

Before using Levonorgestrel Norfri, consider the following safety measures. - Medical history review: assess for prior thromboembolic disease, liver disorders, or hormone‑sensitive cancers. - Concurrent medications: evaluate for drugs that may reduce contraceptive effectiveness, such as enzyme inducers. - Timing of administration: take as soon as possible after unprotected intercourse for optimal emergency effect. - Pregnancy testing: avoid use if a confirmed pregnancy already exists. - Breastfeeding: discuss potential risks with a healthcare professional before use. - Store at ambient temperature below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Levonorgestrel can interact with several medicines, altering its efficacy or safety profile.

Major Interactions (Avoid): - Enzyme inducers (e.g., rifampicin, carbamazepine, phenytoin): may markedly reduce contraceptive effectiveness. - Antifungal azoles (e.g., ketoconazole): can increase levonorgestrel plasma levels, raising side‑effect risk. - Protease inhibitor antiretrovirals: may alter hormone metabolism and affect efficacy.

Moderate Interactions (Monitor Closely): - Certain antibiotics (e.g., ampicillin): may slightly diminish contraceptive reliability. - Anticonvulsants (e.g., valproate): may have a moderate impact on hormone levels. - Herbal supplements (e.g., St. John’s wort): can reduce levonorgestrel effectiveness.
