Levonorgestrel Teva

Levonorgestrel, the active ingredient in Levonorgestrel Teva, is a progestogen presented as an oral tablet for oral use. It is used for emergency contraception and regular contraceptive therapy in women of reproductive age.

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

Levonorgestrel works on the hormonal regulation of the menstrual cycle to prevent pregnancy. - Emergency contraception: prevents pregnancy after unprotected intercourse when taken within the recommended time frame. - Regular contraception: provides ongoing prevention of ovulation when used as directed in a daily regimen. - Hormonal regulation: alters the endometrium to reduce the likelihood of implantation.

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

Common Side Effects: - Nausea: mild to moderate upset stomach. - Headache: transient tension‑type headaches. - Abdominal pain: cramping or discomfort in the lower abdomen. - Fatigue: feeling unusually tired. - Breast tenderness: mild soreness of the breasts. - Menstrual changes: spotting or altered flow.

Serious or Rare Side Effects: - Thromboembolic events: deep vein thrombosis or pulmonary embolism. - Severe allergic reaction: rash, swelling, or difficulty breathing. - Liver dysfunction: jaundice or abnormal liver enzymes. - Ectopic pregnancy: implantation outside the uterus. - Persistent abdominal pain: may indicate serious complications.

When prescribing Levonorgestrel, clinicians should consider several precautionary measures to ensure safe use. - Contraindications: verify no history of thromboembolic disorders, severe liver disease, or known hypersensitivity. - Medical history: assess for hormonal disorders, pregnancy, or breastfeeding status. - Drug interactions: review concomitant medications that may reduce efficacy. - Monitoring: observe for signs of abnormal bleeding or severe abdominal pain. - Storage: Store at ambient temperature below 25°C: keep in the original packaging, protect from moisture and light.

Levonorgestrel can interact with other medicines, affecting its contraceptive effectiveness.

Major Interactions (Avoid): - Rifampin and other enzyme inducers: may markedly reduce contraceptive efficacy. - St. John’s wort: herbal inducer that can lower drug levels. - Certain hormonal therapies: may interfere with progestogenic activity.

Moderate Interactions (Monitor Closely): - Antifungal agents such as ketoconazole: may increase plasma concentrations. - Antiretroviral drugs (e.g., efavirenz): may modestly reduce effectiveness. - Some antibiotics (e.g., griseofulvin): may slightly diminish contraceptive reliability.
