Norlevo (Levonorgestrel)

Levonorgestrel, the active ingredient in Norlevo, is a progestin presented as a tablet for oral use. It is indicated for emergency contraception to prevent pregnancy after unprotected intercourse or contraceptive failure in women of reproductive age.

GNH USA supplies Norlevo as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, providing reliable sourcing for regulated markets and adhering to strict quality standards with global logistics support.

Levonorgestrel, a progestin used in emergency contraception, works by interfering with ovulation and fertilization.

- Unprotected intercourse: prevents pregnancy when taken within 72 hours after exposure. - Contraceptive failure: provides a backup method after missed or ineffective regular contraception. - Emergency contraception: offers a non‑prescription option for women seeking rapid pregnancy prevention.

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

Common Side Effects: - Nausea: mild stomach upset. - Headache: transient cranial discomfort. - Fatigue: temporary tiredness. - Menstrual changes: spotting or early bleeding.

Serious or Rare Side Effects: - Allergic reaction: rash, swelling, or difficulty breathing. - Severe abdominal pain: possible ectopic pregnancy or other complications.

Use Norlevo only as directed by a qualified healthcare professional.

- Hypersensitivity: avoid if known allergy to levonorgestrel or tablet excipients. - Timing: consider menstrual cycle phase; effectiveness declines with delayed intake. - Not a regular method: do not substitute for ongoing contraceptive regimens. - Pregnancy suspicion: seek medical advice if pregnancy is already established. - Vomiting: if vomiting occurs within 2 hours, consult a clinician for possible re‑dosing. - Store at ambient temperature: keep in the original pack, protect from moisture and heat.

Levonorgestrel may interact with other medicines that affect its metabolism or contraceptive efficacy.

Major Interactions (Avoid): - Rifampicin: induces hepatic enzymes, reducing levonorgestrel effectiveness. - Anticonvulsants (e.g., carbamazepine, phenytoin): lower drug levels, compromising efficacy. - St. John’s wort: herbal enzyme inducer that can diminish contraceptive effect.

Moderate Interactions (Monitor Closely): - Hormonal contraceptives: concurrent use may reduce overall contraceptive protection. - Antifungal azoles (e.g., ketoconazole): may increase levonorgestrel concentrations. - Antiretroviral protease inhibitors: can alter drug metabolism, requiring clinical monitoring.
