Norlevo (Levonorgestrel)

Levonorgestrel, the active ingredient in Norlevo, is a progestogen presented as a 1.5 mg tablet for oral use. It is indicated for emergency contraception to prevent pregnancy after unprotected sexual contact or contraceptive failure, and is available without prescription in many EU countries.

GNH USA supplies Norlevo as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, providing reliable sourcing for emergency contraceptive needs. The company adheres to stringent quality standards and regulatory requirements across all markets.

Levonorgestrel, a progestogen used in emergency contraception, acts on the reproductive hormonal pathway to prevent pregnancy.

- Unprotected intercourse: prevents pregnancy when taken within the recommended time window after condom breakage or missed contraception. - Contraceptive failure: provides a backup method after missed oral contraceptive pills or device malfunction. - Emergency contraception: offers a non‑prescription option to reduce the risk of unintended pregnancy.

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

Common Side Effects: - Nausea: mild to moderate stomach upset. - Headache: transient cranial pain. - Fatigue: feeling of tiredness. - Menstrual changes: spotting or early onset of next period.

Serious or Rare Side Effects: - Allergic reaction: rash, itching, swelling, or difficulty breathing. - Severe abdominal pain: may indicate ectopic pregnancy. - Thromboembolic events: rare clotting disorders.

When using Norlevo, consider the following precautions to ensure safe and effective use.

- Timing of intake: take as soon as possible after unprotected intercourse, preferably within 72 hours. - Repeated use: avoid using emergency contraception as a regular birth control method. - Medical conditions: consult a healthcare professional if you have liver disease, hormonal disorders, or a history of blood clots. - Medication interactions: inform your provider about concurrent use of enzyme‑inducing drugs or hormonal therapies. - Pregnancy status: confirm you are not already pregnant before use. - Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture and direct sunlight.

Levonorgestrel can interact with several medicines that affect its efficacy or safety.

Major Interactions (Avoid): - Rifampicin, carbamazepine, phenytoin: strong enzyme inducers that markedly reduce levonorgestrel effectiveness. - Antifungal azoles (ketoconazole, itraconazole): may increase levonorgestrel levels, raising risk of hormonal side effects. - St. John’s wort: herbal inducer that can lower drug exposure.

Moderate Interactions (Monitor Closely): - Hormonal contraceptives: may require additional dosing if taken together. - Anticonvulsants (phenobarbital): moderate reduction in efficacy. - Antiretroviral protease inhibitors: may alter plasma concentrations, necessitating clinical monitoring.
