Norlevo (Levonorgestrel)

Levonorgestrel, the active ingredient in Norlevo, is a progestogen presented as an oral tablet for emergency contraception. It works by delaying or inhibiting ovulation and may affect fertilization and endometrial receptivity, providing a non‑prescription option to reduce the risk of pregnancy after unprotected sexual activity when taken within a short time frame and is approved for use in many EU countries.

GNH USA supplies Norlevo as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide with a focus on quality assurance and regulatory compliance across regions.

Norlevo (levonorgestrel) is used as an oral hormonal emergency contraceptive to prevent pregnancy after unprotected intercourse.

- Unprotected sexual intercourse: Reduces the risk of pregnancy when taken within 72 hours. - Contraceptive failure (e.g., missed pill): Provides a backup method to prevent unintended pregnancy. - Sexual assault: Offers an immediate option to lower the chance of pregnancy after forced intercourse.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Abdominal pain: cramping or discomfort in the lower abdomen. - Headache: transient tension or migraine‑type pain. - Fatigue: feeling unusually tired or weak. - Dizziness: light‑headed sensation. - 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 may indicate ectopic pregnancy. - Chest pain: unexplained discomfort requiring immediate evaluation. - Persistent vomiting: inability to retain oral medication. - Signs of thromboembolism: sudden leg swelling or shortness of breath.

Before using Norlevo, consider the following precautions: - Timing of intake: should be taken as soon as possible after unprotected intercourse, ideally within 72 hours. - Repeated use: not intended for regular contraception; limit use to emergency situations. - Underlying conditions: consult a healthcare professional if you have a history of hormonal disorders or liver disease. - Drug interactions: review concomitant medications that may affect efficacy. - Pregnancy testing: if menstrual period is delayed beyond three weeks, consider a pregnancy test. - Store at ambient temperature: keep below 25°C, in the original packaging, protected from moisture and direct sunlight.

Levonorgestrel may interact with other medicines that influence its absorption or metabolism.

Major Interactions (Avoid): - Rifampicin, carbamazepine, phenytoin: strong enzyme inducers that can markedly reduce contraceptive effectiveness. - St. John’s wort: herbal inducer that may lower drug levels.

Moderate Interactions (Monitor Closely): - Antifungal azoles (e.g., ketoconazole): may increase levonorgestrel concentrations. - Certain antibiotics (e.g., ampicillin): potential modest reduction in efficacy. - Hormonal contraceptives: concurrent use may require additional dosing guidance. - Anticonvulsants (e.g., valproate): may alter hormonal balance. - Antiretrovirals (e.g., efavirenz): possible decreased effectiveness.
