Norlevo (Levonorgestrel)

Levonorgestrel, the active ingredient in Norlevo, is a progestin presented as an oral tablet for oral use. It is used for emergency contraception after unprotected intercourse in women of reproductive age.

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

Levonorgestrel is a progestin used in the hormonal pathway of emergency contraception.

- Unprotected intercourse: reduces the risk of pregnancy when taken within 72 hours after exposure. - Contraceptive failure: provides backup protection after a missed dose of regular hormonal contraception. - Emergency contraception for women of reproductive age: offers a non‑prescription option to prevent unintended pregnancy.

Levonorgestrel is generally well tolerated, but adverse reactions can occur.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Abdominal pain or cramps: transient discomfort. - Headache: occasional tension‑type headache. - Dizziness or light‑headedness. - Fatigue or tiredness. - Menstrual changes: spotting, earlier or later onset of the next period.

Serious or Rare Side Effects: - Severe allergic reaction: rash, itching, swelling, or difficulty breathing. - Chest pain or palpitations. - Persistent vomiting or vomiting blood. - Severe abdominal pain that does not resolve. - Signs of liver dysfunction: jaundice or dark urine.

When using Norlevo, consider the following safety measures.

- Timing of intake: take as soon as possible after unprotected intercourse for maximum effectiveness. - Weight considerations: efficacy may be reduced in individuals with higher body weight or BMI. - Medical history: disclose liver disease, hormonal disorders, or previous thromboembolic events to a healthcare professional. - Concurrent medications: review all current medicines for potential interactions. - Pregnancy testing: the product is not intended for use if pregnancy is already established. - Store at ambient temperature: keep in the original packaging, protect from moisture and heat.

Levonorgestrel may interact with other medicines that affect hormone metabolism.

Major Interactions (Avoid): - Rifampicin or other strong enzyme inducers: can markedly lower contraceptive effectiveness. - Anticonvulsants such as carbamazepine, phenytoin, or phenobarbital: may reduce plasma levels. - St. John’s wort: herbal inducer that can diminish efficacy.

Moderate Interactions (Monitor Closely): - Hormonal contraceptives used concurrently: backup non‑hormonal contraception may be advisable. - Antifungal azoles (e.g., ketoconazole): may increase levonorgestrel concentrations. - Certain antiretroviral protease inhibitors: potential alteration of drug levels requiring clinical monitoring.
