Navela (Levonorgestrel)

Levonorgestrel, the active ingredient in Navela, is a progestogen presented as a tablet for oral use. It is employed to prevent or delay pregnancy when taken after unprotected sexual intercourse. GNH USA supplies Navela as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Navela, a levonorgestrel‑based emergency contraceptive, works within the reproductive hormone pathway to prevent unintended pregnancy. - Emergency contraception: provides post‑coital protection when taken within the approved time window. - Prevention of unintended pregnancy: reduces the risk of conception after contraceptive failure. - Ovulation delay: inhibits or postpones the release of an egg, decreasing the chance of fertilisation.

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

Common Side Effects: - Nausea: mild to moderate upset stomach. - Abdominal pain: cramping or discomfort in the lower abdomen. - Headache: transient tension‑type headache. - Dizziness: brief episodes of light‑headedness. - Fatigue: feeling unusually tired. - 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: may indicate ectopic pregnancy. - Chest pain: could signal cardiovascular involvement. - Persistent vomiting: may lead to dehydration. - Liver dysfunction: jaundice or abnormal liver tests. - Thromboembolic events: rare clotting disorders.

When using Navela, certain precautions should be observed to ensure safety and effectiveness. - Timing of intake: take as soon as possible after unprotected intercourse, ideally within 72 hours. - Contraindications: avoid if known hypersensitivity to levonorgestrel or any tablet components. - Pregnancy status: not indicated for use if already pregnant; a pregnancy test may be considered. - Drug interactions: be aware of enzyme‑inducing medications that may lower efficacy. - Medical conditions: use with caution in patients with hepatic impairment or uncontrolled hypertension. - Store at ambient temperature: keep in the original packaging, protect from moisture and excessive heat.

Levonorgestrel can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid): - Rifampicin: strong enzyme inducer that markedly reduces levonorgestrel effectiveness. - Anticonvulsants (phenytoin, carbamazepine, phenobarbital): lower plasma levels, compromising emergency protection. - St. John's wort: herbal inducer that may diminish contraceptive effect.

Moderate Interactions (Monitor Closely): - Azole antifungals (ketoconazole, itraconazole): may increase levonorgestrel concentrations, raising side‑effect risk. - Antiretroviral efavirenz: can reduce levonorgestrel exposure. - Combined hormonal contraceptives: concurrent use may require additional non‑hormonal backup methods.
