Navela (Levonorgestrel)

Levonorgestrel, the active ingredient in Navela, is a progestin presented as a tablet for oral use. It is used as an emergency contraceptive to prevent pregnancy after unprotected intercourse. Navela provides a rapid, non‑prescription option for post‑coital birth control.

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

Levonorgestrel is a progestin that acts within the hormonal pathway of contraception.

- Emergency contraception: prevents pregnancy when taken shortly after unprotected sex. - Post‑coital contraception: offers a non‑prescription option to reduce the risk of unintended pregnancy. - Prevention of unintended pregnancy after contraceptive failure: provides an additional safeguard when regular methods fail.

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

Common Side Effects: - Nausea: mild to moderate stomach upset. - Abdominal pain: cramping or discomfort. - Fatigue: feeling unusually tired. - Headache: mild to moderate intensity. - Dizziness: brief episodes of light‑headedness. - Menstrual changes: spotting or altered timing.

Serious or Rare Side Effects: - Severe allergic reaction: rash, swelling, or difficulty breathing. - Chest pain: unexpected discomfort in the chest area. - Severe abdominal pain: intense, persistent cramps. - Vomiting blood: sign of gastrointestinal bleeding. - Fainting: sudden loss of consciousness.

Before using Navela, consider the following safety measures.

- Timing of administration: take as soon as possible after unprotected intercourse, preferably within 72 hours. - Contraindications: avoid if there is a known hypersensitivity to levonorgestrel. - Medical conditions: use with caution in women with active liver disease or hormone‑sensitive cancers. - Drug interactions: be aware of enzyme‑inducing medications that may lower effectiveness. - Pregnancy testing: not indicated for established pregnancy. - Store at ambient temperature: keep below 25°C, retain in the original pack, and protect from moisture.

Levonorgestrel can interact with other medicines, affecting its efficacy.

Major Interactions (Avoid): - Enzyme inducers (e.g., rifampicin, carbamazepine): may markedly reduce effectiveness. - Antifungal agents (e.g., griseofulvin): may lower drug levels. - Antiretroviral drugs (e.g., efavirenz): may decrease efficacy.

Moderate Interactions (Monitor Closely): - Anticonvulsants (e.g., phenytoin): may modestly reduce effect. - Herbal supplements (e.g., St. John’s wort): may affect hormone levels. - Certain antibiotics (e.g., ampicillin): limited evidence, monitor for reduced efficacy.
