Norlevo (levonorgestrel) is used in the reproductive health pathway as an emergency contraceptive.

- Unprotected intercourse: reduces the chance of pregnancy when taken within 72 hours after sex. - Contraceptive failure: provides backup protection after a missed or ineffective regular contraceptive dose. - Delayed ovulation: inhibits or postpones ovulation to prevent fertilisation.

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

Common Side Effects: - Nausea: mild stomach upset after taking the tablet. - Headache: transient mild to moderate headache. - Fatigue: feeling of tiredness or weakness. - Menstrual changes: spotting, earlier or delayed period.

Serious or Rare Side Effects: - Severe allergic reaction: rash, swelling, difficulty breathing. - Chest pain or palpitations: may indicate cardiovascular issues. - Persistent abdominal pain or vomiting blood: could signal gastrointestinal complications.

When using Norlevo, consider the following precautions.

- Timing of intake: take as soon as possible after unprotected intercourse, ideally within 72 hours. - Weight considerations: effectiveness may be reduced in individuals with BMI >30 kg/m². - Pregnancy testing: avoid use if already pregnant. - Medication interactions: avoid concomitant use with enzyme‑inducing drugs that may lower efficacy. - Medical conditions: consult a healthcare professional if you have liver disease, uncontrolled hypertension, or a history of thromboembolic disorders. - Store at ambient temperature: keep below 25 °C in the original packaging, protect from moisture and direct sunlight.

Levonorgestrel can interact with several medicines; monitor accordingly.

Major Interactions (Avoid): - Enzyme inducers (e.g., rifampicin, carbamazepine, phenytoin): may significantly reduce levonorgestrel effectiveness. - Antifungal agents (e.g., griseofulvin): may lower plasma levels.

Moderate Interactions (Monitor Closely): - Anticonvulsants (e.g., valproic acid): may modestly reduce efficacy. - Certain antibiotics (e.g., ampicillin, tetracycline): limited evidence of interaction, monitor clinical response. - Herbal supplements (e.g., St. John’s wort): may decrease effectiveness.
