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

- Unprotected sexual intercourse: Prevents pregnancy when taken within the recommended time frame after intercourse without barrier or hormonal contraception. - Contraceptive failure: Reduces risk of pregnancy after missed oral contraceptive pills or condom breakage. - Post‑coital emergency use: Provides a non‑prescription option for women seeking rapid prevention of unintended pregnancy within 72 hours.

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

Common Side Effects: - Nausea: transient feeling of sickness, often resolves without treatment. - Abdominal pain: mild cramps or discomfort in the lower abdomen. - Fatigue: temporary feeling of tiredness or low energy. - Headache: mild to moderate headache that usually subsides.

Serious or Rare Side Effects: - Allergic reaction: rash, itching, swelling, or difficulty breathing. - Severe abdominal pain: could indicate ectopic pregnancy. - Vomiting blood or severe gastrointestinal bleeding. - Chest pain or palpitations. - Persistent high fever or severe headache.

Before using Norlevo, consider the following precautions.

- Timing of administration: take as soon as possible after the contraceptive event for maximum effectiveness. - Pregnancy status: do not use if you are already pregnant; emergency contraception is not intended to terminate an existing pregnancy. - Breastfeeding: limited safety data; weigh benefits against potential risks. - Drug interactions: avoid concomitant use with strong enzyme inducers that may reduce efficacy. - Medical conditions: caution in women with known liver disease or hormone‑sensitive cancers. - Store at ambient temperature below 25°C: keep in the original pack, protect from moisture and direct sunlight.

Levonorgestrel can interact with other medicines, requiring attention to avoid reduced effectiveness.

Major Interactions (Avoid): - Rifampicin: strong enzyme inducer that may lower levonorgestrel levels. - Antiepileptic drugs (e.g., carbamazepine, phenytoin): may decrease contraceptive efficacy. - St. John’s wort: herbal inducer that can reduce drug effectiveness.

Moderate Interactions (Monitor Closely): - Antifungal azoles (e.g., ketoconazole): may increase levonorgestrel concentrations. - Antiretroviral protease inhibitors: can alter metabolism and affect efficacy. - Hormonal contraceptives: concurrent use may increase overall hormonal exposure.
