Levonorgestrel is a synthetic progestogen used in hormonal contraception to prevent pregnancy.

- Emergency contraception: prevents pregnancy after unprotected intercourse by inhibiting or delaying ovulation. - Regular contraception: maintains contraceptive efficacy when taken as directed in progestogen‑only regimens. - Non‑estrogen contraceptive option: provides reliable birth control for women who cannot use estrogen‑containing products.

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

Common Side Effects: - Nausea: mild stomach upset. - Headache: tension‑type headache. - Breast tenderness: mild discomfort. - Irregular bleeding: spotting or changes in menstrual flow.

Serious or Rare Side Effects: - Thromboembolic events: rare blood clot formation. - Severe allergic reaction: rash, swelling, difficulty breathing. - Liver dysfunction: abnormal liver enzymes or jaundice.

When prescribing levonorgestrel, clinicians should consider several precautionary measures to ensure safe use.

- Contraindications: avoid in women with known hypersensitivity to levonorgestrel or other progestogens. - Pregnancy status: not indicated for ongoing pregnancy; confirm negative pregnancy test before use. - Breastfeeding: assess risk‑benefit; limited data, use only if clearly needed. - Drug interactions: review concomitant medications that may reduce efficacy, such as enzyme inducers. - Underlying conditions: caution in patients with active liver disease or thromboembolic disorders. - Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture and light.

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

Major Interactions (Avoid): - Rifampicin, carbamazepine, phenytoin, and St. John’s wort: strong enzyme inducers that markedly reduce levonorgestrel levels, risking contraceptive failure. - Certain antiretrovirals (e.g., efavirenz): may lower plasma concentrations, compromising efficacy.

Moderate Interactions (Monitor Closely): - Antifungal azoles (ketoconazole, itraconazole): may increase levonorgestrel exposure, potentially enhancing side effects. - Anticonvulsants with moderate inducing effect (e.g., phenobarbital): may modestly reduce effectiveness. - Hormonal therapies (e.g., estrogen‑containing contraceptives): may alter bleeding patterns but are generally safe.
