Indications & Clinical Uses

  • Levonorgestrel is used as an emergency contraceptive to reduce the risk of pregnancy when taken within 72 hours after unprotected intercourse or contraceptive failure. It is designed for occasional use and should not replace routine birth control methods. The medication works by temporarily delaying ovulation to prevent fertilization.

Side Effects

  • After taking levonorgestrel, some users may experience mild nausea, fatigue, or breast tenderness. These effects are generally temporary and resolve within a few days. Headaches or menstrual changes, such as spotting, may also occur but are not uncommon.

Precautions & Warnings

  • Levonorgestrel should be used as soon as possible after unprotected sex for maximum effectiveness. It is not effective if pregnancy has already occurred. Users with a history of severe allergic reactions to levonorgestrel or any component of the tablet should avoid it. Consult a healthcare provider if vomiting occurs within two hours of taking the dose.

Avoid Interactions

  • Certain medications, such as those for epilepsy, HIV, or tuberculosis, may reduce the effectiveness of levonorgestrel. Herbal supplements like St. John's wort can also interfere with its action. Alcohol and food do not significantly impact its performance, but always disclose all medications to a healthcare provider before use.
