Luvigen pills contain levonorgestrel, which is a synthetic progestogen used mainly as an emergency contraceptive to prevent pregnancy after unprotected sexual intercourse or contraceptive failure[13][15]. The medication is most effective when taken as soon as possible within 72 hours after the event.
- Luvigen is not intended for routine contraception, but for emergency situations such as missed contraceptive doses, condom breakage, or unplanned intercourse[15].
- It works by preventing or delaying ovulation, and it may also prevent fertilization or implantation depending on when it is taken in relation to the menstrual cycle[15].
- The most common regimen involves taking one tablet of levonorgestrel (usually 0.75 mg) as soon as possible, followed by a second tablet 12 hours later; newer regimens may offer a single-dose option (usually 1.5 mg)[15].
- Common side effects include nausea, abdominal pain, fatigue, headache, dizziness, and menstrual changes; vomiting within two hours of taking a dose may require repeating the dose[15].
- Luvigen is generally available over the counter for women 17 years and older, but prescription may be required for younger individuals[15].
