Levonorgestrel is categorized as a morning-after pill, serving as an emergency contraceptive. Its primary function is to forestall pregnancy subsequent to instances of unprotected sexual activity or when other methods of birth control fail. This contraceptive mechanism operates by temporarily postponing the release of an egg from the ovary, thereby preemptively averting the initiation of pregnancy. For optimal efficacy, levonorgestrel should be ingested within 72 hours of unprotected sex or birth control mishaps.
Uses and Dosage
Levonorgestrel is presented in tablet form for oral consumption. If you are utilizing levonorgestrel as a single tablet product, take one tablet as promptly as possible within a 72-hour window following unprotected sexual intercourse. Should you be employing levonorgestrel as a two tablet product, the advised course involves taking one tablet without delay within 72 hours after unprotected sexual intercourse, followed by a second dose 12 hours later.
Optimal effectiveness is achieved when levonorgestrel is ingested without delay following unprotected sexual intercourse. Adhere rigorously to the prescribed regimen for levonorgestrel usage.
Should you experience vomiting within 2 hours of taking a levonorgestrel dose, it is advisable to contact your doctor. In such instances, it might be necessary to take an additional dose of the medication.
Given the potential for swift post-treatment pregnancy, it’s prudent to either continue your regular birth control method or commence regular birth control immediately following the use of levonorgestrel.
Some side effects may occur that usually do not need medical attention:
