Anlitin is a brand medication that contains Levonorgestrel, which belongs to a class of medications called progestin contraceptives. It resembles the female hormone progesterone in our bodies. It works by inhibiting the release of an egg from the ovary, preventing sperm fertilisation of the egg by making vaginal fluid thicker, or changing the uterine lining to prevent attachment of a fertilised egg. It is an emergency contraceptive used by women after birth control failure (such as a broken condom) or unprotected sex.
Anlitin is available as tablets. It can be taken with or without food.
For emergency contraception, take one 0.75mg tablet as soon as possible within 72 hours of unprotected sex, followed by a second 0.75 mg tablet 12 hours after the first dose.
Alternatively, you may take one 1.5mg tablet once as soon as possible within 72 hours of sexual intercourse. Take another dose if you vomit within 2-3 hours after taking this medication.
Common side effects of Anlitin include nausea, vomiting, abdominal pain, dizziness, headache, fatigue, menstrual irregularity, breast pain or mood changes.
