Levonorgestrel Medications

What is Levonorgestrel?

Levonorgestrel is a progestin, a synthetic form of the natural hormone progesterone. It is widely relied upon for family planning and pregnancy prevention. Because different manufacturers produce various formulations, you may encounter several brand names that share the same active ingredient but differ in their concentration or specific combination within a multi-phasic or monophasic pack.

What Levonorgestrel is used for

This hormone is indicated for Contraception, where it works as part of a daily oral regimen to suppress ovulation and alter cervical mucus. It is also used for Emergency Contraception, often referred to as the morning-after pill, to prevent pregnancy after unprotected intercourse or contraceptive failure.

How does Levonorgestrel work?

Levonorgestrel prevents pregnancy primarily by stopping or delaying the release of an egg from the ovaries. It also thickens the mucus at the cervix, which makes it harder for sperm to travel through the female reproductive tract to reach an egg. Effectively, it creates a physiological state that is unfavourable for fertilisation and implantation.

You will find this medication in tablet form, ranging from daily oral contraceptive pills to higher-dose tablets designed for emergency use.
