Levonorgestrel

Levonorgestrel is a synthetic progestin hormone commonly used for emergency contraception. It helps prevent pregnancy when taken within a few hours after unprotected intercourse. Levonorgestrel is also found in some birth control pills and intrauterine devices (IUDs) to provide long-term contraception. It works by preventing ovulation, thickening cervical mucus, and altering the uterine lining to prevent implantation. It is a safe and effective method when used as directed.

Uses of Levonorgestrel

• Emergency contraception (morning-after pill)
• Prevention of unintended pregnancy
• Used in hormonal intrauterine devices (IUDs)
• Helps regulate menstrual cycles
• Used in combination birth control pills
• Manages heavy menstrual bleeding

How Levonorgestrel Works

Levonorgestrel prevents pregnancy by delaying or stopping ovulation. It also thickens cervical mucus, making it harder for sperm to reach the egg. Additionally, it alters the uterine lining, reducing the chances of implantation. If pregnancy has already occurred, this medication will not be effective.
