Drug Details

Levonorgestrel, commonly known as Plan B One-Step, is an emergency contraceptive designed to prevent pregnancy after unprotected sex or a failure in other birth control methods, such as a broken condom. It is most effective when taken within 72 hours of the incident but should not be used as a regular form of contraception. Levonorgestrel works by temporarily halting ovulation, making it difficult for sperm to reach the uterus, and preventing a fertilized egg from implanting in the uterus. It is important to note that this medication will not terminate an existing pregnancy or offer protection against sexually transmitted infections (STIs) such as HIV, gonorrhea, or chlamydia. Certain factors may affect the efficacy of Levonorgestrel. For instance, it may be less effective in women who weigh over 164 pounds (74 kilograms) or those who have taken specific other medications in the past month. Therefore, consulting a healthcare professional is advised to ascertain if this medication is suitable for you. Always check the product label for ingredients, as manufacturers may alter them, and similarly named products can have different compositions intended for various uses. Misusing any product can be harmful.
