Generic emergency contraceptives are just as effective as brand-name Plan B
Most generic options contain 1.5mg levonorgestrel

Affordable alternatives available at most pharmacies
Emergency contraception represents a critical healthcare option for individuals seeking pregnancy prevention after unprotected intercourse or contraceptive failure. Generic versions of Plan B have revolutionized accessibility, offering safe and effective alternatives to the brand-name product. By understanding the nuances of these medications, individuals can make informed decisions about their reproductive health.
Generic emergency contraceptives work by preventing or delaying ovulation through a synthetic hormone called levonorgestrel. When understanding the effects of levonorgestrel, it's important to recognize that the medication primarily stops egg release when sperm might be present.
The effectiveness is time-sensitive, with success rates dramatically decreasing over time. Within 24 hours of unprotected intercourse, the medication can prevent pregnancy with approximately 95 percent effectiveness. This rate drops to around 85 percent between 25 and 48 hours, and further reduces to about 58 percent when used between 49 and 72 hours after potential conception.
Several pharmaceutical manufacturers now produce generic emergency contraception, offering more affordable alternatives to brand-name Plan B. These generic versions must meet identical FDA standards for safety and efficacy. When comparing generic vs brand name drugs, patients can typically save significant money without compromising quality.
