We believe in empowering you to make informed decisions about your reproductive health.
EContra One-Step® is part of the commitment, offering you a supportive option when you need it most.

This emergency contraceptive pill has a hormone called Levonorgestrel, which has been used in birth control for many years. EContra One-Step® has a higher amount of Levonorgestrel than regular birth control pills, but it works in a similar way to stop pregnancy. It’s important to know that EContra One-Step® is for emergencies only and should not replace your regular birth control.

EContra One-Step® works by stopping the release of an egg from the ovary. EContra One-Step® is a backup method in situations where regular birth control fails or isn’t used, and it acts in the same way as a birth control pill to prevent pregnancy. It’s important to take EContra One-Step® within 72 hours (3 days) of unprotected sex because the sooner you take it, the better it works.

Timing is very important with EContra One-Step®. The sooner you take it after unprotected sex or if your birth control didn’t work (within 72 hours, or 3 days), the better it works to prevent pregnancy. Studies show that if you take EContra One-Step® correctly, it can greatly lower your chances of getting pregnant. In fact, about 7 out of 8 women who would have gotten pregnant won’t if they use EContra One-Step® as directed.

Taking EContra One-Step® can cause some side effects. These are usually mild and can include changes in your period, stomach pain, nausea, vomiting, tiredness, headaches, dizziness, and sore breasts. Most side effects go away on their own, but call your doctor if you have really bad stomach pain.

Before using EContra One-Step®, talk to your doctor or pharmacist if you take certain medications, like efavirenz (for HIV), rifampin (for tuberculosis), or medications for seizures (epilepsy). These medicines can make EContra One-Step® less effective, so your doctor might suggest a different type of emergency contraception. Remember, EContra One-Step® does not protect against HIV/AIDS or other sexually transmitted infections (STDs).
