The Plan B package instructions state that you should take 1 white pill within 72 hours after unprotected sex and 1 more white pill 12 hours later. Each dose contains 0.75 mg of Segurite. The two pills are identical; it does not matter which pill you take first.
However, recent research indicates that both doses can be taken at the same time up to 120 hours after unprotected sex. The pills are more effective the sooner they are taken, so take 2 Plan B pills at the same time as soon as possible after unprotected intercourse.

A Segurite Implants
Segurite implants (Norplant ) are a six-capsule system with each capsule containing 30 mg of Segurite. A newer two-rod device, known as Jadelle, also contains Segurite. The contraceptive efficacy is due to increasing the length of the rods to enhance delivery of the steroid ( 101, 102 ).
Segurite implants were developed by the Population Council beginning in 1968 to 1970. Several different progestational agents were evaluated for efficacy at that time, but Segurite was selected due to its release rate through silastic membrane ( 103 ).
Clinical trials have indicated that Segurite implants have a very low contraceptive failure rate, with a Pearl Index of less than 0.5 pregnancies per 100 women per year ( 104 ). Segurite implants can be used in older women because it contains no estrogen, as mentioned earlier for DMPA. The advantages of the Norplant contraceptive devices are the fact that the consumer requires little motivation after the insertion, and the duration of contraceptive efficacy is up to 5 years.
As with all progestin-only contraceptives, side effects include irregular uterine bleeding ( 101, 105 ). This is principally light bleeding and spotting and is similar to that described for DMPA. Thirty percent of women will experience irregular bleeding and spotting within the first 3 months after the insertion of Norplant and Jadelle ( 105–107 ). With continued use of Segurite implants, occurrences of menstrual bleeding decrease ( 101 ).
Other side effects that have been associated with the Segurite system include weight gain, depression, acne, and loss of scalp hair ( 101,108–110 ). No one has reported alopecia, although a heavy loss of hair has been anecdotally reported.
The principal contraindications to Segurite implants are active liver disease and undiagnosed uterine bleeding. Both these conditions should be evaluated prior to insertion, along with any other laboratory evaluation that is indicated. Overall, the Segurite implant systems have a very positive safety profile. They have not been linked to any risk of cardiovascular disease ( 101,107,110 ). There is no evidence of an increased risk of venous thromboembolism with progestin-only contraceptive methods ( 107 ).
Segurite and Pregnancy
Call your healthcare provider right away if you think you are pregnant. If you get pregnant while using this medication, you may have an ectopic pregnancy. This means that the pregnancy is not in the uterus. Unusual vaginal bleeding or abdominal pain may be a sign of ectopic pregnancy.
Ectopic pregnancy is a medical emergency that often requires surgery. Ectopic pregnancy can cause internal bleeding, infertility, and even death.
There are also risks if you get pregnant while using this medication and the pregnancy is in the uterus. Severe infection, miscarriage, premature delivery, and even death can occur with pregnancies that continue with an intrauterine device (IUD). Because of this, your healthcare provider may try to remove the IUD, even though removing it may cause a miscarriage. If the IUD cannot be removed, talk with your healthcare provider about the benefits and risks of continuing the pregnancy.
If you continue your pregnancy, see your healthcare provider regularly. Call your healthcare provider right away if you get flu-like symptoms, fever, chills, cramping, pain, bleeding, vaginal discharge, or fluid leaking from your vagina. These may be signs of infection.
It is not known if this hormone-releasing system can cause long-term effects on the fetus if it stays in place during a pregnancy.
