Postinor-Uno can cause serious side effects including:
- Pelvic inflammatory disease (PID). Some intrauterine device (IUD) users get a serious pelvic infection called pelvic inflammatory disease. PID is usually sexually transmitted. You have a higher chance of getting PID if you or your partner have sex with other partners. PID can cause serious problems such as infertility, ectopic pregnancy or pelvic pain that does not go away. PID is usually treated with antibiotics. More serious cases of PID may require surgery. A hysterectomy (removal of the uterus) is sometimes needed. In rare cases, infections that start as PID can even cause death.
- Tell your healthcare provider right away if you have any of these signs of PID: long-lasting or heavy bleeding, unusual vaginal discharge, low abdominal (stomach area) pain, painful sex, chills, or fever.
- Life-threatening infection. Life-threatening infection can occur within the first few days after the IUD is placed. Call your healthcare provider if you develop severe pain within a few hours after the IUD is placed.
- Embedment. IUD may become attached to the uterine wall. This is called embedment. If embedment happens, this medication may no longer prevent pregnancy and you may need surgery to have it removed.
- Perforation. The IUD may go through the uterus. This is called perforation. If your uterus is perforated, this medication may no longer prevent pregnancy. It may move outside the uterus and can cause internal scarring, infection, or damage to other organs, and you may need surgery to have the IUD removed.
Common side effects of Postinor-Uno include:
- Emergency contraception pills will not work if you are already pregnant and should not be used during pregnancy.
- Postinor-Uno is thought to enter human milk after oral administration and should be used cautiously in nursing mothers.
- severe lower abdominal pain (3 to 5 weeks after taking Postinor-Uno)
- have had a heart attack
- have had a stroke
- were born with heart disease or have problems with your heart valves

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 Postinor-Uno. 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.
