Plan B is a brand of progestin-only pills approved by the U.S. FDA specifically for emergency contraception. Plan B actually consists of two emergency contraceptive pills; each pill contains the progestin hormone levonorgestrel. Plan B (also known as the morning after pill) can be taken:
- In one dose (at the same time)
- In two doses (12 hours apart)
- Purchase Plan B Emergency Contraception. Plan B is available over the counter for women 17 and older and can usually be found at your local pharmacy. A prescription for Plan B is needed for females under the age of 17, or if a woman is seeking other forms of progestin-only emergency contraception. You must make an appointment to see a healthcare provider in order to obtain these prescriptions. It may also be helpful to obtain this prescription ahead of time or to have Plan B at home, so it can be quickly and easily avaialble should you need it.
- Swallow the pills in the first dose as soon as possible. These pills can be taken up to up to 120 hours (or 5 days) after having unprotected sex. However, the sooner they are taken, the more effective they will be.
- Swallow the second dose 12 hours after taking the first dose (if taking the pills in two doses). Be sure to use an anti-nausea medication one hour before taking the second dose if you threw up after the first dose.
- Do not take any extra pills. Even if the second dose is vomited, as taking more pills probably will not reduce the risk of pregnancy. They can, however, make you sick to the stomach.
- The Plan B pill pack consists of 2 pills. The first white pill is taken and then the second white pill is taken 12 hours later. A woman can also choose to take both white pills together in one dose.
- Prescription progestin-only pill packs consist of 2 packs with 20 pills in each. When using Ovrette, first take all 20 yellow pills as the first dose and then take an additional (second pack) of 20 yellow pills 12 hours later. You can also choose to take all 40 yellow pills together in one dose.
- After taking these pills, be prepared for possible Plan B side effects. Some side effects that are associated with Progestin-only or Plan B emergency contraception:
- Your next period may be earlier or later than usual
- Nausea and vomiting may occur
- Your flow may be lighter, more spotty, heavier, or the same as usual
- You may experience headaches
- Breast tenderness could be common
- Dizziness is also common
- Follow-up procedures after taking Plan B or Ovrette. You may want to make an appointment with your doctor if:
- You do not have your period in three weeks
- If you have pregnancy symptoms
- If you take a home pregnancy test and get a positive result
- Be sure to use an additional method of contraception. Emergency contraception, like the morning after pill, does not continue to prevent pregnancy during the rest of your menstrual cycle, so make sure to use other birth control methods (like condoms, female condom, Today Sponge or spermicide) in order to prevent an unintended pregnancy.
- These directions apply to the old Plan B (2-pill) formulation.
Information on: How to Buy and Use Plan B One-Step
- Although there have been no reports of serious complications among the thousands of females who have used this emergency contraception, mild Plan B side effects could occur but will usually just last a day or two.
- Plan B or Ovrette may cause nausea and vomiting. A female can take an anti-nausea medication, like Dramamine or Bonine, one hour before taking the emergency contraceptive pills to reduce the risk of nausea.
Just remember to read and follow the precautions on the package insert of these anti-nausea medications as the side effects of these types of medicines may include drowsiness.
- Try not to rely on emergency contraception as your main form of birth control. Frequent use of Plan B or progestin-only emergency contraception can cause periods to become irregular and unpredictable.
