The plan b pill also called the morning-after pill, is usually the first thing women turn to after unprotected sex. When the pill is taken right within a stipulated period of time, it can prevent any unwanted pregnancy or complications.

What is the plan b pill or morning-after pill?

Plan b pill is an emergency contraception pill that can use after having unprotected sex. It is also called the morning-after pill. However, it is best to take the pill immediately after engaging in unprotected sex to increase its effectiveness.

Plan B Pill

Is it effective?

This pill, when taken within 72 hours after engaging in unprotected sex, is about 89% effective. If taken within 12 hours after sex, it can lower the chance of unwanted pregnancy by about 95%.

How does it work?

Plan b pill is a single tablet emergency contraception that has levonorgestrel which is a female hormone responsible for the prevention of ovulation. This hormone can prevent the ovary from releasing an egg. It can also make it harder for the sperm or the fertilized egg to get to the uterus by causing changes in the lining of the uterus and the cervical mucus. Levonorgestrel is the same hormone used in birth control pills but plan b has a higher dose of it, about 1.5 mg.

Taking the plan b pill

Who should take the plan b pill

Women who have missed the birth control pills, or faced a failure using birth control methods like tearing of the condom, or haven’t used birth control.

When to take the plan b pill

Should be taken within 72 hours of unprotected sex. The sooner it is taken, the pill will be more effective in preventing pregnancy.

How to take the plan b pill

It is a single-dose oral pill that needs to be consumed within 3 days (72 hours) after having unprotected sex. Therefore, it is best to have it ready to prevent any delay.

When to avoid taking the plan b pill

It is best avoided when pregnant, as it will not be effective. Also, do not use the pill if having any allergy to levonorgestrel or other components in the pill. Women weighing over 75 kg or 165 lb may find that plan b isn’t very effective. This is because women with overweight produce more drug-metabolizing enzymes through the liver reducing the effectiveness of the pill.

How often can plan b taken

It should only be taken when the regular birth control pills and methods fail. As it is an emergency pill and so is effective only when taken immediately after unprotected sex or in the event that birth control methods have failed. Also, it does not offer any protection as a long-term contraceptive.

Is it safe to take plan b with the regular birth control method

It only works if taken after unprotected sex and is not effective if taken before engaging in unprotected sex. It is safe to take a plan b pill even if using regular birth control pills, in the event that one missed a few doses. Therefore, it should never be used in place of regular birth control pills.

Side effects

Plan b pill is generally safe when taken as per directions but some possible side effects are –

The pill may cause some unexpected bleeding or spotting in some women during the interval before the next period. If the period is delayed by over a week, check with a doctor and get a pregnancy test. Also, in case of vomiting within two hours of taking the pill, consult the doctor and ask if another pill needs to be taken.

While the pill is largely safe for most women, keep few things in mind to prevent any complications. Drugs that affect the plan b pill –

  • Rifampin
  • Barbiturates

Word of caution

It is important to note that after taking plan b, pregnancy can still occur. Also, if taking plan b pill after unprotected sex and then have unprotected sex again, need to take another pill. A long-term form of birth control is the best way to prevent pregnancy. Long-term birth control options include birth control pills, iucds, implants, shots, patches, latex condoms, and vaginal rings.
