Some types of emergency contraception, such as Plan B, do not affect an established pregnancy, but they can help keep pregnancy from occurring. Anyone looking to buy Plan B discreetly can do so online.

Plan B is one type of emergency contraception that is available in pill form. In this article, “sex” refers to sex that could lead to pregnancy.

Below, we look at where to get Plan B, possible side effects, and some frequently asked questions.

A quick look at the best ways to get Plan B

Plan B is a type of emergency contraception. Another name is the “morning-after pill.”

It contains the hormone levonorgestrel, and it works by preventing the ovaries from releasing eggs. It can also stop eggs from becoming fertilized.

Anyone interested in Plan B should take it as soon as possible after sex without contraception.

As Planned Parenthood notes, if a person takes Plan B within 72 hours after sex without contraception, it is 75–89% effective in preventing pregnancy.

However, this may not be the most effective type of emergency contraceptive. The Centers for Disease Control and Prevention (CDC) report that medications containing levonorgestrel, such as Plan B, are less effective than those containing ulipristal acetate, such as Ella.

A person can purchase Plan B many places in the United States, both online and in person.

Best for immediate pick-up: Drugstores and pharmacies

Any person of any age or gender can purchase Plan B in this way.

Some insurance plans cover Plan B, although people may need to pay out of pocket and make a claim with their insurance provider for reimbursement. Some insurers may require a doctor’s prescription before they cover the cost. It is important for each person to check their insurance coverage.

Plan B is most effective when a person takes it within 24 hours after sex without contraception. The longer the time gap, the less effective it becomes. With this in mind, online options may be risky, unless a person picks up their Plan B the same day.

Prices and insurance coverage are other factors to consider.

Some common side effects of Plan B include:

Research suggests that the common side effects of levonorgestrel pills, such as Plan B, are usually not serious. It also reports that adverse reactions are rare.

A 2019 analysis suggests that levonorgestrel contraceptive pills may be less effective for those with a higher body mass index.

Anyone taking any of these medications should avoid Plan B and other products that contain levonorgestrel:

  • the antibiotic l medication rifampin
  • the antifungal medication griseofulvin
  • some HIV medications
  • some antiseizure medications
  • St John’s Wort

Other types of emergency contraceptive pills that contain levonorgestrel include:

  • Take Action
  • My Way
  • Option 2
  • Preventeza
  • AfterPill
  • My Choice


Ella contains a different active ingredient: ulipristal acetate. The CDC reports that this may be more effective in preventing pregnancy than levonorgestrel, which is in Plan B.


A copper intrauterine device (IUD) is another option. It also contains plastic, and a doctor inserts it into the uterus up to 5 days after unprotected sex. The copper that the IUD releases stops an egg from fertilizing.

A person should consider seeking medical attention if:

  • They develop painful stomach cramps after taking Plan B.
  • They are unsure whether they can take Plan B with their other medication.
  • They think they may already be pregnant.
