The Morning After Pill (Emergency Contraception, Plan B)

In the UK, the morning after pill is available in two clinically approved forms: ellaOne (ulipristal acetate) and levonorgestrel emergency contraception. Both options are designed to reduce the risk of pregnancy when taken within a specific time window after unprotected sex.

What Is the Morning After Pill Used For?

The morning after pill is used when regular contraception has not worked or was not used. Common reasons include:

• Unprotected sex
• A missed contraceptive pill
• Condom breakage or slippage
• Incorrect use of contraception
• Vomiting after taking the regular contraceptive pill

Emergency contraception works primarily by delaying or preventing ovulation, meaning no egg is released for fertilisation. It does not cause an abortion and will not work if pregnancy has already occurred.

Different Names People Use for the Morning After Pill

For SEO and patient clarity, it’s important to recognise that people search for emergency contraception using many different terms, including:

• Morning after pill
• Plan B pill
• Emergency contraception pill
• After sex pill
• 72 hour pill
• 5 day pill
• Emergency birth control
• Pregnancy prevention pill after sex

All of these terms generally refer to oral emergency contraception, such as ellaOne or levonorgestrel.

ellaOne vs Levonorgestrel (Plan B–Style Pills)

While some people refer to all emergency contraception as “Plan B,” it’s important to understand the differences between available options:

• ellaOne can be taken up to 120 hours (5 days) after unprotected sex and is often chosen when more time has passed or ovulation may be close.
• Levonorgestrel emergency contraception is effective when taken within 72 hours (3 days) and is often associated with “Plan B–type” searches.

Both treatments are most effective when taken as soon as possible after unprotected sex.
