Morning-After Pill vs Regular Pill: What's the Difference?

Understanding the morning after vs normal pill distinction can help you know which option you need and, importantly, what to do after taking emergency contraception.

What is the regular contraceptive pill?

The regular contraceptive pill is an ongoing form of hormonal contraception. There are two main types available in the UK: the combined pill and the progestogen-only pill, often called the mini pill.

The combined pill contains oestrogen and progestogen and primarily works by preventing ovulation. The mini pill contains progestogen only and also helps prevent pregnancy, although exactly how it works can vary depending on the type.

Both are designed to be taken regularly rather than only after intercourse.

When used perfectly, both the combined and progestogen-only pill are more than 99% effective. With typical use, which accounts for things such as forgetting a pill, they are around 91% effective.

What is the morning-after pill?

The morning-after pill is a type of emergency contraception. Rather than being taken continuously, it's used after unprotected sex or when there is a risk that your regular contraception hasn't worked.

There are two main types of emergency contraceptive pill used in the UK:

• Levonorgestrel, which needs to be taken within 72 hours (3 days) of unprotected sex.
• Ulipristal acetate, which needs to be taken within 120 hours (5 days) of unprotected sex.

The sooner you seek emergency contraception, the better. The most effective form of emergency contraception is actually the copper IUD (coil), rather than the morning-after pill.

Despite its name, you therefore don't have to wait until the "morning after" to take emergency contraception.

Morning-after pill vs regular pill: what's the difference?

The biggest difference is when and why they're used.

Your regular contraceptive pill is taken on an ongoing basis to prevent pregnancy before sex takes place. The morning-after pill is intended for situations where unprotected sex has already happened or your usual contraception may have failed, such as after certain missed pills.

They also contain different medicines or doses and are taken differently. You shouldn't take a morning-after pill every day in place of your normal contraceptive pill.

It's therefore better to think of them as two separate forms of contraception with different purposes rather than interchangeable versions of the same pill.

Can you use the morning-after pill as normal contraception?

The morning-after pill should not be used as a replacement for a regular method of contraception.

It is designed to provide emergency protection following a particular episode of unprotected sex or contraceptive failure. It also does not provide ongoing protection against pregnancy from sex later in your cycle.

If you find that you need emergency contraception regularly, it may be worth discussing your contraception with a healthcare professional. A regular method such as the combined pill, mini pill, implant, injection, patch, ring, IUD or IUS may provide a more appropriate way to prevent pregnancy on an ongoing basis.

Can you take the morning-after pill if you're already on the pill?

Yes. You may be advised to use emergency contraception if you've missed contraceptive pills or there is another reason your regular contraception may not have protected you.

However, what you should do afterwards depends on which emergency contraceptive pill you take and which regular contraception you use.

This distinction is particularly important because ulipristal acetate can interact with hormonal contraception. After taking it, you should usually wait 5 days before restarting your regular hormonal contraception, and use additional protection such as condoms in the meantime and until your pill is working again (FSRH).

Because the correct advice varies, speak to the pharmacist, doctor or sexual health professional providing your emergency contraception and follow the instructions you're given rather than simply restarting your pill without checking.

Which pill do I need?

If you're looking for ongoing contraception, the combined pill or mini pill may be suitable depending on your health, medical history and personal circumstances.

If you've already had unprotected sex, missed contraception or believe your contraception has failed, seek advice about emergency contraception as soon as possible. The appropriate option can depend on when you had sex, the contraception you normally use, other medicines you take and your individual circumstances.
