Mini pill

Also known as the progestogen-only pill or POP

What is it?

The progestogen-only pill is a course of tiny tablets containing the hormone progestogen, which women can take to prevent pregnancy.

You take the pill every day, at the same time, for 28 days, and then begin a new pack of pills without a break.

How does it work?

The hormone in the pill works in several ways to prevent a woman from getting pregnant; firstly it thickens cervical mucous to prevent sperm from being able to reach an egg, secondly it thins the lining of the womb so that if an egg was fertilized it would not be able to implant, and lastly for some women it may stop eggs from being released (ovulation).

How effective is it?

When the pill is taken correctly, which means taking it according to instructions and not taking pills late or missing any, the pill is 99% effective in preventing pregnancy.

What are the advantages?

Being on the pill does not interrupt sex. Other benefits are lighter or no periods, reduced period pain and premenstrual symptoms.

The progestogen-only pill is often suitable for women who can’t take the combined pill.

What are the downsides?

When you start taking the pill you may experience some temporary side effects, such as breast tenderness, spotty skin, headaches and mood changes. Also, you may not have regular bleeds (periods) whilst taking this pill, which some women find annoying or worrying.

Things to bear in mind

The pill is not suitable for everyone, and it is important that the doctor prescribing it to you is aware of your medical history and any other medication you are taking.

Also other medications, such as antibiotics, can make it less effective and an additional method of contraception, like condoms, should be used whilst you are taking them.

Most importantly, the progestogen-only pill does not provide any protection against HIV or sexually transmitted infections like a condom does.

Where can I get it from and how much does it cost?

The progestogen-only pill is available free on the NHS. You can only get it on prescription from a doctor. This can be your GP, another GP who you have registered with for family planning services, or a doctor at a family planning or young person’s clinic.
