What is the progestogen-only pill?

  • The progestogen-only pill (mini pill) is a type of hormonal contraception. Progestogen is a hormone that works in a similar way to progesterone.
  • The progestogen-only pill prevents pregnancy by stopping the ovaries releasing an egg each month.
  • The progestogen-only pill is not suitable for everyone.
  • It’s over 99% effective if you use it correctly all the time. If not used correctly, for example missing a pill, it’s less effective.
  • When you stop taking the progestogen-only pill, it usually takes about 1 month for your chance of getting pregnant to return to how it was before.
  • The progestogen-only pill may help with painful or heavy periods and endometriosis.
  • You can compare different methods, including how well they work and side effects, when choosing a method of contraception.
Information:

The progestogen-only pill does not stop you getting or passing on sexually transmitted infections (STIs). Use a condom every time you have sex to protect you and your partner against STIs, including HIV.
