What to do if you’re sick or have diarrhoea when taking the progestogen-only pill

If you’re sick or have diarrhoea when taking the progestogen-only pill (mini pill), what you need to do will depend on:

  • how much time has passed
  • whether you take a traditional progestogen-only pill, desogestrel pill or drospirenone pill

If you’re not sure what type of pill you’re taking, check the pack to see if it contains desogestrel or drospirenone, a type of progestogen.

The progestogen-only pill may not work if:

  • you vomit within 2 hours of taking a traditional progestogen-only pill
  • you vomit within 3 to 4 hours of taking a desogestrel or drospirenone pill
  • you have severe watery diarrhoea

You may need emergency contraception. Speak to a pharmacist, sexual health clinic or GP or call 111, as the progestogen-only pill can affect how some types of emergency contraception work.

Talk to a pharmacist or check the information leaflet that comes with your progestogen-only pill to find out what to do about taking your pills.
