What if I get sick after taking my birth control pill?

If you’re taking a combination birth control pill (estrogen + progestin):

  • If you vomit more than 2 hours after taking an active birth control pill, you are still protected from pregnancy.
  • If you vomit within 2 hours of taking an active pill, treat it as a missed pill and take another active pill right away. As long as you don’t throw up again, you are still protected from pregnancy.
  • If you vomit after taking an inactive pill, don’t worry! You are still protected from pregnancy.
  • If you have ongoing vomiting or diarrhea (3 or more watery stools in 24 hours) lasting more than 24 hours, your protection from pregnancy may be reduced. If you can, keep taking your pills at the normal time each day, but you also should use a backup method while you’re ill and for 7 days after your vomiting or diarrhea has stopped.
  • If you’re still not sure what to do if you’re sick after taking a pill, keep taking your pill at the normal time each day and use a backup method until you can talk with a doctor at Nurx or another health care provider.

If you’re taking a progestin-only birth control pill:

  • If you vomit more than 2 hours after taking your pill, you are still protected from pregnancy.
  • If you vomit within 2 hours of taking your pill, take another pill right away. If you don’t take a replacement pill within 3 hours of your normal time, use a backup method for the next 48 hours.
  • If you have ongoing vomiting or diarrhea (3 or more watery stools in 24 hours) lasting more than 24 hours, your protection from pregnancy may be reduced. If you can, keep taking your pills at the normal time each day, but you also should use a backup method while you’re ill and for 2 days after vomiting or diarrhea has stopped.
  • If you are still not sure what to do if you’re sick after taking a pill, keep taking your pill at the normal time each day and use a backup method until you can talk with a doctor at Nurx or another health care provider.
