What if I vomit or have diarrhea after taking the progestin only pill?
If a woman vomits within 2 hours of taking the pill she should take another pill as soon as possible if she feels well enough. As long as she is not sick again, the efficacy of the pill will not be affected. She should continue to take the following pills on the next day at the usual hour. For situations like this she can have a back-up package to use as needed, as this will prevent disrupting the continuity of pills in her current package.
If a woman has had diarrhea for 24 hours then she should consider that day a missed pill day and follow the instructions for missed pills.
If she continues to be sick, she should continue the pill but use a barrier method like condoms if she has sexual intercourse. She can stop using condoms once she is well and 48 hours have passed since the last episode of diarrhea or vomiting.
