Can having diarrhea make the pill less effective?
updated over 3 years ago

Having “loose” poop every now and then probably won’t affect how well your pill works, but severe diarrhea (eg. if you have it several times in one day) might. If you rely on the pill for birth control and you have severe diarrhea, it’s a good idea to use a backup method like condoms if you have sex while you’re sick or in the 7 days after you recover.

Still not working?

Common things like forgetting to take a pill or throwing up right after taking one are part of why the pill has a 9% failure rate. If that sounds too risky to you, you can double up with condoms or switch to a lower maintenance method.

Try a different method
