Diarrhea can significantly impact the effectiveness of birth control pills, as even one episode of diarrhea can slightly increase the risk of becoming pregnant. Oral contraceptives work by changing hormone levels, which prevents ovulating and preventing pregnancy. The pill is usually over 99 percent effective, but health authorities generally do not recommend re-dosing pills based on how long you have had diarrhea. Instead, they often recommend using backup contraception.
Chronic diarrhea can also impede absorption, and the Mayo Clinic advises that if you’ve had serious diarrhea or vomiting for two or more days, act as though you’ve missed a dose. If you continue to experience diarrhea and for seven continuous days after it has resolved, use backup contraception. If you are on your last week of birth control pills, finish the week of pills, and omit the hormone.
CDC guidelines suggest that if you have vomiting or severe diarrhea for less than 48 hours (2 days) after taking a dose, you generally don’t need to repeat the dose. However, if you have diarrhea for more than 24 hours, keep taking the pill as normal. Use another type of contraception, such as condoms, until 7 days after taking the pill without being sick.
Diarrhea is not a concern if you only have diarrhea in the morning, but if you continue to be sick or have severe diarrhea, your protection against pregnancy may be compromised. One loose stool after one pill won’t affect their failure rate. Very severe diarrhea may also mean that the pill does not work properly.
If you’re sick or have diarrhea when taking the progestogen-only pill (mini pill), what you need to do depends on how much time has passed. Hormonal birth control methods, like the pill or patch, can cause changes in bowel regularity that range from constipation to diarrhea.

Does diarrhea flush out birth control?
Using laxatives, which cause you to have a bowel movement (poop), may make your birth control pills less effective. This is because your body doesn’t have time to fully absorb the pill. Vomiting or having diarrhea for more than 48 hours (2 days) can also lower the effectiveness of your pill. If you take your pill and vomit or have excessive diarrhea within 48 hours after taking it, you should treat it as a missed pill. You can take our missed pill quiz to get back on track. Use condoms as a backup method for the next 7 days to fully protect yourself from pregnancy.
However, laxatives won’t affect some other forms of birth control, like the IUD and the implant. So if you use laxatives regularly, ask your nurse or doctor about switching to another method of birth control.
What cancels out the pill?
Anti-Seizure Drugs Some of these medications increase the breakdown of the hormones in birth control pills. That could make them less effective. These drugs include: Carbamazepine (Carbatrol, Epitol, Equetro, Tegretol)
It’s a question you hear your doctor ask every time they prescribe medicine: What other drugs do you take? They are not just curious. Some meds don’t work well if you take them together. The same thing is true of birth control that contains hormones. If you want it to work right, you need to avoid certain medications.
The pill and some other types of birth control like the patch, ring, or injections usually contain the female sex hormones estrogen and progestin. They stop eggs from leaving the ovaries, so you won’t get pregnant. But some meds won’t let the hormones do their job. If you take them at the same time as your birth control, you may not have the protection you think you do.
For the most part, you don’t have to worry about taking these drugs. Doctors prescribe them to treat all kinds of infections caused by bacteria, like pneumonia, acne, and urinary tract infections ( UTIs ). Common antibiotics include penicillin and amoxicillin.
Will a pill still work if you poop after taking it?
Your meds are mainly absorbed through your stomach into the bloodstream.
This is usually in the first few hours after taking them.
The time you go to the toilet does not affect this at all.
The only exception might be if you are very ill and have severe diarrhoea. This would be a reason to talk to your doctor in case the meds are not being properly absorbed.
How much diarrhea makes birth control ineffective?
If your diarrhea continues for more than 48 hours, you may not be protected against pregnancy. Use a backup birth control method like a condom or diaphragm.
