Misoprostol (Cytotec) can be used for a variety of conditions. It's FDA approved to lower the risk of stomach ulcers caused by nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (Advil, Motrin) in certain people. Misoprostol (Cytotec) is also commonly used off-label for medical abortion (using prescribed medications to end a pregnancy) and inducing (starting) labor in people who are pregnant.
Reduce the risk of stomach ulcers caused by nonsteroidal anti-inflammatory drugs (NSAIDs) - FDA-approved
Medical abortion - Off-label
Labor induction - Off-label
Misoprostol (Cytotec) is a prostaglandin. It acts like your body's natural prostaglandins, which are chemicals that help protect the stomach to prevent injury and ulcers. Not only do NSAIDs lower the amount of prostaglandins within the stomach area, but the medication itself can cause stomach injury. So people who take NSAIDs have a higher risk of stomach ulcers. That's why certain people who take NSAIDs might also be prescribed misoprostol (Cytotec) to reduce the risk of stomach ulcers.
For people who are using the medication for medical abortion or labor induction, misoprostol (Cytotec) causes the uterus to contract and empty.

Lowers risk of stomach injury and ulcers from NSAIDs
Safe to use in older adults who are at high risk for stomach problems with NSAIDs
Proven safe and effective when used for medical abortions or labor induction
Available as a lower-cost generic
Can cause diarrhea and stomach cramping
Can't be used for ulcer prevention in people who are pregnant
Needs to be taken four times a day with food if used for ulcer prevention
Must be taken at specific time intervals if taken for medical abortion
For ulcer prevention
Make sure to take misoprostol (Cytotec) four times a day with food to lessen your risk of diarrhea. A dosing schedule you could follow, for example, would be to take the medication three times throughout the day with meals, followed by the last dose at bedtime.
Let your provider know if you're having a lot of side effects from misoprostol (Cytotec). Your dose might need to be lowered if you're having a hard time tolerating the usual dose.
If you stop taking NSAIDs, you can also stop taking misoprostol (Cytotec). This is because misoprostol (Cytotec) works to prevent stomach ulcers caused by NSAIDs.
For medical abortion
Instead of swallowing the pill, you'll need to place a certain number of pills either under your tongue or against your cheeks inside your mouth for 30 minutes until they dissolve. To make sure the medication gets fully absorbed, don't eat or drink when the pill is dissolving, but remember to wash it down with water after the 30 minutes is up. Depending on the regimen you use, you might need to repeat the step again.
Expect to have stomach cramps and vaginal bleeding within 1 to 4 hours after taking misoprostol (Cytotec). If you don't have any bleeding after 24 hours of taking the medication, let your provider know, because you might need another dose. Keep in mind that everyone will have a different experience.
For labor induction
The dose of misoprostol (Cytotec) for labor induction is usually lower than that used for ulcer prevention or medical abortion.
You'll either take misoprostol (Cytotec) by mouth or it's placed vaginally by a healthcare provider. Your provider will help decide the best way to induce labor.
Misoprostol (Cytotec) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Misoprostol (Cytotec) shouldn't be used to prevent stomach ulcers in people who are pregnant. Misoprostol (Cytotec) can cause unwanted effects during pregnancy, including pregnancy loss (abortion), premature birth, birth defects, or damage to the uterus. Because of this, your provider will require you to take steps to prevent pregnancy while taking this medication. This might include taking pregnancy tests, birth control, or starting misoprostol (Cytotec) on a specific day after your next period. If you're pregnant and want to prevent stomach ulcers from NSAIDs, talk to your provider about other treatment options that are safer for you and your baby.
However, misoprostol (Cytotec) can be used safely and carefully in people who are pregnant for medical abortion or labor induction. Your provider will discuss with you about how to take the medication safely.
Reduce the risk of stomach ulcers: The typical dose is 200 mcg by mouth four times a day with food.
Medical abortion: The medication is taken by mouth either in combination with mifepristone (Mifeprex) or on its own.
Labor induction: The medication is usually given in the hospital by a provider before labor at lower doses.
Using this medicine with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
