There are several ways to jumpstart the labor process if things don't seem to be getting going on their own. If your healthcare practitioner suggests a Foley balloon induction, what does that mean — and should you do it?

Inducing labor with a Foley bulb or Foley balloon is a safe, simple method that can be a good choice for women who'd like to try avoiding induction drugs or those who aren't able to use them.

Here's how the procedure works and what it feels like, plus a look at the benefits and potential risks.

Key Takeaways
  • A Foley bulb is a simple way to help your cervix open. This small catheter is inserted into the cervix and inflated with a saline solution so it presses gently on the cervical opening, encouraging it to soften and dilate — sometimes enough to get contractions started.
  • It can be a good option if you want to avoid (or limit) induction drugs. A Foley balloon may be used on its own or alongside medications like misoprostol or Pitocin, and it's often recommended for moms who prefer a drug-free approach or who've had a previous C-section.
  • Insertion can be uncomfortable, but it's usually brief — and the method is generally safe. While some moms find placement crampy or painful, the discomfort tends to pass quickly. For many, the Foley bulb is an effective, low-risk way to help get labor moving.

What is a Foley bulb or Foley balloon?

A Foley bulb or Foley balloon is a catheter-like device that can help the cervix soften and open when labor needs to be induced.

The catheter is inserted into the cervix and filled with a saline solution. The saline solution causes the catheter to inflate like a balloon, putting pressure on the cervix to help it dilate.

What is a Foley bulb induction?

If your cervix hasn't started to dilate on its own when you're ready to be induced, your practitioner might start the dilation process with a Foley bulb.

In some cases, dilating your cervix with the Foley bulb is enough to trigger contractions and get the labor process started. In others, your practitioner might try to speed things up by using a Foley bulb along with a synthetic hormone like misoprostol or Pitocin.

"It got me to a 4 from a 0 so I'll call it a win," says What to Expect Community mom CB0103. "I didn't need any pain medication and was able to walk around just fine."

Why your doctor might suggest a Foley bulb induction

There are a few different reasons why your practitioner might recommend using a Foley bulb for induction:

  • You need to be induced but your cervix isn't dilated. Usually your cervix will begin opening naturally once your body is ready to go into labor. But if it hasn't shown any signs of dilating, your doctor can get the ripening process started with a Foley bulb, synthetic hormones, or a combination of the two.
  • You want to try a drug-free induction method. Sometimes a Foley bulb alone can be enough to jumpstart labor without the use of drugs or hormones.
  • You've had a C-section. Foley bulbs are a safer way to induce labor than certain medications for women who've previously had a C-section, since some drugs can increase the risk of complications.
  • You want a shot at a faster labor. Research shows that using a Foley bulb in combination with misoprostol or synthetic oxytocin (Pitocin) may shorten labor compared to using misoprostol or a Foley bulb alone.

"I would definitely do it again if I have a stubborn baby who just needs a little nudge to get going!" says Community member Rosegate29.

What happens during a Foley bulb induction?

If you need to be induced, one option your practitioner may discuss with you is the Foley bulb. Here's what happens during the procedure:

  1. You'll lie on an exam table and place your feet in stirrups, similar to a routine gynecological exam. Your practitioner will use a speculum to check your cervix and apply an iodine solution to clean the area and reduce the risk of infection.
  2. Once your cervix is clean, your practitioner will insert the tip of the Foley bulb into your cervix and inflate the bulb with about an ounce of saline solution.
  3. Your practitioner will tie off the catheter just outside your vagina to keep the saline from leaking out, then tuck the end of the catheter into your vagina with a gauze pad.
  4. In some cases, you might also receive a cervical-ripening drug like misoprostol.
  5. Then you'll wait. The goal is for the inflated Foley bulb to put enough pressure on your cervix to encourage it to dilate and get labor under way, which could take 12 hours or more. The bulb might fall out if your cervix dilates enough, though your provider might also remove it if you've only dilated a few centimeters.
  6. How far you've dilated after the Foley bulb falls out or is removed determines what comes next. Often a Foley bulb — alone or with cervical ripening drugs — is enough to start contractions. But if you haven't begun contracting, your provider might opt to strip or rupture your membranes or administer a drug like Pitocin.

"I had a Foley balloon with my first and was induced with Pitocin too," says Community mom bayansharaka. "It wasn't scary or painful. It was just a long process."

Is a Foley bulb induction painful?

Having a Foley bulb inserted can be pretty uncomfortable and even quite painful for some women, but others report little or no pain. If you do experience pain, it usually doesn't last long (though everyone is different).

  • "It took a second to insert and I felt nothing," says Community mom SunflowerMazes-sheherhers. "And I hate Pap smears and cervical checks. I'm very sensitive, so I was shocked."
  • "I was induced with a foley balloon with my first," says Community member bmmomma14. "It wasn't bad! It was crampy and uncomfortable, but manageable."

Other moms find it more painful.

  • "Honestly the insertion was the worst part, and it was relatively quick!" says Community mom @ABaby22Fg.
  • "Some people say it doesn't bother them at all but mine hurt so bad that I cried until they gave me an epidural," says Community mom em19902.

Once the balloon is in, it usually just feels like a super tampon. Your practitioner may suggest giving you nitrous oxide (laughing gas) to make the insertion process more comfortable.

The benefits of being induced with a Foley bulb

There are several potential benefits to a Foley bulb induction:

  • A Foley balloon can be used with or without medication. Prefer to try a drug-free induction method? A Foley bulb alone may be enough to ripen your cervix and get labor started.
  • A Foley bulb might carry fewer risks than some drug-based induction methods. Certain medications can overstimulate the uterus, which may lead to complications.
  • It's considered a safer option if you've previously had a C-section. Cervical-ripening drugs can raise the risk of complications if you've had a prior C-section, but Foley bulbs typically don't.
  • It may help speed up your labor when used with medications. When combined with misoprostol, a Foley bulb may shorten labor compared with using either method alone.

"Overall I think it was a really nice way to be induced — no medicine," says Community member wife-mum-doula. "I had my baby at 11:58 the morning after it was put in. It did the trick!"

The risks of a Foley bulb induction

A Foley balloon is generally a safe and effective way to induce labor. Still, there are a few drawbacks to consider:

  • The insertion process can be uncomfortable. Fortunately, most women don't find it extremely painful, and any discomfort usually passes quickly. Your practitioner may offer medication to help if needed. "I struggled to complete the Foley balloon placement without any pain meds, so they offered me fentanyl," says Community mom rachw01. "It was incredibly helpful and my baby came out completely healthy."
  • It's not foolproof. A Foley bulb — whether used alone or with cervical-ripening drugs — doesn't always cause a woman's cervix to dilate or start labor.
  • It can cause bleeding in women with low-lying placentas. If your placenta is low-lying, your practitioner will determine whether a Foley bulb induction is a safe choice.
  • It may lengthen labor if left in place too long. Research has found that keeping a Foley balloon in the cervix for 7 hours or more may be associated with significantly longer labor — up to 11 ½ hours longer (about a 37% increase). Patients considering a Foley bulb induction should be informed about the possibility of a longer labor and the potential complications associated with it.

Other methods of inducing labor

A Foley bulb is just one way to induce labor. There are other induction methods your practitioner may recommend, including:

  • Cervical-ripening medications such as misoprostol
  • Membrane stripping or rupturing to help your water break
  • Pitocin, a synthetic form of oxytocin that triggers contractions

A Foley balloon can be a beneficial tool for labor induction, especially for women who want to try a drug-free option or who have previously had a C-section. But you may not know whether you'll actually need to be induced until close to your due date— or even once you're already in the delivery room.
