During a medication abortion, nausea is commonly experienced by women due to one or more reasons. For some women, nausea is severe and lasts longer, while for others it may only be mild and pass quickly (if you were nauseous before the abortion as a result of being pregnant). The good news is that nausea usually passes very quickly after a medication abortion and can be easily treated with over-the-counter medications.

Because your body is undergoing such an unfamiliar, temporary time of change, it is also not unusual that cramping, bleeding and hormone changes associated with a medication abortion will all cause your body to react by making you feel sick to your stomach. While nausea can cause distress due to its unpleasantness, rest assured that nothing is wrong with you this reaction to the medication is simply a part of this process.

Many people also wonder about abortion pill side effects duration  how long symptoms last, what to expect day by day, and when they should start feeling like themselves again. We cover all of that below.

Nausea Can Be a Side Effect of the Abortion Pill

The first medicine, mifepristone, is used to stop an ongoing pregnancy; the second medicine misoprostol causes the uterine contractions necessary for expelling the pregnancy. Although they both work together to provide an effective method of ending early pregnancy, they affect the body in different ways. Being commonly associated with the use of misoprostol, nausea can be due to the abrupt change in hormone levels while receiving mifepristone and misoprostol.

Mifepristone (the first medication)

Mifepristone mainly blocks progesterone which is the hormone that helps support a person during pregnancy. Most people after taking Mifepristone will not experience many (if any) side effects, however if side effects do occur, they should be mild in nature i.e.:

• Light spotting
• Mild cramping
• Fatigue
• Mild Nausea (though less common)

Understanding medical abortion first pill side effects helps set realistic expectations before you begin the process. Most people are surprised by how few symptoms mifepristone alone produces  the more significant physical experience comes with the second medication.

Misoprostol (the second medication)

After taking Mifepristone, Misoprostol is the medication that has an effect on causing the uterus to contract and expel its contents. Most people find that this is when they notice the greatest physical sensations, or effects, due to stronger physical effects including, but not limited to:

• Cramps that come in waves
• Heavy bleeding
• Chills/facial flushing
• Nausea/vomiting
• Diarrhea after using misoprostol (common and temporary)

These are the most commonly reported first abortion pill side effects  and while they can feel intense in the moment, they are temporary and expected as part of a normal medication abortion process.

So why do people feel nauseated when taking misoprostol?

• Cramping may stimulate nausea through affected nerves
• Uterine contractions can affect nearby areas of the body resulting in nausea
• Change in hormones dropping rapidly as part of the process

Misoprostol may irritate the gastrointestinal tract (gastrointestinal irritability may cause nausea, vomiting, and diarrhea) it is known to work on smooth muscle in several areas not just the uterus

If you were previously experiencing nausea due to being pregnant, and taking misoprostol, you may have been more likely to feel nauseated. Most individuals will not experience any long-term, or dangerous, side effects of abortion pill long term associated with their nausea; it will just be uncomfortable and last for a short period of time.

When Does Nausea Start After Taking Abortion Pills?

When you take mifepristone tablet, it’ll usually take several hours after taking misoprostol for nausea to start, which is different for each person. After taking mifepristone, many people feel normal (or almost normal) until they notice nausea starting to develop four [or more] hours after misoprostol. Nausea then reaches its maximum level at about the same time as cramping from the contractions of your uterus get really intense.

While vomiting from nausea can happen, most people will simply begin feeling sick to their stomachs after taking misoprostol prior to losing the pregnancy. While some may have one or two instances of vomiting as a result of their nausea, both are considered within what’s considered normal.

How Long Does Nausea Last During a Medication Abortion?

The most people typically has periodic instances of feeling nauseous from about the same time frame as when they begin taking misoprostol until the time they stop cramping from their body having gone through the process of losing the baby.

To summarize the difference between experiencing vomiting and experiencing nausea after your pregnancy has ended, think of the vomit from nausea coming at the peak of your cramping, as opposed to nausea happening throughout your cramping.

Understanding abortion pill side effects duration is important for planning your recovery. For most people, the most intense symptoms  nausea, cramping, and heavy bleeding  resolve within the first 24 hours, with lighter symptoms continuing for a short period afterward.

If you had pregnancy nausea before

If you had morning sickness while you were pregnant, there’s a good chance you will still have instances of nausea up to a few days after your pregnancy has passed (although the amount of time it takes for you to start feeling normal will depend significantly on how long it took you to have experienced morning sickness).

What about diarrhea?

People who take misoprostol will usually also experience some nausea along with diarrhea. Diarrhea often lasts a short time (under 24 hours) and can be treated by drinking fluids and getting adequate rest.

Normal vs. Contact a Provider

Below is a quick guide for determining whether or not you need to check in with your doctor based on what you might be experiencing as a reason for communicating that there may be some issues regarding misoprostol.

Normal	Contact a Provider
Mild-moderate nausea for a few hours.	Nausea lasting longer than 24 hours.
Vomiting only once or twice.	Vomiting many times/repeatedly or not able to keep down fluids.
Temporary diarrhea after misoprostol (usually).	Severe diarrhea longer than 24 hrs.
Cramping feeling while feeling queasy.	Signs of dehydration (e.g., dizziness, dry mouth, dark urine, little urination).
Gradual improvement as cramps go away.	Worsening instead of improving.
Wondering if “when vomiting after misoprostol, does it still work?” otherwise stable.	Vomiting shortly after ingesting the medication and unsure if absorbed.

If you are ever uncertain whether or not to communicate with your provider, please know that you can always reach out, and part of medical care is providing reassurance.

How to Treat Nausea During an Abortion

Your main priority should be your physical comfort and staying hydrated. If you’re feeling nauseous, there’s no need to try and “push through” the feeling. There are several things you can do that may help relieve the nausea quickly.

1) Rest and reduce movement

Movement may make your nausea worse. If you are feeling nauseous, lie down on your side or back, and have your head elevated (slightly) if you find that it feels better this way.

2) Take slow sips (don’t chug)

You may find small sips of water much easier to tolerate than large gulps of water. Some suggested beverages are:

• Room temperature water
• Electrolyte beverages
• Ginger tea
• Peppermint tea

If you are having vomiting or diarrhea, drinking fluids is much more important than eating food at this time.

3) Try simple foods if tolerated

If you are having some food, try selecting bland, small portioned foods from the following:

• Crackers
• Toast
• Rice
• Bananas
• Applesauce

Do not eat greasy, spicy, heavy foods until you have settled your stomach.

4) Use nausea medication if you have it

If the provider has recommended an anti-nausea medication, take it before you take the Misoprostol medication to see if it will help reduce the nausea from increasing.

5) Support your body during cramping

Cramping is also a trigger of nausea. You may find any of the following helpful:

• Heating pad on your abdomen
• Deep slow breathing (in through your nose and out through your mouth)
• Calm environment (dim lights, little noise)

For complete guidance on managing physical discomfort, read our full guide on abortion pain management.

6) Don’t ignore dehydration signs

If you are unable to keep fluids down due to nausea, vomiting, or diarrhea, you will want to reach out to your provider for assistance.

When to Contact a Provider

It is common for someone to experience nausea; however, when suffering from severe, long-lasting, or worsening nausea, you should reach out to someone for assistance. You should follow up with a health care professional if any of the following occurs:

• Your nausea persists longer than twenty-four hours
• Your vomiting is frequent or you cannot consume fluids
• You exhibit symptoms of dehydration (lightheadedness, dry mouth, very dark colored urine, or very minimal urination)
• You are weak and the weakness is continuing to worsen
• Your diarrhea following misoprostol is severe and/or has continued for over twenty-four hours
• You vomited soon after taking your medication and are concerned about how much of it may have been absorbed
• You are feeling anxious and have questions about your situation, and would like reassurance and guidance as part of your care plan

You can review signs to go to the emergency room after taking the abortion pill to help determine when symptoms require urgent care versus routine follow-up.

As a general rule, if your symptoms are “too much”, last too long, or prevent you from being able to stay hydrated, please seek medical attention. You deserve to feel safe and have access to information about your condition.

What About Mental Side Effects of the Abortion Pill?

What About Abortion Pill Side Effects and Hair Loss?

Some people report noticing increased hair shedding in the weeks following a medication abortion and wonder about abortion pill side effects hair loss. This is typically related to the rapid drop in pregnancy hormones  particularly estrogen and progesterone  that occurs after the pregnancy ends, rather than a direct effect of mifepristone or misoprostol themselves. This type of hormonal hair shedding, known clinically as telogen effluvium, is temporary and resolves on its own as hormone levels stabilize. If hair loss is persistent or severe, consult your provider.
