Misoprostol chills usually last a few hours and should generally improve within 24 hours after taking the medication. Chills, shivering, and feeling temporarily cold are common short-term side effects of misoprostol and do not automatically mean that something is wrong.
Some people experience only mild chills, while others may shake noticeably for a short period. The symptoms often occur around the same time as cramping and bleeding and gradually improve as the strongest effects of misoprostol wear off.
However, chills that continue beyond 24 hours—especially when accompanied by a persistent fever, worsening abdominal pain, weakness, or feeling increasingly ill—should be discussed with a healthcare provider.
Why Does Misoprostol Cause Chills?
Misoprostol is a prostaglandin medication. In addition to causing the uterus to contract, it can temporarily affect the body’s temperature-regulation system.
This is why misoprostol can cause:
- Chills
- Shivering
- Feeling unusually cold
- Sweating
- A temporary rise in temperature
- Flushing
These effects can occur even when there is no infection.
Chills are particularly common after misoprostol and may begin around the same time that cramping, bleeding, nausea, or diarrhea starts.
For a broader explanation, read Is it normal to have chills after taking abortion pills?.
How Soon After Misoprostol Can Chills Start?
Chills may begin relatively soon after taking misoprostol.
The exact timing varies from person to person. Some patients notice shaking or feeling cold within the first few hours, while others experience little or no temperature-related symptoms at all.
Chills may occur together with:
- Increasing cramps
- Vaginal bleeding
- Passing blood clots
- Nausea
- Diarrhea
- Temporary fever
- Fatigue
The fact that someone experiences strong chills does not necessarily mean that the medication is working better than it would for someone who has no chills.
Abortion-pill experiences can vary substantially between individuals.
How Long Do Chills Last After Misoprostol?
For most people who experience them, misoprostol-related chills are temporary and last several hours rather than several days.
They often improve as the most intense medication effects begin to settle.
A general pattern may look like this:
First few hours: Chills or shivering may begin as misoprostol starts producing stronger physical effects.
Several hours later: Chills commonly become less intense as cramping and other medication effects progress.
Within 24 hours: Misoprostol-related chills should generally have significantly improved or stopped.
There is no exact number of hours that applies to everyone.
Are Severe Chills Normal After Misoprostol?
Strong shivering can occur with misoprostol and can feel surprisingly intense.
Someone may shake enough that their teeth chatter or they need several blankets. This can still be a medication side effect, particularly if it begins soon after taking misoprostol and improves over the following hours.
However, severe chills deserve more attention if they:
- Continue rather than improving
- Begin long after the misoprostol dose
- Occur with persistent fever
- Are accompanied by worsening abdominal pain
- Occur with fainting or severe weakness
- Are accompanied by a generally worsening condition

How Can I Make Misoprostol Chills More Comfortable?
Because ordinary misoprostol chills are usually temporary, treatment is mainly focused on comfort while the medication effects pass.
You can try:
- Use Warm Blankets: Dress comfortably and use blankets if you feel cold.
- Stay Hydrated: Drink water or another nonalcoholic beverage as tolerated.
- Rest Somewhere Comfortable: You do not have to remain in one particular position, but resting can make chills and cramping easier to manage.
- Keep the Room Comfortable: A comfortable room temperature can help if you alternate between chills and feeling hot.
- Follow Your Pain-Medication Instructions: If your clinician recommended ibuprofen or another medication, use it according to their instructions.
Avoid overheating yourself with extremely hot baths or excessive external heat if you are dizzy or weak.
Can I Use a Heating Pad When I Have Chills?
A heating pad can be helpful for abdominal or back cramps and may also make you feel more comfortable while experiencing chills.
Use it at a comfortable temperature rather than placing extremely high heat directly against your skin.
A heating pad does not interfere with misoprostol or prevent the medication from working.
You can read more about using heat for abortion-pill cramps.
Are Chills and Diarrhea Normal Together?
Yes. Misoprostol can cause both chills and diarrhea because its effects are not limited entirely to the uterus.
Temporary gastrointestinal symptoms can include:
- Diarrhea
- Nausea
- Vomiting
- Stomach discomfort
Having diarrhea and chills together shortly after misoprostol can therefore be an expected medication reaction.
The main concern is maintaining hydration, especially if you also vomit or have significant diarrhea.
Learn more in our guide on whether chills and diarrhea are normal during abortion.
What Is the Difference Between Normal Chills and an Infection?
Timing is important.
Chills that begin soon after misoprostol and resolve within several hours are generally more consistent with a medication side effect.
Infection becomes more concerning when symptoms persist or worsen rather than gradually improving.
Contact your healthcare provider if you have:
- Chills continuing more than 24 hours after misoprostol
- A fever of 100.4°F (38°C) or higher that persists or occurs more than 24 hours after misoprostol
- Increasing rather than improving abdominal or pelvic pain
- Feeling progressively weaker or more ill
- Foul-smelling vaginal discharge
- Persistent vomiting or inability to stay hydrated
- Other symptoms your healthcare provider has identified as warning signs
A temporary temperature increase soon after misoprostol can occur as a medication effect, so fever does not automatically mean infection.
However, fever that persists or develops later deserves medical evaluation.

Should I Take My Temperature During Misoprostol Chills?
If you feel extremely hot, unusually cold, or significantly unwell, checking your temperature can provide useful information.
Write down:
- Your temperature
- What time you measured it
- When you took misoprostol
- Whether the temperature is rising or falling
- What other symptoms you have
This information can help your healthcare provider determine whether you are experiencing a temporary medication effect or need further evaluation.
Can Dehydration Make Chills Feel Worse?
Dehydration can contribute to weakness, dizziness, headache, and feeling generally unwell.
Misoprostol may cause diarrhea or vomiting in addition to bleeding, so drinking fluids is important.
You do not need to force large amounts of water at once. If your stomach is unsettled, try small, frequent sips.
Water, electrolyte drinks, juice, broth, and other nonalcoholic drinks you tolerate can help maintain hydration.
Read more about dehydration during the abortion-pill process.
Do Chills Mean Misoprostol Is Working?
Chills can indicate that your body is responding to misoprostol, but chills themselves are not a reliable way to determine whether the abortion was successful.
Some people experience strong chills. Others have none.
Likewise, the intensity of:
- Chills
- Nausea
- Diarrhea
- Cramping
- Other side effects
does not necessarily predict whether medication abortion will be successful.
Bleeding patterns, changes in pregnancy symptoms, follow-up testing, and your healthcare provider’s recommended follow-up are more useful for confirming the outcome.
What If I Have No Chills at All?
That can also be completely normal.
You do not need to experience chills for misoprostol to work.
Different people react differently to the medication. One person may experience chills and diarrhea while another mainly experiences cramping and bleeding.
Do not take additional medication simply because you did not develop chills.
Follow the regimen prescribed by your healthcare provider.
When Should I Contact a Healthcare Provider?
Contact your abortion provider if your chills do not improve as expected or if you are unsure whether your symptoms are normal.
Seek urgent medical evaluation for symptoms such as:
- Fainting or difficulty staying conscious
- Severe or worsening abdominal or pelvic pain
- Difficulty breathing
- Severe weakness
- Inability to keep fluids down
- Persistent fever or chills more than 24 hours after misoprostol
- Bleeding that soaks two full-size pads per hour for two consecutive hours
- Any other emergency symptom your healthcare provider has instructed you to watch for
The combination of your symptoms and their timing matters more than chills alone.
