Yes, chills and diarrhea are very common and normal side effects of a medication abortion.
These symptoms are caused directly by misoprostol, the second medication taken during the process. While misoprostol is primarily taken to cause uterine contractions, it also temporarily affects smooth muscles in other parts of your body, particularly your digestive tract and temperature-regulation system.
What to Expect and How Long It Lasts
-
The Timeline: Chills, diarrhea, nausea, and even a mild low-grade fever usually peak around 1 to 4 hours after taking misoprostol—which is the same window when cramps and bleeding are heaviest.
-
How Long It Should Last: These symptoms are temporary and typically resolve completely within 24 hours after taking the medication.
How to Manage These Side Effects
-
For Diarrhea: Drink plenty of water, clear broths, or electrolyte solutions (like Pedialyte or Gatorade) to prevent dehydration. Over-the-counter anti-diarrheal medication (like Imodium) can be used if necessary, provided you can keep liquids down.
-
For Chills: Wrap up in warm blankets or use a hot water bottle or heating pad on your abdomen or lower back to soothe cramps and manage shivering.
-
For Mild Fever: You can take over-the-counter fever reducers such as ibuprofen or acetaminophen (Tylenol) if they are part of your clinician’s recommended pain management plan.
When to Contact a Doctor
While chills and diarrhea are expected during the first 24 hours, they can occasionally point to a complication if they persist. Contact your healthcare provider if you experience any of the following warning signs:
-
Symptoms Last More Than 24 Hours: If you still have severe diarrhea, nausea, vomiting, or chills more than 24 hours after taking misoprostol, it could be a sign of an infection.
-
High or Persistent Fever: A fever of 100.4°F (38°C) or higher that lasts for more than 4 hours, or any fever that starts after the first 24 hours, requires immediate medical evaluation.
-
Severe Dehydration: Call a doctor if you are throwing up repeatedly, cannot keep fluids down, or have severe diarrhea lasting several hours.
