Allergies to mifepristone and misoprostol pills are rare, and to find out if you are or are not allergic to these medicines, the signs are similar to any other allergic reaction. If you have taken the abortion pills, look out for the signs like:

• Swelling in the throat, face, lips, or tongue
• Itching or rashes (especially hives)
• Breathing issues or tightening of the chest
• Faintness or dizziness

If these symptoms occur after taking the abortion pill, it means you have an allergy and should immediately seek medical attention. 

What if I’ve never taken these pills before?

If you haven't used Mifepristone or Misoprostol before and have no known drug allergies, the likelihood of reacting is quite low. Millions of people use them globally; thus, they are considered safe for most. 

Still, here’s what you can do:

• Check your medical history: If you have had allergies to similar medicines (like prostaglandins) in the past, let your provider know.
• Be a good observer: Monitor how you feel after taking the pills. Side effects like cramping, bleeding, and nausea are expected, but allergic reactions are sudden and severe.
