Abortion pills are safe and effective medicines, and most women who use abortion pills will not have problems. However, you should not use abortion pills if:
- Someone is forcing you to end your pregnancy
- You are not sure about wanting to end your pregnancy
- You have an allergy to Mifepristone, Misoprostol, or prostaglandins
- You have one of the following diseases: chronic adrenal failure, hemorrhagic disorders or bleeding disorders, or inherited porphyrias
- You know that you have an ectopic pregnancy (a pregnancy outside the womb)
- You cannot get to a hospital within an hour if needed
- You are alone. You should ask a partner, friend or another trusted person to stay with you while you use the medicines.
Allergic reactions to abortion pills are rare. In a study that looked at 80,000 women who have used Mifepristone-Misoprostol, 6 women (0.008%) had mild allergic reactions after they took mifepristone. All of them received treatment with an oral antihistamine and took the misoprostol with no further problems.
