It is normal for patients to vomit after taking mifepristone as a sign of gastrointestinal reaction to mifepristone. If vomiting occurs within 30-60 minutes of taking mifepristone, the medication is not effective if vomited out. Whether the patient is using it for emergency contraception, or for medication abortion, it will need to be taken again as a refill. In cases of severe gastrointestinal reactions, it is recommended not to take mifepristone on an empty stomach and to choose to take mifepristone half an hour after a meal. The patient’s stomach contents are not completely digested and absorbed, which can reduce the stimulating effect of the drug on the gastrointestinal tract. Before taking it, you can also take drugs to protect the stomach, such as Daxil or Omeprazole, etc. If the nausea and vomiting symptoms are more obvious after use, you can also add these two drugs.
