Mifepristone Dosage Guidelines

The dosage guidelines for mifepristone (Mifeprex®, Korlym™) are the same for every woman using the drug to terminate a pregnancy that is seven weeks along or less. This abortion pill is given as a one-time dose of 600 mg (three tablets). The dose is given in a healthcare setting, such as a healthcare provider's office or a clinic.
Two days after taking mifepristone, you will need to return to your healthcare provider's office to see if the abortion was successful. If you are still pregnant, you will be given 400 mcg of misoprostol (Cytotec®), which works by causing uterine contractions to push out the products of conception.
You will need to return to your healthcare provider's office approximately two weeks after taking mifepristone to see if the abortion is complete. If you are still pregnant, your healthcare provider will talk to you about other options for ending your pregnancy, including a surgical abortion.
When used to treat hyperglycemia (high blood sugar levels) due to high cortisol levels in people with Cushing's syndrome, the dosage guidelines will be different. For this use, mifepristone is usually taken once a day.
