Arthrotec contains a combination of diclofenac and misoprostol. Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing substances in the body that cause pain and inflammation.
Misoprostol reduces stomach acid and replaces protective substances in the stomach that are reduced by NSAIDs.
Arthrotec is used to treat osteoarthritis and rheumatoid arthritis in people at high risk for developing stomach or intestinal ulcers.
Arthrotec may also be used for purposes not listed in this medication guide.
Mifeprex is used in a regimen with another prescription medicine called misoprostol, to end an early pregnancy. Early pregnancy means it is 70 days (10 weeks) or less since your last menstrual period began. Mifeprex is not approved for ending pregnancies that are further along. Mifeprex blocks a hormone needed for your pregnancy to continue.
