In patients with rheumatoid arthritis who hope to conceive, continuing biologic disease-modifying anti-rheumatic drugs at the time of conception could shorten the time to pregnancy. Using biologic disease-modifying anti-rheumatic drugs before pregnancy does not affect abortion, preterm birth, light-for-date, and premature rupture of the membranes.
