Managing Rheumatoid Arthritis During Pregnancy and Breastfeeding

Rheumatoid arthritis (RA) is a kind of arthritis that causes joint pain, stiffness, swelling, and decreased range of motion. The small joints in the hands and feet are most frequently affected. It is an autoimmune condition, meaning the immune system doesn’t work the way it should and attacks the lining of the joints. Women are three times more likely than men to develop RA, and it most commonly begins between ages 30-60, so can impact a person’s childbearing years.

RA can cause complications in pregnancy, although if RA is well controlled for 3-6 months before becoming pregnant, the chance for complications tends to be lower than it is for people with more active RA. Untreated active RA increases the chance for complications such as preterm birth, preeclampsia (a pregnancy-related condition characterized by a dangerous rise in blood pressure and problems with kidney function), and low birth weight. Because pregnancies are more successful when RA is well controlled, staying on a medication that works for you is important for your health and the health of the pregnancy – but there are also some medications that should be avoided. Be sure to talk to your healthcare provider about all of your pregnancy and breastfeeding questions.

[People] who have uncontrolled rheumatoid arthritis may be at increased risk of complications such as preterm birth and babies that are small for their gestational age. This may increase the likelihood that the baby requires more medical care early in life.
