In brief: Probably, but ask OB
Adverse events have not been observed in animal reproduction studies.
Sulfasalazine and sulfapyridine cross the placenta; a potential for kernicterus in the newborn exists.Based on available data, an increase in malformations in the developing fetus has not been observed following maternal use of sulfasalazine. As always, discuss this with both OB and your rheumatogist.Do not stop meds on your own.
