Olsalazine Sodium Interactions

Pregnancy & Breastfeeding

8.1 Pregnancy Risk Summary Published data from meta-analyses, cohort studies and case series on the use of mesalamine, the active moiety in DIPENTUM, during pregnancy have not reliably informed an association with mesalamine and major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data ) . There are adverse effects on maternal and fetal outcomes associated with ulcerative colitis in pregnancy (see Clinical Considerations ) . In animal reproduction studies, there were adverse developmental effects observed after oral administration of olsalazine sodium in pregnant rats during organogenesis at doses of 5 to 20 times the maximum recommended human dose (see Data ) . The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-associated maternal and embryo/fetal risk Published data suggest that increased disease activity is associated with the risk of developing adverse pregnancy outcomes in women with ulcerative colitis. Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 g) infants, and small for gestational age at birth. Data Human Data Published data from meta-analyses, cohort studies and case series on the use of mesalamine, the active moiety in DIPENTUM, during early pregnancy (first trimester) and throughout pregnancy have not reliably informed an association of mesalamine and major birth defects, miscarriage, or adverse maternal or fetal outcomes. There is no clear evidence that mesalamine exposure in early pregnancy is associated with an increased risk in major congenital malformations, including cardiac malformations. Published epidemiolog
