Pregnancy & Breastfeeding

8.1 Pregnancy Risk Summary Available data from published studies and postmarketing experience with aspirin and extended-release dipyridamole capsules use during pregnancy have not identified a clear association between aspirin and extended-release dipyridamole capsules use and major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data). Aspirin and extended-release dipyridamole capsules contains low-dose aspirin which is an NSAID (see Clinical Considerations). In animal reproduction studies, there were adverse developmental effects with administration of aspirin in rats and rabbits at doses about 66 and 44 times, respectively, the human exposure at the maximum recommended daily dose of aspirin-dipyridamole. Reproduction studies with dipyridamole in mice, rabbits, and rats have revealed no evidence of harm to the fetus up to doses about 25 times the maximum recommended daily human dose of aspirin-dipyridamole. Nonclinical data are suggestive of a possible potentiation of aspirin-related fetal toxicity when combined with dipyridamole (see Data). The estimated 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 Labor and Delivery Aspirin and extended-release dipyridamole capsules, which contains dipyridamole and low-dose aspirin, increases the risk for bleeding [see Warnings and Precautions (5.1)]. Maternal use of high-dose aspirin can result in excessive blood loss at delivery, prolonged gestation, prolonged labor, intracranial hemorrhage in premature infants, low birth weight, stillbirth, and neonatal death.
