Description:Objective
To evaluate the association between monotherapy topiramate use in pregnancy and cleft lip with or without cleft palate (CL/P) in the offspring.
Study design
Data from the Slone Epidemiology Center Birth Defects Study (BDS) from 1997–2009 and the National Birth Defects Prevention Study (NBDPS) from 1997–2007 were analyzed. Conditional logistic regression was used to compare first-trimester use of topiramate monotherapy to no antiepileptic drug use during the periconceptional period between mothers of infants with CL/P and mothers of controls for each study separately, and in pooled data.
Results
BDS contained 785 CL/P cases and 6,986 controls; NBDPS contained 2,283 CL/P cases and 8,494 controls. The odds ratios (exact 95% confidence intervals) for the association between topiramate use and CL/P were 10.1 (1.1; 129.2) in BDS, 3.6 (0.7; 20.0) in NBDPS, and 5.4 (1.5; 20.1) in pooled data.
Conclusions
First-trimester use of topiramate may be associated with CL/P.
