Does the use of nicotine replacement therapy during pregnancy affect pregnancy outcomes?

Objectives: Although nicotine replacement therapies (NRT) may assist with smoking cessation, little is known about the safety of NRT use during pregnancy. Our purpose was two-fold: to determine characteristics of women prescribed or recommended NRT during pregnancy and to investigate whether NRT prescription/recommendation was associated with adverse pregnancy outcomes using data from the 2004 Pregnancy Risk Assessment Monitoring System.

Methods: Smoking and NRT referral was self-reported by 5,716 women.
