Varenicline Levels and Effects while Breastfeeding
Summary of Use during Lactation
Varenicline is a partial nicotine agonist used to assist smoking cessation. One researcher points out that based on animal data on nicotine, varenicline might interfere with normal infant lung development and recommends against its use in nursing mothers.[1] Because no information is available on the use of varenicline during breastfeeding, an alternate drug is preferred, especially while nursing a newborn or preterm infant.
