Pregnancy-Lactation
Pregnancy
Available data have not suggested increased risk for major birth defects following exposure to varenicline in pregnancy, compared with women who smoke; smoking during pregnancy causes increased risks of orofacial clefts, premature rupture of membranes, placenta previa, placental abruption, ectopic pregnancy, fetal growth restriction and low birth weight, stillbirth, preterm delivery and shortened gestation, neonatal death, sudden infant death syndrome and reduction of lung function in infants; it is not known whether quitting smoking with varenicline during pregnancy reduces these risks
Lactation
Because there are no data on presence of varenicline in human milk and effects on breastfed infant, breastfeeding women should monitor their infant for seizures and excessive vomiting, which are adverse reactions that have occurred in adults that may be clinically relevant in breastfeeding infants
Interactions
Increased incidence of adverse effects (nausea, vomiting) w/ transdermal nicotine. Increased exposure w/ cimetidine.

Mode of Action
Varenicline Tartrate is a partial neuronal alpha 2 beta 2 nicotinic acetylcholine receptor agonist. It works as a smoking cessation aid by preventing nicotine stimulation of mesolimbic dopamine system. It also stimulates dopamine activity but to a much lesser extent than nicotine does, resulting in reduced craving and withdrawal symptoms.
