Pregnant Women: There is no safety data for exposure to tegoprazan in pregnant women. In an embryo-fetal development study, short supernumerary cervical ribs were observed with a higher incidence in rats. Therefore K-CAB is contraindicated during pregnancy.
Nursing Mothers: As it is not known whether tegoprazan is excreted into human milk, discontinue nursing while taking K-CAB. Excretion of tegoprazan into milk has been reported in rats.
