In one study, rats were given oral sodium oxybate throughout pregnancy and lactation. This resulted in increased stillbirths, decreased offspring survival after birth, and decreased body weight gain.[15] In another study, pregnant rats and pregnant rabbits were given oral sodium oxybate during organogenesis. This resulted in no evidence of adverse effects on fetal development.[15] As such, sodium oxybate should be used in pregnancy only if the benefit outweighs the risk for the fetus.
