Tedizolid Pregnancy Warnings

This drug should be used during pregnancy only if the benefit outweighs the risk to the fetus.
-According to some authorities: Use should be avoided.

US FDA pregnancy category: C

Animal studies have revealed evidence of fetal developmental toxicity; such toxicity included reduced fetal weights, increased incidence of costal cartilage anomalies, and increased skeletal variations (including reduced ossification of the sternebrae, vertebrae, and skull) at exposures of 4- to 6-fold the estimated human exposure. The no observed adverse effect levels for fetal toxicity in mice, maternal and fetal toxicity in rats, and rabbits were associated with drug plasma AUC values about equivalent to (mice and rats) or 0.04-fold (rabbits) the drug AUC value associated with the oral human therapeutic dose. There are no controlled data in human pregnancy.

US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
