Olsalazine Pregnancy Warnings

Animal studies showed fetal developmental toxicity (reduced fetal weights, retarded ossifications, immaturity of fetal visceral organs) when given during organogenesis at doses 5 to 20 times the human dose. There are no controlled data in human pregnancy.

AU TGA pregnancy category C: Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human fetus or neonate without causing malformations. These effects may be reversible. Accompanying texts should be consulted for further details.

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.

This drug should be used during pregnancy only if the benefit outweighs the risk to the fetus.

AU TGA pregnancy category: C
US FDA pregnancy category: C
