Droperidol Pregnancy Warnings

Droperidol should be used during pregnancy only if the benefit outweighs the risk.

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

Animal studies have failed to reveal evidence of teratogenicity. There are no controlled data in human pregnancy; however, neonates exposed to droperidol during the third trimester are at risk of extrapyramidal neurological disturbances and/or withdrawal symptoms following delivery. During postmarketing surveillance, agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorders have been reported in these neonates. The severity of these reactions varied from self-limited to those requiring treatment or monitoring.

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.

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.
