Methotrimeprazine Pregnancy Warnings

This drug is only recommended for use in women of childbearing potential or during pregnancy when there are no alternatives and the benefit outweighs the risk.

AU TGA pregnancy category: Not formally assigned to a pregnancy category.

Comments:
-Some authorities state that safety has not been established in pregnancy, and use is not recommended in pregnancy or in women of childbearing potential not using contraception.
-Use of adequate methods of contraception should be encouraged.
-Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery.
-Exposed neonates should be monitored and treated for the signs/symptoms of extrapyramidal syndrome and/or withdrawal symptoms.

Animal studies using other phenothiazines have revealed contradictory evidence of fetal harm when given during the first trimester. Animal studies using this drug have not been reported. There are no controlled data in human pregnancy.

There have been reports of agitation, bradycardia, feeding disorder, hyper/hypotonia, respiratory distress, somnolence, tachypnea, and tremor in neonates exposed to antipsychotic drugs during the third trimester of pregnancy. Complications occurred more frequently when patients were given antimuscarinic or psychotropic drugs concomitantly; however, the events have occurred with antipsychotic use alone. Phenothiazine-specific neonatal adverse events (e.g., abdominal bloating, delayed meconium passage, feeding disorder, meconium ileus, tachycardia) have been reported. These complications have varied in severity; while in some cases symptoms have been self-limited, in other cases neonates have required intensive care unit support and prolonged hospitalization.

Hyperprolactinemia may be associated with impaired fertility in men and women. There are no controlled data in human females or males.
