What about taking phenothiazine antipsychotics during pregnancy or while breastfeeding?
Safe and effective use of phenothiazine antipsychotics during pregnancy has not been established. Newborns exposed to phenothiazine antipsychotics are at risk for extrapyramidal and withdrawal symptoms following delivery. Phenothiazine antipsychotics should only be used if clearly needed when benefits outweigh potential risks to the fetus.
Phenothiazine antipsychotics may enter breast milk; therefore, they should be used with caution in women who are breastfeeding. To avoid potential risks to the newborn, a decision should be made whether to discontinue the drug or to discontinue nursing.
