Is prochlorperazine-rectal safe to take if I'm pregnant or breastfeeding?
Prochlorperazine has not been adequately evaluated in pregnant women. Due to the lack of conclusive safety data, prochlorperazine should be avoided in pregnancy except in cases of severe nausea and vomiting that requires treatment and potential benefit justifies the potential risk to the fetus.
It is not known if prochlorperazine is excreted into human milk. Other phenothiazines are excreted into breast milk. If clearly needed, prochlorperazine should be used cautiously in females who are nursing.
