Stemetil and possible effects on baby

NVP Counselor
Date: 2004-04-07

Question:
What are the risks of stemetil during the 13-14wk? I have found info. of possible adverse effects such as lethargy or paradoxical hperexcitability, tremor and low apgar score. My question is are these risks only if the drugs are taken close to delivery or maybe becasue of prolonged use? and if these possible adverse effects really happen, are they a permanent or a temporary situation?

Answer:
Stemetil (prochlorperazine) is part of the phenothiazine group of medications. They are known not to be teratogenic (do not cause birth defects). For more detailed information about Stemetil's possible effects on the baby, based on duration of intake or timing of use during pregnancy, please speak to your doctor, pharmacist or a teratogen counselor. Motherisk counselors are available Monday through Friday, 9 a.m. to 5 p.m. EST by calling (416) 813-6780. Or visit OTIS to find a teratogen information service in your area.
