pregnancy): shaking, muscle stiffness and/or weakness, sleepiness, agitation, breathing problems and difficulty in feeding. If your baby develops any of
these symptoms you may need to contact your doctor.

planning to breast-feed talk to your doctor before taking this medicine.
Chlorpromazine may make it more difficult for a woman to get pregnant due to it reducing her fertility.
