Pregnancy is always a special situation where every action or side effect of the drug varies when compared to a situation of a non-pregnant patient. It is not only because the pregnant woman's metabolism differs due to the hormonal and other changes happened to her, but also because every medicine or its metabolite passes to the baby and shows its action there. The only thing is, be cautious, attentive and well supervised when you take any single drug in pregnancy. The interactions can vary in pregnancy, and the dosage may differ as well. Strict supervision of the Physician is mandatory.
