question: I m 33 weeks pregnant and have been forced to change my medication (due to inability in the country) from 100mgs imipramine to 25mgs nortriptyline. (I am diagnosed with bipolar and am also taking 7mgs Seroquel). What are the expected effects on my baby? 2) could his change from imipramine to nortriptyline have something to do with my recently elevated blood pressure - now 142/89? thanks sandy
