I was on venlafaxine when i conceived my 5th, continued to take it (a high dose of 225mg) throughout my pregnancy too.
Baby was born to term via elective c-section, weighing 6lbs 1 3/4 oz....a whole TWO pounds lighter than my other 4!!!
he was a tad 'jittery' and had a low blood sugar, and spent 36 hours in the SCBU. He was a little slow to start feeding and get to grips with it (but that could have been cos my boob was twice the size of his head with massive nips!!)
and i also found that he had no tears when he cried...not even when he really sobbed the place down, until he stopped breast feeding, then his tears came in (he was about maybe.....22 months old) I put this down to the venlafaxine, as one of the symptoms it lists for people who take it is dry eyes.....but this is only my assumption
other than that all was fine....he is 4 now, very clever, great with numbers and phonics...a little smaller than some of the other kids, but there are smaller than him. he his all his milestones, and did them well, and is a normal wonderful 4 year old.
i found i was better able to cope with him too (i suffer from PND) because i hadnt had a break from my anti-d's and didnt have to wait for them to build up again.
hope that helps xxx
