I was on a beta blocker through two children. They say there is a small risk. The fetus could be smaller but for the most part not a huge risk. I took 40 mgs of nadolol twice a day the whole time and I was fine. I tried to cut it in half but I was risking having attacks which could also cause me to pass out which was pretty dangerous towards the end. Who knows where and when I would feel like passing out. Anyway.....I was fine!!!!
I'm 21 weeks pregnant,and taking atenolol 25mg for PAF and PSVT. The pregnancy will increase your blood volume, and put an additional stress on your heart, but a couple of posters here who have had it while they were pregnant, have reported that it went completely away during their pregnancy. Mine however was diagnosed during this pregnancy. The atenolol seems to be keeping it under control so far. My doctors have told me there is a slight risk of having a smaller baby, but they will monitor me closely in the 3rd trimester. I'm on a pretty small dose as well.
Hi and congrats! I have PSVT also, and my pregnancies pretty much just increased the single ectopics, not the actual PSVT. I did have a couple of episodes, but I might have had them anyhow. I converted on my own within seconds. Beta blockers can be taken during pregnancy, certain ones are safer than others (Coreg is NOT a good choice during pregnancy, Metoprolol seems to be prescribed to those who are pregnant). Best wishes to you!
