This is a little late, but I too had problems on Labetelol and it didn't seem to control my BP that well when I had severe kidney disease. I was switched to Metoprolol after 2 months along with Norvasc (if I remember correctly) and it made a huge difference. I think it ended up helping me get off dialysis much faster. I'm now still on Metoprolol, but a very low dose, and am currently 34 weeks pregnant. My BP numbers have been excellent through the whole pregnancy, though I did increase my dose a bit for about 1-2 months then decreased it back to the usual dose for the rest of the pregnancy.
Hope that helps. Sarah
