Went for my physical today and my Dr. was going over my blood tests....she said my thryoid (TSH) level was a little high and that might be the reason why I am still having pvc's while taking toporol....I was taking levoxyl for my thyroid daily, now they want me to take it only 5 days a week, take it for 3 days, skip a day, take it for two days and then skip a day. I'm hopeful that when my thyroid normalizes I won't experience so many pvcs. All of you who have pvc's GET YOUR THYROID CHECKED! Take care and MERRY CHRISTMAS!!!
