When I was on PTU, due to a misunderstanding with my doctor, I took too much for about six weeks…or at least more than he wanted me to take. I was on beta blockers for heart symptoms, specifically was having chest pain. Saw doc about something else and he asked in passing how I was doing with the PTU. I was still having chest pains, so he told me to up my meds to four times/day instead of three. I increased both PTU *and* beta blockers. He noticed immediately when I had my next blood test and dropped me back to three times/day on the PTU. No harm done as far as I could tell except lowering my levels to low normal from mid-normal…maybe a little more tired than usual was all. Hope this helps.
I Glynis! I was on PTU for about 1 1/2 yrs. Most of that time I was taking 600 mgs a day, which is a total of 12 of those nasty little buggers, taken 3 x a day. I tried everything to try to remember whether I took them or not. What worked for me is a small container that I put all 12 of the pills in for the day, counting off 4 at 8 hr intervals. If I had a dime for every time I went back to that container and counted whether I’d taken the medication or not!! I really think its the PTU that causes the concentration problems. As for your question about accidentally not taking them or taking too much. Hey, we GD people are only human. There are times when I didn’t take all 12 pills, especially if your sick with a virus. I can’t say I ever took more medication than needed. Any way I hope I was some help. colleen
