Hi there, my GP has started me on Levothyroxine 25mcg a day first thing in the morning.
I took my first dose yesterday and the muscles in my hand/thumb begun to twitch. I can't exactly say that it hurt but it was just more the fact it bothered me.
Also I took today's dose at the same time, again on an empty stomach and I had very bad stomach cramps later on tonight. I put it down to a painful period as it hasn't yet started and is due, but then I had an urgency to go to the loo within 5 minutes after the cramps and I had very bad diarrhoea! Is this a side effect or am I given too much T4? One thing I did notice before all of this was that I did begin to get very thirsty and drank like a fish, so can the T4 dehydrate you? Should I be increasing my water intake and will my body adjust to the T4 if that's what's causing this?
I didn't think I could develop side effects to the T4 so soon, so if anyone has any ideas please let me know as I can maybe raise this problem with the doctor.
