Goodmorning!!
I use to be on imuran, but am now on cellcept, as it works better for me. Everyone is different regarding how each drug works for them!
#1 Yes you still take mestinon, I tell my family this is my "muscle tablet", it helps my muscles work(an easy way of telling them what its for) Mestinon gives you a boost, I still take 2 a day, one in the morning and one at lunchtime.
#2 hmmm side effects, from what I can remember I lost a bit more hair than usual, and maybe made me a bit sick, but its hard to tell whether that was from the other drugs as well.
#3 Not sure about testing for it in the blood
#4 My neuro decided to change me from imuran to cellcept because he didn't think it was working as well as it could, but I do know people who are doing well on it!
hope this helps a little, have a good weekend
Kate
