Hi, My doctor has advised me to take 100 mcg Levothyroxine . So I took two tablets of 50 mcg each day before the breakfast. (In fact, I use 2 x 50 mcg tablets per day, instead of buying new 100 mcg tablets) I see in Merck s drug manual that 2 x 50 mcg is smilar to 100 mcg. But, since I am not sure, I just want to ask that Does two 50 mcg pills have the same effect as one 100 mcg pill? Does it make any problem to take two tablets every day?
