This just show how on the ball you have to be. Last month my prescription was wildly wrong, instead of 75mcg per day for two months I received 150mcg per day for two months!! I simply cut them in half, the excess I gave my daughter as up to now, although being really well on levo she's not been prescribed it, that could now change as she's presented herself as living proof to her GP! Today I received another prescription, guess what, I'm looking at 300mcg levothyroxine!!! This beggars belief! Especially as the prescription slip says 100mcg one each morning etc but even that is out of date!!! Isn't all the info supposed to be on computer and fool proof?? They spend enough time looking at the darned screen instead of listening and looking at the patient!!!! Unbelievable!!!
