dawnydawn1 No. You leave off Levo for 24 hours and fast overnight (you can have water). Take your levo after the blood draw.
Do NOT take any thyroxine within 12 hours of a blood test.
No. Leave 24 hours or so from last dose, and fast from the night before- only water. Take levo after blood test. This helps to stop GP or endo from reducing levo dose unneccessarily
