Taking levothyroxine at night may improve TSH, Free T4 and T3 levels. consequences for the millions of patients who take l-thyroxine daily.
Twenty-four-hour average serum values amounted to (mean /- SD, morning vs bedtime ingestion TSH, 5.1 /- 0.9 vs 1.2 /- 0.3 mU/l (P 0.01 FT4, 16.7 /- 1.0 vs 19.3 /- 0.7 pmol/l (P 0.01 T3, 1.5 /- 0.05 vs 1.6 /- 0.1 nmol/l (P 0.01).May 12, 2011.

Following this first hospital admission, all women were asked to switch the administration time from morning to bedtime or vice versa. After 2 months they were readmitted for a 24-h period of hourly blood sampling.Primary outcome measures were thyroid hormone levels; secondary outcome measures were creatinine and lipid levels, body mass index, heart rate, and quality of life. Results Ninety patients completed the trial and were available for analysis.
Secondary outcomes, including quality-of-life questionnaires (36-Item Short Form Health Survey, Hospital Anxiety and Depression Scale, 20-Item Multidimensional Fatigue Inventory, and a symptoms questionnaire showed no significant changes between morning vs bedtime intake of levothyroxine.OBJECTIVE : Standard drug information resources recommend that l-thyroxine be taken half an hour before breakfast on an empty stomach, to prevent interference of its intestinal uptake by food or medication.
