USE. SYNTHROID Â® (levothyroxine sodium tablets, USP) is a prescription, man-made thyroid hormone that is used to treat a condition called hypothyroidism, except in cases of temporary hypothyroidism, which is usually associated with an inflammation of the thyroid gland (thyroiditis).
There is consensus that levothyroxine should be taken in the morning on an empty stomach. A pilot study showed that levothyroxine intake at bedtime significantly decreased thyrotropin levels and increased free thyroxine and total triiodothyronine levels.To date, no large randomized trial investigating the best time of levothyroxine intake, including quality-of-life evaluation, has been performed.herefore, bedtime levothyroxine intake resulted in a direct treatment effect, with an increase in FT 4 level of 0.07 ng/dL (95% CI, 0.02-0.13; P = .01) relative to morning levothyroxine intake. Changes in TT3 levels were similar to changes in FT4 levels.
