Evaluation of the common mistakes made by patients in the use of Levothyroxine.

Although synthetic thyroxine (T4), L-triiodothyronine (T3), and T3/T4 combinations are available for correction of hypothyroidism, the treatment of choice is T4 alone for the vast majority of patients. The bioavailability of a drug depends on many factors such as drug disintegration and dissolution, time of drug intake, storage conditions, diet, and the tablet's size. The T4 is recommended to be taken as a single dose with a glass of water, preferably on an empty stomach, at least 0.5 h to 1 h before breakfast.eninfo:eu-repo/semantics/closedAccessCommon MistakesHypothyroidismLevothyroxineOther259e107e10810.1016/j.ejim.2014.09.002N/AQ1
