For those who noted that the man-made drug Synthroid was in the number one spot on the graph, Statista reports that, “In 2022, prescription drug synthroid – used for the treatment of hypothyroidism – was the most dispensed drug in Canada, coming to a total of more than 20.5 million prescriptions.”
Upon further investigation, Synthroid is the brand name for levothyroxine. “Levothyroxine, also known as L-thyroxine, is a synthetic form of the thyroid hormone thyroxine (T4).[4][7] It is used to treat thyroid hormone deficiency (hypothyroidism), including a severe form known as myxedema coma.[4] It may also be used to treat and prevent certain types of thyroid tumors.[4] It is not indicated for weight loss.[4]“
