Levothyroxine, a drug used to treat hypothyroidism, can lead to reduced bone mass and density in older adults with normal thyroid levels, a small cohort study has shown.
Certain other substances can cause adverse effects that may be severe. Combination of levothyroxine with ketamine may cause hypertension and tachycardia; [34] and tricyclic and tetracyclic antidepressants increase its toxicity. Soy, walnuts, fiber, calcium supplements, and iron supplements can also adversely affect absorption. [31]
Numerous symptoms and signs are associated with hypothyroidism and can be related to the underlying cause, or a direct effect of not having enough thyroid hormones. [ 15 ] [ 16 ] Hashimoto's thyroiditis may present with the mass effect of a goiter (enlarged thyroid gland). [ 15 ]

Such visits for anxiety disorders tripled, from 1.4% during the earliest time period studied, to 4.2% during the last time period. This finding echoes multiple other studies showing dramatic ...
For patients taking levothyroxine, TSH may be boosted by discontinuing levothyroxine for 3–6 weeks. [6] This long period of hormone withdrawal is required because of levothyroxine's relatively long biological half-life, and may result in symptoms of hypothyroidism in the patient. The shorter half-life of liothyronine permits a withdrawal ...
