Eltroxin general information
What is Eltroxin used for?
Eltroxin tablets are used to treat hypothyroidism or underactive thyroid, a condition in which the thyroid gland does not make enough thyroid hormone (thyroxine) needed to regulate your body’s growth and metabolism. Hypothyroidism can be idiopathic (of unknown cause) or congenital as in the case of the autoimmune disease Hashimoto’s thyroiditis, where the thyroid gland is destroyed by the immune system; it can also be the result of thyroid surgery. Eltroxin tablets are also used to treat thyroid goitre, which is an enlarged thyroid gland caused by extreme growth of thyroid tissue to compensate for lack of thyroid hormone; also to treat thyroid cancer. Eltroxin tablets are a replacement hormone to relieve the symptoms of hypothyroidism, including, tiredness, muscle weakness, cramps, feeling the cold, a slow heart rate, dry and flaky skin, hair loss, a deep husky voice and weight gain.
How does Eltroxin work?
Eltroxin tablets contain levothyroxine sodium, a synthetic thyroid hormone that is identical to the naturally occurring thyroid hormone thyroxine or T4, produced by the thyroid gland. Levothyroxine is converted to the more active form of thyroid hormone (T3), which interacts with a specific receptor inside cells to stimulate proteins needed to manage and regulate a variety of processes including how the body regulates temperature, metabolises nutrients and controls growth and development. Thyroxine regulates the production of another hormone called thyroid stimulating hormone (TSH) which in turn controls how much thyroxine is produced. Eltroxin tablets regulate TSH production in the same way and therefore substitutes for a lack of endogenous thyroxine produced by the thyroid gland.
What does Eltroxin contain?
Eltroxin tablets contain the active ingredient levothyroxine, which replaces the lack of endogenous thyroxine (produced by the thyroid gland) to regulate normal growth and metabolism. They also contain acacia, confectioner’s sugar, lactose, magnesium stearate, povidone, talc and colour additives (D&C Yellow No. 10 and FD&C Yellow No. 6).

Treating underactive thyroid (hypothyroidism) with Eltroxin

Eltroxin tablets are used to treat the symptoms of hypothyroidism, including, tiredness, muscle weakness, cramps, feeling the cold, a slow heart rate, dry and flaky skin, hair loss, a deep husky voice and weight gain.
