ERFA Thyroid general information
What is ERFA Thyroid used for?
ERFA Thyroid tablets 125mg are used to treat hypothyroidism or underactive thyroid, a condition in which the thyroid gland does not make enough thyroid hormone needed to regulate the body’s growth and metabolism. ERFA Thyroid tablets 125mg are a natural replacement hormone, derived from desiccated pig thyroid gland, containing both forms of thyroid hormone or thyroxine (T3 and T4), which help 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. ERFA Thyroid tablets 125mg can also be used to help treat hypothyroidism caused by surgical removal of, or damage to the thyroid gland, as well as treating thyroid goitre (enlarged thyroid gland) and thyroid cancer.
How does ERFA Thyroid work?
ERFA Thyroid tablets 125mg consist of an extract produced from pig thyroid glands which contains both forms of thyroid hormone; thyroxine (levothyroxine or T4), which is the stable but inactive form, and liothyronine (L-triiodothyronine or T3), the unstable active form. Both forms of thyroid hormone are carried in the circulation bound to protein. Thyroxine (T4) is converted to the more active form of thyroid hormone (T3) in the liver, kidney and other tissues of the body and T3 interacts with a specific receptor inside cells to stimulate proteins needed to manage and control a variety of processes, including how the body regulates temperature, metabolises nutrients and controls growth and development. Thyroid hormones regulate the production by the pituitary gland of another hormone called thyroid stimulating hormone (TSH), which in turn controls how much thyroid hormone is produced. ERFA Thyroid tablets 125mg regulate TSH production in the same way and this is how it works when used for treating thyroid goitre or thyroid cancer by suppressing TSH production.
What does ERFA Thyroid contain?
ERFA Thyroid tablets 125mg contain desiccated (dried) extract of pig thyroid gland, in which the active ingredient is thyroid hormone and contains both forms of thyroid hormone in the proportions found naturally in the thyroid gland, which is in the ratio 4:1 of T4 to T3. Also contains lactose, cornstarch, magnesium stearate, sugar and talc. Erfa Thyroid is gluten, paraben, sulfite and tartrazine free.

ERFA Thyroid tablets 125mg 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.
What is the difference between natural and synthetic thyroid hormones?
ERFA Thyroid tablets 125mg contain an extract produced from pig thyroid glands which contains both forms of thyroid hormone; thyroxine (levothyroxine or T4) and liothyronine (L-triiodothyronine or T3).

Both natural and synthetic hormones work in the same way to treat thyroid disease.
