ERFA Thyroid is a natural replacement for thyroid hormone to counteract age-related thyroid problems. Thyroid decline affects every cell in our body, resulting in a wide range of age-related problems. The thyroid gland is an endocrine gland located just under the Adam's apple in the throat. It secretes a hormone into the bloodstream called thyroxine, which controls the body's metabolism, the rate at which the body burns calories for energy. It also controls the body's utilization of fat. A decline in the secretion of hormones from the thyroid gland (hypothyroidism) can result in poor concentration, confusion, memory problems, cold hands and feet, weight gain, menstrual problems, sleep disorders, dry skin, thinning hair and low energy levels. An underactive thyroid is also a major cause of a common painful musculoskeletal condition known as fibromyalgia.

Dosage Guidelines

Hypothyroidism: Therapy is usually instituted using low doses the increments that depend on the cardiovascular status of the patient. The usual starting dose is 30 mg with increments of 15 mg every 2 to 3 weeks. A lower starting dosage, 15 mg per day is recommended in patients with long standing myxedema, particularly if cardiovascular impairment is suspected, in which case extreme caution is recommended. The appearance of angina is an indication for a reduction in dosage. Most patients require 60 to 120 mg per day. Failure to respond to doses of 180 mg suggests lack of compliance or malabsorption. Maintenance dosages 60 to 120 mg per day usually result in normal serum T4 and T3 levels. Adequate therapy usually results in normal TSH and T4 levels after 2 to 3 weeks of therapy. Readjustment of thyroid hormone dosage should be made within the first four weeks of therapy, after proper clinical and laboratory evaluations, including serum levels of T4, bound and free and TSH.

How to Use

Take this medication by mouth, usually once daily before breakfast or as directed by your doctor. The dosage of thyroid hormones is determined by the indication and must in every case be individualized according to patient response and laboratory findings. One grain (equivalent to 60 mg) or higher dosages are potent and usually require temperature monitoring and occasional blood tests. Persons with more serious thyroid conditions are often prescribed one grain. Dosages under a physician's guidance can often reach three to five grains daily. Dosages of more than one grain are usually increased by a grain over one to two weeks. Quarter grain and half grain whole thyroid supplements (15 mg to 30 mg) provide less potency and are used to support an aging thyroid condition. However, long-term use of low dose whole thyroid extracts may also require occasional breaks and monitoring.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up unless your doctor instructs you to do so. Call your doctor if you miss 2 or more doses in a row. Ask your doctor ahead of time what to do about a missed dose and follow your doctor's specific directions.
