Thyroid Tablet
FDA Label NDC 79739-7370

Thyroid Tablets, USP* for oral use is a natural preparation derived from porcine thyroid glands and
may have a strong, characteristic odor. (T3 liothyronine is approximately four times as potent as T4
levothyroxine on a microgram for microgram basis.) They provide 38 mcg levothyroxine (T4) and 9
mcg liothyronine (T3) per grain of thyroid. The inactive ingredients are microcrystalline cellulose,
lactose, silicon dioxide, and magnesium stearate.

The steps in the synthesis of the thyroid hormones are controlled by thyrotropin (Thyroid Stimulating

Hormone, TSH) secreted by the anterior pituitary. This hormone’s secretion is in turn controlled by a

feedback mechanism effected by the thyroid hormones themselves and by thyrotropin releasing

hormone (TRH), a tripeptide of hypothalamic origin. Endogenous thyroid hormone secretion is

suppressed when exogenous thyroid hormones are administered to euthyroid individuals in excess of

the normal gland’s secretion.

The mechanisms by which thyroid hormones exert their physiologic action are not well understood.

These hormones enhance oxygen consumption by most tissues of the body, increase the basal

metabolic rate, and the metabolism of carbohydrates, lipids, and proteins. Thus, they exert a profound

influence on every organ system in the body and are of particular importance in the development of

the central nervous system.

The normal thyroid gland contains approximately 200 mcg of levothyroxine (T4) per gram of gland,

and 15 mcg of liothyronine (T3) per gram. The ratio of these two hormones in the circulation does not

represent the ratio in the thyroid gland, since about 80% of peripheral liothyronine (T3) comes from

monodeiodination of levothyroxine (T4). Peripheral monodeiodination of levothyroxine (T4) at the 5

position (inner ring) also results in the formation of reverse liothyronine (T3), which is calorigenically

inactive.

Liothyronine (T3) levels are low in the fetus and newborn, in old age, in chronic caloric deprivation,

hepatic cirrhosis, renal failure, surgical stress, and chronic illnesses representing what has been

called the “T3 thyronine syndrome.”

Animal studies have shown that levothyroxine (T4) is only partially absorbed from the gastrointestinal

tract. The degree of absorption is dependent on the vehicle used for its administration and by the

character of the intestinal contents, the intestinal flora, including plasma protein, and soluble dietary

factors, all of which bind thyroid and thereby make it unavailable for diffusion. Only 41% is absorbed

when given in a gelatin capsule as opposed to a 74% absorption when given with an albumin carrier.

Depending on other factors, absorption has varied from 48 to 79% of the administered dose. Fasting

increases absorption. Malabsorption syndromes, as well as dietary factors, (children’s soybean

formula, concomitant use of anionic exchange resins such as cholestyramine) cause excessive fecal

loss. Liothyronine (T3) is almost totally absorbed, 95 % in 4 hours. The hormones contained in the

natural preparations are absorbed in a manner similar to the synthetic hormones.

More than 99% of circulating hormones are bound to serum proteins, including thyroid-binding

globulin (TBg), thyroid-binding prealbumin (TBPA), and albumin (TBa), whose capacities and affinities

vary for the hormones. The higher affinity of levothyroxine (T4) for both TBg and TBPA as compared to

liothyronine (T3) partially explains the higher serum levels and longer half-life of the former hormone.

Both protein-bound hormones exist in reverse equilibrium with minute amounts of free hormone, the

latter accounting for the metabolic activity.

Deiodination of levothyroxine (T4) occurs at a number of sites, including liver, kidney, and other

tissues. The conjugated hormone, in the form of glucuronide or sulfate, is found in the bile and gut

where it may complete an enterohepatic circulation. 85% of levothyroxine (T4) metabolized daily is

deiodinated.

Thyroid Tablets, USP are indicated:

1. As replacement or supplemental therapy in patients with hypothyroidism of any etiology, except

transient hypothyroidism during the recovery phase of subacute thyroiditis. This category includes

cretinism, myxedema, and ordinary hypothyroidism in patients of any age (children, adults, the

elderly), or state (including pregnancy); primary hypothyroidism resulting from functional deficiency,

primary atrophy, partial or total absence of thyroid gland, or the effects of surgery, radiation, or drugs,

with or without the presence of goiter; and secondary (pituitary), or tertiary (hypothalamic)

hypothyroidism (See WARNINGS).

2. As pituitary TSH suppressants, in the treatment or prevention of various types of euthyroid goiters,

including thyroid nodules, subacute or chronic lymphocytic thyroiditis (Hashimoto’s), multinodular

goiter, and in the management of thyroid cancer.

Thyroid hormone preparations are generally contraindicated in patients with diagnosed but as yet

uncorrected adrenal cortical insufficiency, untreated thyrotoxicosis, and apparent hypersensitivity to

any of their active or extraneous constituents. There is no well-documented evidence from the

literature, however, of true allergic or idiosyncratic reactions to thyroid hormone.

The use of thyroid hormones in the therapy of obesity, alone or combined with other drugs, is

unjustified and has been shown to be ineffective. Neither is their use justified for the treatment of

male or female infertility unless this condition is accompanied by hypothyroidism.

The active ingredient (desiccated natural thyroid) in Thyroid Tablets, USP is derived from porcine (pig)

thyroid glands of pigs processed for human food consumption. Vitruvias is not aware of any cases of

disease transmission associated with the use of Thyroid Tablets, USP.

Thyroid hormones should be used with great caution in a number of circumstances where the

integrity of the cardiovascular system, particularly the coronary arteries, is suspected. These include

patients with angina pectoris or the elderly, in whom there is a greater likelihood of occult cardiac

disease. In these patients therapy should be initiated with low doses, i.e., 15-30 mg Thyroid Tablets,

USP. When, in such patients, a euthyroid state can only be reached at the expense of an aggravation

of the cardiovascular disease, thyroid hormone dosage should be reduced.

Thyroid hormone therapy in patients with concomitant diabetes mellitus or diabetes insipidus or

adrenal cortical insufficiency aggravates the intensity of their symptoms. Appropriate adjustments of

the various therapeutic measures directed at these concomitant endocrine diseases are required. The

therapy of myxedema coma requires simultaneous administration of glucocorticoids (See DOSAGE AND ADMINISTRATION).

Hypothyroidism decreases and hyperthyroidism increases the sensitivity to oral anticoagulants.

Prothrombin time should be closely monitored in thyroid-treated patients on oral anticoagulants and

dosage of the latter agents adjusted on the basis of frequent prothrombin time determinations. In

infants, excessive doses of thyroid hormone preparations may produce craniosynostosis.

Patients on thyroid hormone preparations and parents of children on thyroid therapy should be

informed that:

1. Replacement therapy is to be taken essentially for life, with the exception of cases of transient

hypothyroidism, usually associated with thyroiditis, and in those patients receiving a therapeutic trial

of the drug.

2. They should immediately report during the course of therapy any signs or symptoms of thyroid

hormone toxicity, e.g., chest pain, increased pulse rate, palpitations, excessive sweating, heat

intolerance, nervousness, or any other unusual event.

3. In case of concomitant diabetes mellitus, the daily dosage of antidiabetic medication may need readjustment as thyroid hormone replacement is achieved. If thyroid medication is stopped, a

downward readjustment of the dosage of insulin or oral hypoglycemic agent may be necessary to

avoid hypoglycemia. At all times, close monitoring of urinary glucose levels is mandatory in such

patients.

4. In case of concomitant oral anticoagulant therapy, the prothrombin time should be measured

frequently to determine if the dosage of oral anticoagulants is to be readjusted.

5. Partial loss of hair may be experienced by children in the first few months of thyroid therapy, but

this is usually a transient phenomenon and later recovery is usually the rule.

Treatment of patients with thyroid hormones requires the periodic assessment of thyroid status by

means of appropriate laboratory tests besides the full clinical evaluation. The TSH suppression test

can be used to test the effectiveness of any thyroid preparation bearing in mind the relative

insensitivity of the infant pituitary to the negative feedback effect of thyroid hormones. Serum T4

levels can be used to test the effectiveness of all thyroid medications except T3. When the total serum

T4 is low but TSH is normal, a test specific to assess unbound (free) T4 levels is warranted. Specific

measurements of T4 and T3 by competitive protein binding or radioimmunoassay are not influenced

by blood levels of organic or inorganic iodine.

Oral Anticoagulants—Thyroid hormones appear to increase catabolism of vitamin K-dependent

clotting factors. If oral anticoagulants are also being given, compensatory increases in clotting factor

synthesis are impaired. Patients stabilized on oral anticoagulants who are found to require thyroid

replacement therapy should be watched very closely when thyroid is started. If a patient is truly

hypothyroid, it is likely that a reduction in anticoagulant dosage will be required. No special

precautions appear to be necessary when oral anticoagulant therapy is begun in a patient already

stabilized on maintenance thyroid replacement therapy.

Insulin or Oral Hypoglycemics—Initiating thyroid replacement therapy may cause increases in insulin

or oral hypoglycemic requirements. The effects seen are poorly understood and depend upon a variety

of factors such as dose and type of thyroid preparations and endocrine status of the patient. Patients

receiving insulin or oral hypoglycemics should be closely watched during initiation of thyroid

replacement therapy.

Cholestyramine or Colestipol—Cholestyramine or colestipol binds both levothyroxine (T4) and

liothyronine (T3) in the intestine, thus impairing absorption of these thyroid hormones. In vitro studies

indicate that the binding is not easily removed. Therefore four to five hours should elapse between

administration of cholestyramine or colestipol and thyroid hormones.

Estrogen, Oral Contraceptives—Estrogens tend to increase serum thyroxine-binding globulin (TBg). In

a patient with a nonfunctioning thyroid gland who is receiving thyroid replacement therapy, free

levothyroxine (T4) may be decreased when estrogens are started thus increasing thyroid

requirements. However, if the patient’s thyroid gland has sufficient function, the decreased free

levothyroxine (T4) will result in a compensatory increase in levothyroxine (T4) output by the thyroid.

Therefore, patients without a functioning thyroid gland who are on thyroid replacement therapy may

need to increase their thyroid dose if estrogens or estrogen-containing oral contraceptives are given.

The following drugs or moieties are known to interfere with laboratory tests performed in patients on

thyroid hormone therapy: androgens, corticosteroids, estrogens, oral contraceptives containing

estrogens, iodine-containing preparations, and the numerous preparations containing salicylates.

1. Changes in TBg concentration should be taken into consideration in the interpretation of

levothyroxine (T4) and liothyronine (T3) values. In such cases, the unbound (free) hormone should be

measured. Pregnancy, estrogens, and estrogen-containing oral contraceptives increase TBg

concentrations. TBg may also be increased during infectious hepatitis. Decreases in TBg

concentrations are observed in nephrosis, acromegaly, and after androgen or corticosteroid therapy.

Familial hyper- or hypothyroxine-binding-globulinemias have been described. The incidence of TBg

deficiency approximates 1 in 9000. The binding of levothyroxine by TBPA is inhibited by salicylates.

2. Medicinal or dietary iodine interferes with all in vivo tests of radio-iodine uptake, producing low

uptakes which may not be relative of a true decrease in hormone synthesis.

3. The persistence of clinical and laboratory evidence of hypothyroidism in spite of adequate dosage

replacement indicates either poor patient compliance, poor absorption, excessive fecal loss, or

inactivity of the preparation. Intracellular resistance to thyroid hormone is quite rare.

A reportedly apparent association between prolonged thyroid therapy and breast cancer has not been

confirmed and patients on thyroid for established indications should not discontinue therapy. No

confirmatory long-term studies in animals have been performed to evaluate carcinogenic potential,

mutagenicity, or impairment of fertility in either males or females.

Thyroid hormones do not readily cross the placental barrier. The clinical experience to date does not

indicate any adverse effect on fetuses when thyroid hormones are administered to pregnant women.

On the basis of current knowledge, thyroid replacement therapy to hypothyroid women should not be

discontinued during pregnancy.

Minimal amounts of thyroid hormones are excreted in human milk. Thyroid is not associated with

serious adverse reactions and does not have a known tumorigenic potential. However, caution should

be exercised when thyroid is administered to a nursing woman.

Pregnant mothers provide little or no thyroid hormone to the fetus. The incidence of congenital

hypothyroidism is relatively high (1:4,000) and the hypothyroid fetus would not derive any benefit from

the small amounts of hormone crossing the placental barrier. Routine determinations of serum T4

and/or TSH is strongly advised in neonates in view of the deleterious effects of thyroid deficiency on

growth and development.

Treatment should be initiated immediately upon diagnosis, and maintained for life, unless transient

hypothyroidism is suspected; in which case, therapy may be interrupted for 2 to 8 weeks after the age

of 3 years to reassess the condition. Cessation of therapy is justified in patients who have maintained

a normal TSH during those 2 to 8 weeks.

Adverse reactions other than those indicative of hyperthyroidism because of therapeutic overdosage,

either initially or during the maintenance period, are rare (See OVERDOSAGE).

Signs and Symptoms

Excessive doses of thyroid result in a hypermetabolic state resembling in every respect the condition

of endogenous origin. The condition may be self-induced.

Treatment of Overdosage

Dosage should be reduced or therapy temporarily discontinued if signs and symptoms of overdosage

appear.

Treatment may be reinstituted at a lower dosage. In normal individuals, normal

hypothalamic-pituitary-thyroid axis function is restored in 6 to 8 weeks after thyroid suppression.

Treatment of acute massive thyroid hormone overdosage is aimed at reducing gastrointestinal

absorption of the drugs and counteracting central and peripheral effects, mainly those of increased

sympathetic activity. Vomiting may be induced initially if further gastrointestinal absorption can

reasonably be prevented and barring contraindications such as coma, convulsions, or loss of the

gagging reflex. Treatment is symptomatic and supportive. Oxygen may be administered and ventilation

maintained. Cardiac glycosides may be indicated if congestive heart failure develops. Measures to

control fever, hypoglycemia, or fluid loss should be instituted if needed. Antiadrenergic agents,

particularly propranolol, have been used advantageously in the treatment of increased sympathetic

activity. Propranolol may be administered intravenously at a dosage of 1 to 3 mg, over a 10-minute

period or orally, 80 to 160 mg/day, initially, especially when no contraindications exist for its use.

Other adjunctive measures may include administration of cholestyramine to interfere with thyroxine

absorption, and glucocorticoids to inhibit conversion of T4 to T3.

The dosage of thyroid hormones is determined by the indication and must in every case be

individualized according to patient response and laboratory findings.

Thyroid hormones are given orally. In acute, emergency conditions, injectable levothyroxine sodium

(T4) may be given intravenously when oral administration is not feasible or desirable, as in the

treatment of myxedema coma, or during total parenteral nutrition. Intramuscular administration is not

advisable because of reported poor absorption.

Hypothyroidism

Therapy is usually instituted using low doses, with increments which depend on the cardiovascular

status of the patient. The usual starting dose is 30 mg Thyroid Tablets, USP, with increments of 15 mg

every 2 to 3 weeks. A lower starting dosage, 15 mg/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/day. Failure to respond to doses of 180 mg suggests lack

of compliance or malabsorption. Maintenance dosages 60 to 120 mg/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.

Liothyronine (T3) may be used in preference to levothyroxine (T4) during radio-isotope scanning

procedures, since induction of hypothyroidism in those cases is more abrupt and can be of shorter

duration. It may also be preferred when impairment of peripheral conversion of levothyroxine (T4) and

liothyronine (T3) is suspected.

Myxedema Coma

Myxedema coma is usually precipitated in the hypothyroid patient of long-standing by intercurrent

illness or drugs such as sedatives and anesthetics and should be considered a medical emergency.

Therapy should be directed at the correction of electrolyte disturbances and possible infection besides

the administration of thyroid hormones. Corticosteroids should be administered routinely.

Levothyroxine (T4) and liothyronine (T3) may be administered via a nasogastric tube but the preferred

route of administration of both hormones is intravenous. Levothyroxine sodium (T4) is given at a

starting dose of 400 mcg (100 mcg/mL) given rapidly, and is usually well tolerated, even in the elderly.

This initial dose is followed by daily supplements of 100 to 200 mcg given IV. Normal T4 levels are

achieved in 24 hours followed in 3 days by threefold elevation of T3. Oral therapy with thyroid

hormone would be resumed as soon as the clinical situation has been stabilized and the patient is

able to take oral medication.

Thyroid Cancer

Exogenous thyroid hormone may produce regression of metastases from follicular and papillary

carcinoma of the thyroid and is used as ancillary therapy of these conditions with radioactive iodine.

TSH should be suppressed to low or undetectable levels. Therefore, larger amounts of thyroid

hormone than those used for replacement therapy are required. Medullary carcinoma of the thyroid is

usually unresponsive to this therapy.

Thyroid Suppression Therapy

Administration of thyroid hormone in doses higher than those produced physiologically by the gland

results in suppression of the production of endogenous hormone. This is the basis for the thyroid

suppression test and is used as an aid in the diagnosis of patients with signs of mild hyperthyroidism

in whom base line laboratory tests appear normal, or to demonstrate thyroid gland autonomy in

patients with Grave’s ophthalmopathy. 131I uptake is determined before and after the administration

of the exogenous hormone. A 50% or greater suppression of uptake indicates a normal

thyroid-pituitary axis and thus rules out thyroid gland autonomy.

For adults, the usual suppressive dose of levothyroxine (T4) is 1.56 mcg/kg of body weight per day

given for 7 to 10 days. These doses usually yield normal serum T4 and T3 levels and lack of response

to TSH.

Thyroid hormones should be administered cautiously to patients in whom there is strong suspicion of

thyroid gland autonomy, in view of the fact that the exogenous hormone effects will be additive to the

endogenous source.

Pediatric Dosage

Pediatric dosage should follow the recommendations summarized in Table 1. In infants with

congenital hypothyroidism, therapy with full doses should be instituted as soon as the diagnosis has

been made.
