ANYBODY HERE TAKES T3?

[Guest guest]

Hello all, i am new here, i am taking armour-thyroid (60 mgs) right now for my

low-thyroid, but my doctor switched me to T3 becuase it is the biologically

active

GENERIC NAME: liothyronine sodium BRAND NAME: Cytomel, Triostat DRUG CLASS

AND MECHANISM: Liothyronine sodium is a synthetic (man-made) version of one of

the two hormones made by the thyroid gland, triiodothyronine. It is used for

treating individuals who are hypothyroid (do not produce enough thyroid

hormones). Thyroid hormones increase the metabolism (activity) of all cells in

the body. In the fetus, newborn infant and child, thyroid hormones promote

growth and development of tissues. In adults, thyroid hormones help to maintain

the function of the brain, the use of food by the body, and body temperature.

PRESCRIPTION: yes

GENERIC AVAILABLE: yes

PREPARATIONS: Tablets: 5, 25, 50 mcg. Injection: 10 mcg/ml

STORAGE:Store tablets at room temperature 20-25°C (68-77°F) and injectable

preparation between 2-8°C (36-46°F )

PRESCRIBED FOR: Liothyronine is used to treat hypothyroidism (low production

of thyroid hormone) in adults and children. Prolonged hypothyroidism can result

in a condition called myxedema in which patients develop swollen lips, thickened

nose, and unusual deposits of material in the skin that are dry and waxy. These

deposits also may appear in body tissues other than the skin. Liothyronine also

is used in a test of the thyroid gland to determine if the thyroid is

functioning normally.

DOSING: The usual starting dose of liothyronine is 5 to 25 mcg per day. The

dose then is adjusted based on the patient's response and the blood levels of

thyroid hormone. Optimal liothyronine doses are different for each patient and

vary depending on the patient's age, weight, symptoms, blood levels of thyroid

hormone and underlying conditions such as heart disease. Individuals who are

hypothyroid will require thyroid hormone for life. Generic and branded tablets

of liothyronine may differ in the amount of liothyronine that is absorbed into

the body and the distribution of the liothyronine throughout the body. This

means that ingestion of 5 mcg of generic or branded liothyronine may not have

the same effect on the body as 5 mcg of another generic or branded liothyronine.

Practically speaking, this means that when changing between liothyronine

manufactured by different pharmaceutical companies, a change in dose may be

necessary to maintain the desired effect or to

prevent toxicity.

DRUG INTERACTIONS:Thyroid hormone affects the body's handling of many drugs.

Generally, hypothyroidism (decreased concentration of thyroid hormone) reduces

the effects of the body on drugs (metabolism of drugs) while hyperthyroidism

(increased concentration of thyroid hormone) increases the effects. Therefore,

individuals who are hypothyroid will eliminate drugs more slowly and those with

hyperthyroidism will eliminate drugs faster compared with individuals with

normal levels of thyroid hormone. This principle also applies to the metabolism

of drugs that must be metabolized (changed) by the body into their active forms

in order to have an effect. Therefore, liothyronine and other thyroid hormones

may change the action of many drugs. The elimination of theophylline

(Theo-Dur) and similar drugs increases as the dose of thyroid hormone increases.

Individuals who are hypothyroid have slower theophylline elimination. Therefore,

when the concentration of thyroid hormone is

returned to normal with liothyronine, the elimination of theophylline is

increased. This reduces the concentration of theophylline in the body and can

reduce the effectiveness of theophylline. Patients who are treated for thyroid

conditions should have their blood concentration of theophylline monitored, and

doses of theophylline should be adjusted as necessary. The administration of

liothyronine increases the action of the blood thinning drug, warfarin

(Coumadin). Warfarin acts by reducing the concentration of factors in the body

that are necessary for blood to clot. The concentration of these clotting

factors in the body is determined by the body's rate of metabolism. In theory,

by increasing the body's metabolism (elimination) of these clotting factors,

thyroid hormones reduce the body's ability to clot and therefore enhance the

effects of warfarin. Since this can lead to excessive bleeding, the dose of

warfarin may need to be reduced. Digoxin (Lanoxin) is a drug

that is used to control heart rate. Individuals with hypothyroidism tend to be

more sensitive (respond more) to digoxin, and, conversely, individuals with

hyperthyroidism are less responsive to digoxin. Therefore, increasing the level

of thyroid hormone in the body may warrant an increase in the dose of digoxin.

The mechanism for this interaction is not clear, but it may involve changes in

the absorption of digoxin, digoxin metabolism, or the effects of thyroid hormone

on the heart. Cholestyramine (Questran) and colestipol (Colestid) reduce the

effects of liothyronine and possibly other thyroid hormones by attaching to the

hormones in the intestine and preventing their absorption from the intestine.

Therefore, cholestyramine and colestipol should be taken approximately six hours

before or after liothyronine or other thyroid hormones so as not to interfere

with their absorption.

PREGNANCY: Thyroid hormones do not easily cross the placenta and, therefore,

are safe for pregnant women to take.

NURSING MOTHERS:Very small amounts of thyroid hormone may be excreted in

breast milk. This is not a serious problem for breast fed infants.

SIDE EFFECTS: Liothyronine therapy generally is well-tolerated. If symptoms

occur, they usually occur because there are toxic (too high) levels of thyroid

hormone (hyperthyroidism). Symptoms of hyperthyroidism include: chest pain,

increased heart rate, cardiac arrest, excessive sweating, heat intolerance,

nervousness, headache, tremor, insomnia, diarrhea, vomiting, weight loss, or

fever. Women also may experience irregular menstrual cycles. Since thyroid

hormone affects heart rate and metabolism, the impact of treatment of thyroid

hormone on the control of diseases such as atrial fibrillation, diabetes and

high cholesterol levels always should be considered.

love, in justice, in liberty, and in equality.” -Hugo Chavez Frias

I take T3 with Armour. It is usually not necessary unless you have

thyroid resistance at a cellular level. Why does your doctor think this

is better for you? There are other thyroid hormones in Armour that are

very beneficial in treating thyroid disease like T1, T2 and T3 and T4 as

well as Calcitonin.
