Generic name: Natural thyroid hormones TC and TDBrand names: Armour Thyroid
Armour Thyroid is prescribed when your thyroid gland is unable to produce enough hormone. It is also used to treat or prevent goiter (enlargement of the thyroid gland), and is given in a "suppression test" to diagnose an overactive thyroid.
Although Armour Thyroid will speed up your metabolism, it is not effective as a weight-loss drug and should not be used for that purpose. Too much Armour Thyroid may cause severe side effects, especially if you are also taking appetite suppressants.
Take Armour Thyroid exactly as prescribed by your doctor. There is no "typical" dosage; the amount you need to take will depend on how much thyroid hormone your body is able to produce. Take no more or less than the amount your doctor prescribes. Take your dose at the same time every day for consistent effect.
Do not change brands of medication without consulting your doctor.
If you are taking Armour Thyroid to compensate for an underactive thyroid gland, you will probably need to take the medication indefinitely.
Side effects are rare when Armour Thyroid is taken at the correct dosage. However, taking too much medication or increasing the dosage too quickly may lead to overstimulation of the thyroid gland.
Although children treated with Armour Thyroid may initially lose some hair, the hair loss is temporary.
You should not take Armour Thyroid if you have ever had an allergic reaction to Armour Thyroid; your thyroid gland is overactive; or your adrenal glands are not making enough corticosteroid hormone.
If you are elderly, particularly if you suffer from angina (chest pain due to a heart condition), you should take Armour Thyroid at a lower dosage, and your doctor should schedule frequent checkups.
Armour Thyroid tends to aggravate symptoms of diabetes and underactive adrenal glands. If you take medication to treat one of these disorders, your dosage of that medication will probably need to be adjusted once you start taking Armour Thyroid.
If you take Armour Thyroid with certain other drugs, the effect of either drug could be increased, decreased, or altered. It is especially important to check with your doctor before combining Armour Thyroid with the following:Asthma medications such as theophyllineBlood thinners such as warfarin sodiumCholestyramineColestipolEstrogen preparations (including some birth control pills such as conjugated estrogens)InsulinOral diabetes drugs such as chlorpropamide and glipizide
If you need to take Armour Thyroid because of a thyroid hormone deficiency, you may continue using the medication during pregnancy, but your doctor will test you regularly and may change your dosage. Once your baby is born, you may breastfeed while continuing treatment with Armour Thyroid.
Your doctor will tailor the dosage of Armour Thyroid to meet your individual requirements, taking into consideration the status of your thyroid gland and any other medical conditions you may have.
An overdose of Armour Thyroid will speed up all of the body's vital processes, causing physical and mental hyperactivity, increased appetite, excessive sweating, chest pain, increased pulse rate, palpitations, nervousness, intolerance to heat, and possibly tremors or a rapid heartbeat.
