For which conditions or diseases is Thyroid pills prescribed?


When taken properly, thyroid hormones are used to treat the symptoms of hypothyroidism (a disorder in which the thyroid gland does not produce enough thyroid hormone). Symptoms of hypothyroidism include lack of energy, depression, constipation, weight gain, hair loss, dry skin, thick and dry hair and muscle cramps.

One may also experience decreased concentration, irritation, and pain, inflammation (swelling) of the legs and increase of sensitivity to cold. The thyroid is also used to treat goiter (enlarged thyroid gland). It belongs to a class of medications called thyroid agents and works by providing the thyroid hormone that is normally produced by the body.

The dosage form available for the thyroid is capsule shaped. All of Absolute Pharmacy’s capsules are made according to the standards of USP 795. The quality of our product is assured.

Mechanism of action:

The dried thyroid contains Liothyronine and Levothyroxine; Liothyronine (T3) is the main hormone, while levothyroxine (T4) is the hormone secreted by the thyroid gland, which metabolizes T3 into peripheral tissues. T4 and TSH concentrations are commonly used to monitor thyroid function.


The thyroid hormones come packaged as capsules to take by mouth. It is usually taken once a day before breakfast. It should be taken around the same time every day. Follow the instructions on the prescription label carefully and ask your doctor or pharmacist for anything you do not understand. Use the medication exactly as directed. Do not use more or less than the indicated dose or more often than prescribed by your doctor. Your doctor may start with a low dose of the medication and increase it gradually.

Thyroid hormones help control the symptoms of hypothyroidism, but it does not cure the disorder. It may take several weeks before you notice a change in your symptoms. To control the symptoms of hypothyroidism, you will probably need to take thyroid hormones for the rest of your life.
