Comparison between most popular thyroid medicines: Levothroid vs Synthroid

07 Sep

Hyperthyroidism and hypothyroidism are the common disorders related to the thyroid gland. These diseases occur due to the loss of balance of the thyroid hormones in the blood. The main function of the thyroid gland is the production of hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones are required for the normal processes in the body. An increase in the synthesis of T3 and T4 leads to a disease known as hyperthyroidism and a decrease in the synthesis of these hormones leads to a disease known as hypothyroidism. Synthroid and Levothroid are the most commonly prescribed drugs for the management of hypothyroidism.

What is Levothroid?

It is considered one of the best drugs for the management of hypothyroidism. The active component of this drug is Levothyroxine sodium. Levothroid helps in the management of this disease by causing an increase in the level of thyroxine and triiodothyronine in the blood. Patients, who are suffering from goiter due to cancer of the thyroid gland, imbalance of hormones, radiation treatment and operative procedures, can use this drug for managing it effectively. The symptoms of goiter, such as unusual weakness, speech impediments and increased sensitivity to cold, can be managed well by using this medicine.

What is Synthroid?

It is also an effective drug for the management of hypothyroidism. The active component of this drug is Levothyroxine sodium, which helps in the management of hypothyroidism by increasing the levels of thyroxine and triiodothyronine in the body. Use of this medicine is highly beneficial for treating congenital or acquired hypothyroidism. However, this medicine should not be used for treating hypothyroidism occurring during the recovery phase of subacute thyroiditis. Primary hypothyroidism that occurs as a result of abnormalities of the thyroid gland and secondary hypothyroidism that occurs as a result of abnormalities of the pituitary gland can be managed well with the help of Synthroid. Patients can also use Synthroid for the treatment of tertiary hypothyroidism that is hypothalamic in origin. Subacute or chronic lymphocytic thyroiditis can also be managed well by using this medicine.

What is the recommended dose of Synthroid and Levothroid?

Patients can use Generic Levothroid in a dose of 1 tablet everyday. The exact dosage of this drug depends on the levels of thyroxine and triiodothyronine in the body. The recommended dosage of Synthroid is the same as that of Levothroid. Some other factors that should be considered while determining the dosage of Levothroid and Synthroid are; the age of the patient, cardiovascular status of the patient, use of other drugs and the patient’s body weight. Patients should leave a gap of atleast 4 hours between the consumption of Levothroid or Synthroid and any other drugs that can interfere with the absorption of these medicines.

Levothroid vs Synthroid:

Both, Levothroid and Synthroid, are very efficient for the management of hypothyroidism and other diseases related to the thyroid. Since the main ingredient of these drugs is the same, patients can use either one of them, based on their availability and price. Usage of Synthroid or Levothroid as recommended can help patients in the effective management of hypothyroidism.
