Levothyroxine Sodium

Levothyroxine Sodium

Where is Levothyroxine Sodium used?

Levothyroxine Sodium is a hormone medication used to treat hypothyroidism or underactive thyroid. Low levels of thyroid hormone can happen naturally or might be injured by radiation or medications. This medication provides more thyroid hormone. Consuming sufficient thyroid hormone is important for maintaining normal mental and physical activity. Having sufficient thyroid hormone in children is important for physical and normal mental development. 

How does Levothyroxine Sodium work?

Levothyroxine Sodium is similar to the natural hormone thyroxine which is normally produced by the thyroid gland. The thyroid gland usually creates and releases two thyroid hormones which are thyroxine (T4) and tri-iodothyronine (T3). T3 is the more active thyroid hormone and T4 is converted into T3 in several parts of the body. These hormones are accountable for preserving a regular rate of metabolism in the body. If the thyroid gland is incapable to create normal quantities of thyroxine, the levels of both thyroid hormones in the blood drop. This is known as hypothyroidism. It results in a reduced rate of metabolism which leads to symptoms such as tiredness, weight gain, and intolerance to cold.

This medicine works by replacing the thyroxine that would normally be produced naturally by your thyroid gland. This returns levels of T3 and T4 to normal. 

How is Levothyroxine Sodium taken?

Levothyroxine Sodium is usually taken once a day by mouth as directed by your doctor. Each dose is taken on an empty stomach 30 minutes to an hour before breakfast. Take the tablet with a full glass of water if your doctor directs you otherwise.

For children that cannot swallow the whole tablet, you can crush the tablet and mix it in 1 to 2 teaspoons of water. Give right away the medicine using a dropper or spoon.

Take it at the same time each day to help you remember. Use this medication regularly to get the most benefit from it. Do not stop taking this prescription without consulting first your doctor. this type of treatment is usually taken for life. 

What are the precautions in taking Levothyroxine Sodium?

  • While taking this medication, you will need to have regular blood tests to monitor your thyroid hormone levels. This helps your doctor to prescribe the correct dose to get your thyroid hormones into the normal range. It may take a few weeks to establish the dose that works for you. 
  • Levothyroxine Sodium can interact with other medications, vitamins, or herbs you may be taking. An interaction is when a substance changes the way a drug works.
