Levothyroxine IV Uses

Levothyroxine is used to treat an underactive thyroid (hypothyroidism). It is a man-made substance that replaces the natural substance (thyroid hormone) that is normally produced by the thyroid gland. Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery. Having enough thyroid hormone in your bloodstream is important for maintaining normal mental and physical activity. In children, having enough thyroid hormone is important for normal mental and physical development.

This medication is also used to treat other types of thyroid disorders (e.g., certain types of goiters, thyroid cancer). It is also used to test thyroid activity.

How To Use Levothyroxine IV

This medication is given by injection into a vein by a health care professional. Some brands may also be given by injection into a muscle by a health care professional. It is usually given once a day or as directed by your doctor. Dosage is based on your medical condition, thyroid hormone levels, and response to treatment.

Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time each day. Do not stop using this medication without consulting with your doctor. Thyroid replacement treatment is usually taken for life.

Symptoms of low thyroid levels include tiredness, muscle aches, constipation, dry skin, weight gain, slow heartbeat, or sensitivity to cold. These symptoms should improve in a few days as your body adjusts to this medication. Tell your doctor if your symptoms persist or worsen.
