Levothyroxine Drug Description
Hypothyroidism is a common medical condition in which the thyroid gland does not produce enough levothyroxine, which causes the following symptoms:
- Weakness and tiredness
- Dry hair and skin
- Hair loss
- Depression and irritability
Hypothyroidism can be effectively treated with Levothyroxine, which is a replacement for the naturally occurring thyroid hormone. Levothyroxine is also prescribed for treating a variety of thyroid problems, among which are goiter and certain types of thyroid cancer.
Levothyroxine is also used along with antidepressants for the treatment of depression, although it has not been approved for this use.
Mechanism of Action
Active component levothyroxine, which is a manufactured version of the thyroid hormone levothyroxine (also called T4). Although Levothyroxine is a synthetic hormone, it is identical to the naturally occurring thyroid hormone.
Levothyroxine works by increasing the level of thyroid hormone in the body, thereby improving the symptoms of hypothyroidism.
It usually takes several weeks to notice Levothyroxine benefits.
For most patients, Levothyroxine is taken once a day, usually in the morning. It is recommended that you take Levothyroxine on an empty stomach 30-60 minutes prior to breakfast. Levothyroxine tablets can be crushed and mixed with water if needed.
The dosage of Levothyroxine will vary from patient to patient because there are different degrees of hypothyroidism. Your dose will be based on the result of blood tests and some other factors, among which are your age and other conditions you have.
It may take as long as several months to determine the right dose, and you doctor may need to adjust your dose from time to time.
Most patients are usually started on lower dosages of Levothyroxine, which is gradually increased to the average of 100-125 mcd a day (1.7 mcg per kg per day). The maximum daily dosage of Levothyroxine is 200 mcg.
You should understand that larger doses of Levothyroxine may be harmful to your health. If you take too much of levothyroxine, you may develop the symptoms of hyperthyroidism. That’s why your doctor will measure the amount of T4 in your blood regularly to ensure you are taking the right dosage of Levothyroxine.
Do not stop taking Levothyroxine suddenly. Your doctor may recommend that you gradually reduce your dosage before stopping completely. Always follow your doctor’s orders or the directions in the Patient Information Leaflet when taking Levothyroxine.
Levothyroxine tablets come in a number of strengths, including Levothyroxine 25 mg, Levothyroxine 50 mg, Levothyroxine 75 mg, Levothyroxine 100 mg, Levothyroxine 125 mg, and Levothyroxine 200 mg.
If your dosage is 100 mg per day, you can use Levothyroxine 100 mg. But if your doctor will decrease your dose to 50 mg per day, you can split the tablet in half.
