Levothroid is the brand name of the generic medication levothyroxine. It is used to treat hormone imbalances in the thyroid gland. It is as a hormone replacement therapy.
How it works
Thyroxin and tri-iodothyronine which are hormones produced by the thyroid gland are important for the maintenance of energy and metabolism in your body. The condition in which these hormones are not produced enough in your body is known as Hypothyroidism. Subsequently, it reduces metabolism and leads to problems like weight gain and weakness of the immune system. Levothroid is a synthetic hormone that matches Thyroxin and tri-iodothyronine and it works by performing the same functions as these hormones in your body.
When a person is diagnosed with hypothyroidism, this medication is usually prescribed to be taken for the rest of that person’s life since the thyroid gland is unable to produce hormones.
Levothroid treats underactive thyroid glands (hypothyroidism). It is also prescribed to treat and prevent goiter (enlargement of the thyroid gland).
The dosage of Levothroid depends on the patient’s age, body weight, capacity of drug tolerance, health problems and cardiovascular status.
Levothroid works best when it is taken on an empty stomach. It is usually taken once a day 30 minutes to an hour before breakfast. Results of this drug will start to manifest after 4 to 6 weeks of continuous intake.
The dose recommended for adults who have been diagnosed with hypothyroidism only recently is 1.7 mcg/kg per day. Patients above 50 with hypothyroidism who also have underlying cardiac problems are recommended a dose of 25-50 mcg per day.
Persons with severe hypothyroidism should take a dose of 12.5-25 mcg per day and introduce increments of 25 mcg to the dose every 2 to 4 weeks.
The pediatric dose for infants is 10-15 mcg per day. The dose can be increased in a month as advised by your doctor. For children, the dose is usually adjusted according to body weight and age. The older they get, the smaller the dose is.
Many who take Levothroid do not experience side effects. However, a small percentage of patients experience side effects such as:
Rapid heart beats
Shortness of breath
Swelling of ankles
These side effects are not to be overlooked. If you experience any of them after taking Levothroid, seek medical care immediately.
