Eltroxin is an orall medication indicated to treat an underactive thyroid (hypothyroidism). It is a synthetic version of the hormone thyroxine, which is normally produced by the thyroid gland. It contains an active ingredient called Levothyroxine. Levothyroxine works by replacing the missing thyroid hormone in the body.
Levothyroxine replaces or provides more thyroid hormone to the body when the thyroid gland is unable to produce enough thyroxine. Thyroxine is responsible for regulating metabolism and other bodily functions. By increasing the levels of thyroid hormone in the body, Eltroxin helps to reduce the symptoms of an underactive thyroid gland (hypothyroidism), which commonly include fatigue, weight gain, and depression.
Uses and Dosage
Levothyroxine is typically taken in the form of tablets, which should be taken by mouth as instructed by your doctor. The recommended dosage is usually once daily on an empty stomach, 30 minutes to 1 hour before breakfast. Take the tablet with a full glass of water unless your doctor gives you other instructions.
Be sure to swallow it whole without crushing, splitting, or chewing tablet. However, if you are giving the tablet to an infant or child who cannot swallow whole tablets, you can crush the tablet and mix it with 1 to 2 teaspoons of water. Then, give the mixture to the child immediately using a spoon or dropper. Do not prepare the mixture in advance or mix the tablet in soy infant formula. Always follow your doctor's instructions carefully and talk to your pharmacist if you have any questions about taking levothyroxine.
