About Levothyroxine

Levothyroxine is a synthetic thyroid hormone that is used to treat hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormone. It works by replacing the thyroid hormone that your body is missing, helping to regulate your metabolism and energy levels.

Levothyroxine is a medication that is typically taken orally once a day, preferably in the morning on an empty stomach. It is important to take it consistently and at the same time each day to ensure that your thyroid levels remain stable.

It is important to follow your doctor’s instructions when taking Levothyroxine, as the dosage may need to be adjusted based on your thyroid levels and response to the medication. Do not stop taking Levothyroxine without consulting your doctor, as it is important to maintain your thyroid levels for proper functioning of your body.
